BICMOS TECHNOLOGY

SEMINAR ON BICMOS TECHNOLOGY : The history of semiconductor devices began in 1930 when Lienfed and Heil first to propose the MOSFET. However, it took 30 years before this idea was used for the operation of devices for use in practical applications, and up In late 1980, this trend took a turn when MOS technology caught up and there was a In the intersection between bipolar and MOS share.CMOS was finding more widespread use due to its low power dissipation, high density and a simple design, these that in 1990 CMOS covered more than 90% of full scale MOS.
In 1983, two-way compatible with the process is based on CMOS BiCMOS developed and both MOS and bipolar device manufactured on the same chip has been developed and studied. The purpose of BiCMOS CMOS sensor combines a bi-directional, and can take advantages of both the field level and the system. Since 1985, the state of the art CMOS-bipolar structures have been converging. BiCMOS Day has become one of prevailing technologies used for high speed, low power VLSI functional especially circuits BiCMOS process has been improved and integrated CMOS process without additional measures. Because the process steps required for both CMOS and bipolar are similar, these steps will be shared cane both.
