S4800型SEM操作指南S-4800具体操作过程1.日常开机按下DISPLAY开关至“━”,PC自动开机进入用户界面并自动运行PC_SEM程序,以空口令登入。
2.轰击(flashing)FE-SEM在作样之前,必须要进行轰击(作为电子源的FE尖端的清洁)。
在开始使用时,轰击频率为一次。
但是,电压外加时间累计超过8小时,发射电流开始不稳定,需要再次轰击。
轰击后可以立即观察图象。
但是在最初的1小时左右,有时会有图象干扰(图象中出现明暗的横线)。
进行高分辨率的观察时,最好在轰击完1小时以上之后进行观察。
执行过程:(1)点击控制面板上的加速电压显示区域,出现加速电压HV设定画面。
(2)点击“Flashing”键后,出现轰击执行窗口。
(3)确认轰击强度是否确实是“2”后,点击“执行”键。
HV的Ie(发射电流)显示器显示2秒钟轰击产生的发射电流,电流值大约为20uA-30uA,有时仅轰击一次,达不到所要求的值,这时需要连续轰击2-3次。
(为了保护FE灯丝,中间间隔30秒钟后,才可以进行下一次轰击。
)3.样品制备及装入3.1 样品制备相对简单,原则上只要能放入样品室的样品,都可进行观察。
高度保持在2cm以内,直径在4cm以内。
但是,样品在化学上和物理上必须要保持稳定,在真空中和电子束轰击下不挥发或变形,没有腐蚀性和放射性。
由于光源是电子,样品必须导电,非导电样品可喷镀金膜。
金膜在一定程度上会影响样品原有形貌。
带有磁性的样品,由于物镜有强磁性,制样必须非常小心,防止在强磁场中样品被吸入物镜或分散在样品室中。
操作过程:(1) 剪一小段导电胶,粘到样品台上。
(非导电样品可以用双面胶。
)(2) 把粉末撒到导电胶上,用吸耳球或高压氮气吹扫掉导电胶上未粘紧的粉末;若是块状样品,则把样品牢牢粘到导电胶上,用手轻轻推,样品不会左右晃动。
(3)样品若不导电,需要喷镀金膜。
3.2 样品装入:(1)把样品台装入样品座并调节样品表面与标尺在同一高度,旋紧。
Operating Procedure for Hitachi S-4800 Scanning Electron MicroscopeCFN Laboratory1L-32C.Black/G.WrightOperation of the Hitachi S-4800 Scanning Electron Microscope (SEM) requires specific user training and authorization. This operating procedure is meant as a general overview of tool operation and is NOT A SUBSTITUTE for obtaining proper training and authorization.Users should have reserved tool access via the FOM calendar.NIRTRILE GLOVES ARE TO BE WORN AT ALL TIMES when handling sample specimens, sample stages, and any parts to be introduced into the tool vacuum chamber. Suitable gloves are located on the workbench to the left of the Hitachi SEM.Sample PreparationSuitable samples for imaging will be mounted on solid flat substrates such as silicon or glass.Sample specimens must be mounted on a sample holder for insertion into the tool. Several different sample holder sizes are available. Sample holders are located on the workbench.Mount sample on sample holder. Specimens should be mounted using either double-sided sticky tape or clips. Silver paint is to be used only if absolutely necessary.Samples may be blown free of dust and debris using the can of compressed air located onthe laboratory workbench.Clean and organize sample preparation area when finished.Microscope PreparationObserve that microscope is energized and ready for operation. If any warning lights indicate a problem then STOP and contact a staff member.Log into the FOM and activate your reserved session to turn on the Hitachi computer.Loading a sampleAfter mounting sample on a sample holder, adjust the specimen height using the specimen height gauge located on the workbench. To adjust the height, loosen the lock screw and adjust the specimen height so that the height of the highest point of the specimen is the same as the bottom of the height gauge. Then tighten the lock screw by holding the fixed upper part of the holder..Move to the SEM console. Verify that there is no sample stage already loaded in the chamber by looking at the small camera monitor showing a view inside the chamber.Click the EXC button on the control panel. The stage inside the SEM will move to the specimen exchange position. Once this occurs the indicator beside the button will turn green. (Normally the stage will be left in the exchange position.)Press the AIR button on the specimen exchange chamber. After 15 sec. a buzzer will sound indicating that the chamber has been vented.Open the exchange chamber door. Be SURE to use the handle to open the chamber door and DO NOT USE THE SAMPLE LOAD ARM. Pulling on the arm in this way can damage the sample lock vacuum. The exchange chamber door is interlocked and will not open unless all vacuum conditions are satisfied.Confirm that the specimen exchange rod is in the UNLOCKED position by turning clockwise until the UNLOCK mark faces upwardsInsert the two spring pins at the end of the rod into holes of the specimen holder.While holding the specimen holder, turn the knob of the specimen exchange rod counterclockwise until the LOCK mark comes upwards. The sample holder is now lockedonto the load arm.Pull out the sample exchange rod completely and close the exchange chamber door.Press the EVAC button on the specimen exchange chamber. This will pump out the loadlock. Press the OPEN button to open the gate valve to the chamber, which will happen when a suitable low pressure has been achieved.After the gate valve opens, slide the specimen exchange rod all the way into the chamber WHILE LOOKING INTO THE CHAMBER on the small microscope screen toensure that the specimen holder inserts into the guide rails.Turn the specimen rod knob to the UNLOCKED position.Pull out the specimen exchange rod completely while VISUALLY WATCHING that the rod disengages from the sample holder.Press the CLOSE button on the specimen exchange chamber to close the gate valve. The sample is now loaded into the chamber.Applying the SEM high voltageClick the ON button on the control panel at the left of the HV DISPLAY area. You will be asked to verify the size (diameter and height) of the sample holder you are using. If the one displayed is in fact the one you are using, click OK. If not, clickCANCEL. Set the size of the sample holder you are using in the STAGE menu. If you are using the cross- section stage then you should select a stage size of 4 inches.High voltage can be applied only if the HV DISPLAY area on the control panel is blinking in yellow and blue. If the indicator is solid blue then the SEM conditions are not appropriate for high voltage application. Once the high voltage has been applied the indicator will display (nonblinking) yellow.Use the HV CONTROL dialog window to set SEM accelerating voltage and emission current.To set the accelerating voltage, select a voltage from the Vacc list box.To set an emission