1. Integrated circuit. It is one of the most active fields in the development of semiconductor technology and has developed to the stage of large-scale integration. Tens of thousands of transistors can be made on a silicon chip of several square millimeters, and a microprocessor can be made on a silicon chip, or other more complex circuit functions can be completed. The development direction of integrated circuits is to achieve higher integration and micro power consumption, and to make the information processing speed reach picosecond level.
2. Microwave devices. Semiconductor microwave devices include receiving, controlling and transmitting devices. Receiving devices below the millimeter wave band are widely used. In the centimeter band, the power of the transmitting device has reached several watts, and people are developing new devices and technologies to obtain greater output power.
3. Optoelectronic devices. The development of semiconductor light-emitting, imaging devices and laser devices has made optoelectronic devices an important field. Their scope of application is mainly: optical communication, digital display, image reception, optical integration, etc. | semiconductor chip
