What is a flat transistor?

Planar Transistor was invented by Jean Hoeni in 1959. The design of the planar transistor improved on earlier designs by making them cheaper to create, in bulk and better in amplifying the electric input. The planar transistor is built in layers and can have all its connections in the same plane. Many dirts are added to this base, allowing the wire to be better. The second layer of semiconductor with fewer dirt is then laid on the base. After the second layer is on the spot, it is centering up and leaves the thick edges of the second material on the sides and a thin layer above the square bowl -shaped base. The center of this layer is reacked again and creates a smaller bowl. The material similar to the first layer of the planar transisutor is then added. The second, third and fourth layers are carried out by flushing with the peak of the transistor.

positive and negative components of a flat semiconductorare accessible in the same plane of the device. Metal connectors can be connected to the transistor after the components are on site, allowing the device to receive and emit electricity. The transistor receives the input from the first layer and releases the fourth output. The third layer is used to start the charge into the transistor so that it can amplify the input.

Although the design of the device is slightly more complicated than previous transistors, many planar transistors can be done simultaneously. This reduces the amount of time and then the money needed to produce transistors and helped pave the way for more affordable electronics. These types of transistors can also increase input to higher levels than Earlier Models of transistors.

In previous transistors, an oxide layer was removed from the transistor, which is naturally formed on the semiconductor supersa to prevent contamination. This meant that the fine intersections between the positive and negative parts of the transistor had to be exposed. Construction of transistor in layers as pHe came to life, incorporated the oxide layer as a protective feature for intersections.
