Unit Nine Microelectronics
Most electronic circuits are composed of active devices, e.g. transistors and diodes, together with resistors (for bias, collector load, impedance transformation, etc.) and capacitors (e.g. for coupling ac signals while blocking dc supplies). Each of these elements can be produced in a form suitable for integrated circuit inclusion within limitations, e.g. capacitance values must not be too large. Some elements are difficult to produce in a suitable form, e.g. inductive elements, or large capacitors. Usually some alternative circuit form can be devised that dispenses with the requirement. Otherwise they must be included as an external lumped element.

Unit 4 Microelectronics
Integrated circuits are small, light, rugged, and reliable. They require less power and lower voltages than equivalent macroscopic circuits; consequently they operate at lower temperatures, and individual components may be close together without exceeding the operating temperature limit. Relatively little stray capacitance and short time delays are produced because of the short interconnections between the individual components in IC. Maintenance is simplified because if a component of the IC fails the complete IC is usually replaced. Mass production techniques of plane technology have reduced the cost of many IC so that they are almost as inexpensive as a single transistor. Eventually most conventional circuits will be replaced by IC.
［2］ The reduction in power dissipation is particularly important where a complex circuit is to be concentrated into a small space. The problem of extracting the heat generated in the circuit may then be a difficult one.

Ambrose Fleming, allowing the change of alternating current into a direct one-way signal.（二极管） ❖ 1906: First electronic triode vacuum tube is built by American electrical engineer Lee De Forest, allowing signals to be controlled and amplified. Technology of electronics is born. （三极管） ❖ Late 1940‘s: The Transistor.（晶体管） ❖ 1947: The point-contact bipolar transistor is invented by Bell Lab‘s Bardeen, Shockley, and Brattain.（点接触双极晶体管） ❖ 1951: Junction field-effect transistor (JFET) is invented.（结型 场效应管） ❖ 1952: Single-crystal silicon is fabricated.（单晶硅） ❖ 1954: Oxide masking process is developed.（氧化模处理）
❖ 微型化是指减少元件和电路的几何尺寸, 从而增加封装 密度、降低功耗、减少信号传播延迟。
❖ The integrated circuit is a group of transistors manufactured from a single piece of material and connected together internally, without extra wiring . Integrated circuits are also called ICs or chips.