current, set a current in the SET Ie to list box. Hitachi recommends 10uA emission current for normal SEM operation.Click the ON button on the control panel at the left of the HV DISPLAY area. The SEM will automatically turn on the accelerating voltage, the extracting voltage, and the emission current. These values are displayed in the HV DISPLAY area. The electron gun airlock valve will automatically open upon completion of gun turn-on.Once the high voltage is applied the ON button will change to SET, allowing the user to set the emission current during high voltage operation. The OFF button turns off the high voltage. Note that during SEM operation the current will drop gradually over time. You can reset to the specified emission current (typically 10uA) by pressing SET.After high voltage turn-on a message will appear saying: “Stage is at specimen exchange position. Move to Home position?” Selecting YES will move the stage to the Home position such that the center of the sample holder will be directly underneath the electron beam.Obtaining a sample imageThere are many possible imaging variations for using the Hitachi S-4800 tool and these depend on the type of sample being imaged. We include here a summarized list of many commonly- used possibilities but do not provide detailed descriptions or an exhaustive list. The user is directed to the tool operating manual (located on the workbench to the left of the Hitachi SEM) for a complete discussion.Imaging mode:Selecting a Magnification Mode: The SEM has two magnification modes, HIGH MAG and LOW MAG. Most common applications will utilize the HIGH MAG mode.Within HIGH MAG magnification mode, user specifies:Probe current mode: NORMAL of HIGH. Most applications will utilizeNORMALFocus mode: UHR or HR. UHR mode allows full range of working distances.Working distance (WD). Shorter WD means higher resolution. Longer WDallows greater depth of focus and more sample tilting.Focus depth: Best resolution attainable with this value set to 1.0Specimen bias voltage: Specimen can be voltage-biased during imaging tominimize sample charging effects.Magnetic sample: Use this mode for observation of ferromagnetic samplesDegauss operation:Setting ABCC link: Automatically adjusts brightness and contrast during sample imaging.Column Alignment Operation: Obtaining the highest resolution image will involve aligning the electron optical column. This operation is done entirely through an electromagnetic alignment (i.e., using the computer interface) without need for touching any knobs on the SEM column. Alignment conditions are saved for each accelerating voltage and probe current setting such that only minimal alignment adjustment should be necessary.Press TV1 to obtain an image on the screen.Typically the beam can be tuned up using only an APERTURE ALIGNMENT. The procedure is as follows:Set the magnification to about 5,000 and position a point of interest in the center of the display.Focus the image and correct astigmatism.Click APERTURE ALIGN in the ALIGNMENT dialog box and make adjustments such that the wobbling motion of the image is minimized.Turn off the APERTURE ALIGN mode by clicking the OFF button.Sample imagingDetector selection: The SEM has two secondary electron detectors, the UPPER and the LOWER detectors. User can select either detector or alternatively image using a mixture of the two signals. Select a detector on the SIGNAL SELECT block of the OPERATION panel.Image Magnification: Select image magnification by dragging the mouse in the MAGNIFICATION INDICATION area on the CONTROL PANEL. The magnification can also be set by rotating the MAGNIFICATION knob on the control box.Focus and astigmatism correction: Iteratively adjust focus and astigmatism using the knobs on the SEM control box.Brightness and Contrast: Adjust brightness and contrast either manually by using BRIGHTNESS and CONTRAST knobs on SEM control panel or by pressing ABCC button for automatic control.The recorded images are stored in a memory buffer and displayed across the screen bottom. At the end of the session you will need to save them in the appropriate folder.Unloading sampleRemember to wear gloves when unloading samples.When finished imaging, turn off the high voltage by clicking OFF on the HV DISPLAY area. Move the sample stage to the exchange position by clicking the EXC button on the control panel. Once this occurs the indicator beside the button will turn green.Press the OPEN button on the specimen exchange chamber to open the gate valveTurn the knob on the specimen exchange rod clockwise so that the UNLOCK mark is facing upwards.Insert the specimen exchange rod straight into the chamber and fit the two spring pins into the holes at the end of the specimen holderTurn the knob counterclockwise so the LOCK mark comes upwards to hook on the sample holder.VISUALLY INSPECT that the sample holder comes out with the rod as you pull the rod all the way out of the chamber.Press the CLOSE button on the specimen exchange chamber to close the gate valve. Press AIR to vent the loadlock.Open the exchange door (by its handle) and turn knob clockwise to UNLOCK position. The sample holder can now be disengaged from the sample rod.Close specimen exchange chamber door and press EVAC to pump the loadlock back down.CleanupLog into the FOM computer and end your session. This will turn off the Hitachi computer.Unmount your samples from the sample holder.Return sample stage to appropriate stage storage box located near the workbench at the rear of the laboratory.Clean workbench area and properly dispose of any materials used during sample preparation.TURN OFF laboratory lights when leaving the room。
