Abstract: A transistor device includes a gate region disposed adjacent to a semiconductor substrate such that a low impedance channel is formed between a source region and drain region of a transistor device when a voltage is applied to its gate. The drain region of the device can be disposed aside the gate region on a common surface of the semiconductor substrate. The source region of the device also can be disposed adjacent to the substrate but on a side of the semiconductor substrate opposing the drain and/or gate regions. Based on this topology, a transistor device can be fabricated with a buried source to enhance its operating characteristics such as switching speed.

Abstract: A uniform tailored electrical field in a multigate field effect D-mode transistor is automatically provided by a feedback circuit which couples drain bias voltages to the gates of a multigate transistor to bias the gates incrementally such that the highest voltage is applied to the gate nearest the drain while the lowest voltage is applied to the gate nearest the source. E-mode multigate FET's carry higher gate voltage on the gate close to the source compared to a gate voltage on a last gate, located close to the drain. The proper distribution of gate voltages improves the transconductance G.sub.m of the transistor and decreases gate capacitance C.sub.gs, which increases the speed of operation of a multigate FETs.
