Describe briefly the construction of p-channel FET. |
|
Answer» For fabricating p-channel FET, first a narrow bar of p type semiconductor material is taken and then two pn junctions are diffused on opposite sides of its middle part. These junctions form two pn junctions and area between these gates is called the channel. The two p regions are internally connected and a single lead is brought out which is called gate terminal. Ohmic contacts are made at the two ends of the bar called source terminals and the other drain terminal D. |
