In the transition layer, there is no free movement of electrons and holes, and in the ideal state, it almost has insulating properties, and it is difficult for current to flow. However, the electric field between the drain and the source is actually the contact between the two transition layers and the drain and the lower part of the gate, and the high-speed electrons pulled by the drift field pass through the transition layer.

[0003] In the prior art, during the production and manufacturing of the field effect transistor, the chip and the pin generally need to be packaged. When the field effect transistor is packaged, the chip is usually placed in the inside of the shell, and the pin is placed at the corresponding position of the chip. The shell is heated and packaged by hot melting, but in this process, after the chip and the pin are placed and packaged, the yield is tested. At this time, the packaged chip and pin are fixed in position, so that the electrical connection between the chip and the pin cannot be measured, and then the poor field effect transistor cannot be adjusted again after packaging. The electrical position between the chip and the pin, thereby affecting the packaging production effect. SUMMARY
