In the art, the total gate charge stands for electric charges required for the gate when the MOSFET is in a fully conductive state. However, in almost all these existing gate processes to produce the MOSFET, shortcomings of a high total gate charge (Qg) and a high practical figure of merit (FOM) are usually seen. Generally speaking, the production of the MOSFET is firstly to form an epitaxial layer on a semiconductor substrate, then to form trenches on the epitaxial layer, and finally to form a gate of the transistor by various steps in the corresponding trenches. With blooming growths in modern technology, one of the progresses in the semiconductor manufacturing technique is the development of the metal-oxide-semiconductor field effect transistor (MOSFET).Ĭurrently, various manufacturing processes have been developed to produce the MOSFET. The invention relates to a field effect transistor and a method for manufacturing this field effect transistor, and more particularly to the field effect transistor and the method for manufacturing the field effect transistor that include at least one electrode portion having a multi-width structure.

These are the components that make a transistor also called a three terminal device because there are 3 electrodes.įollowing injection of charges into the organic semi-conductor, those charges will travel and be collected at the other electrodes.This application claims the benefit of Taiwan Patent Application Serial No. For a given voltage between the source and drain, the voltage of the gate can either be decreased such that there is a small injection or current or it can be increased to have a very large injection of charges into the semi-conductor and a large current. The gate will modulate the injection and produce a switching effect. When there is a voltage difference between the source and drain, the amount of charges that will be injected into the semi-conductor will be modulated by the voltage at the gate. This is one of the configurations possible. The organic semi-conductor sits between these. You have two other electrodes referred to as the source and the drain. Next there is a thin insulator called a dielectric. The first electrode will be referred to as a gate. Those electrons must migrate and be collected. Now all is needed are the electrons and the holes. However, in a field-effect transistor, the charge injection is modulated through a third electrode called a gate. In the case of light-emitting diode and photovoltaic cell there are only two electrodes. The first one is the injection of charges into the semi-conductor. There are three major processes involved with organic field-effect transistors charge injection, charge transport, and charge collection. An organic field effect transistor (OFET) uses an electrically active organic compound as the switching component. A field effect transistor (FET) uses an electric field to change the conductivity of an semiconductor material.
