Semiconductors: Specialized Devices

Although every semiconductor device is made up of P-Type and N-Type semiconductor materials (plus assorted connections to them), there is still room for many different variations. We've already looked at adding more junctions to devices. Now, what if we change other factors? We can make each region thicker or thinner, we can make it wide or narrow, long or short. We can add the impurities to a greater or lesser extent, and we can use different combinations of impurities.

Any of these variations will change the properties of the individual semiconductor region, and will affect the behavior of the overall semiconductor device. These pages show how that works.
