Special Transistors: Components and Functions

In the field of electronics, transistors are important components, and their structure and operating principles play a crucial role in the flipping of modern electronic devices. Among them, special transistors are transistors with similar properties and functions, which require specific materials and skills for planning and manufacturing. This article will deepen the discussion on which crystal components are included in special transistors, and explain their functions and applications together.

    Our country requires students to understand what special transistors are. A special transistor does not refer to a transistor composed of a specific crystal, but to a transistor with special functions in China under a specific operating environment and conditions. The special functions of these enterprises may stem from the planning of transistor structures, the selection of materials, or the production process.

1、 Structural planning

The structural planning of special transistors directly affects their functionality. For example, a bipolar transistor (BJT) is a special type of transistor composed of two PN junctions that allow for amplification and switching. For example, in field-effect transistors (FETs), the distance between the gate and drain can be precisely controlled, allowing the current to be precisely controlled. Domestic eMMC

2、 Material selection

Different materials can endow transistors with different characteristics. For example, silicon is the most common semiconductor material used to manufacture general transistors. However, gallium phosphide (GaP) is often used to manufacture high-speed and high-temperature transistors due to its high electron mobility and thermal conductivity. In addition, new semiconductor materials such as gallium arsenide (GaAs) and gallium nitride (GaN) are also used to manufacture special transistors.

3、 Process progress

Special processes can also affect the functionality of transistors. For example, by changing the doping concentration or increasing impurities, the conductivity of the transistor can be modified; By changing the temperature or pressure, it can affect the stability and reliability of the transistor.

Special transistors are determined by structural planning, material selection, and process selection. Each special transistor has its own unique operating principle and application field, which brings us a lot of convenience in our daily life.
