Concept of IC electronic components industry

 

Passive components

 

Is the indispensable basic components in electronic products. Electronic circuit has active and passive two types of devices, passive components can be action, is don't have to jump and adjust the voltage, current storage electrostatic, prevention and control of electromagnetic interference, the function of filtering impurities such as current. Relative to the active components, passive components are at the time of voltage change,

 

Resistance and impedance will not change. Passive components can cover the three categories of products: resistor, inductor and capacitor.

Semiconductor discrete devices

 

Mainly including semiconductor diode, transistor, transistor, MOs field effect tube array, junction field effect tubes, photoelectric coupler, SCR and other ends and three terminal device.

Passive and active components

 

Simply speak is need to can (electric) source device is called active device, can need not (electric) source device is passive components. Active devices are commonly used to signal amplification, transformation, passive components used for signal transmission, or through the directional signal amplification ". Capacitor, resistor and inductor are passive components, Ic, modules, etc are all active device.

 

Moore's law

 

INTEL co-founder Gordon Moore, the rule of thumb, he once described: "with the increase the complexity of the chip circuit, element number will increase, but the cost of each component is falling by half a year." Moore's law seems very simple, but for the guidance of the semiconductor industry development is of far-reaching significance. Some analysts predict that Moore's law will failure... The complexity of the circuit will eventually reach the limit, Moore's law is not actually a laws of physics, but a prophecy, is a kind of self motivation mechanism, as long as the semiconductor technology and the development of economy also can meet the needs of the market, Moore's law will continue to survive, just a slow speed.

The wafer

 

More refers to the single crystal silicon wafer by ordinary silicon salad is made refined but become, is the most commonly used semiconductor materials, according to its diameter is divided into 4 inches, 5 inches and 6 inches, 8 inches specifications, such as the recent developed 12 inches or more large size, the greater the wafer, can be on the same wafer production of Ic is much, can reduce cost, but higher material technology and production technology.
