摘要: Static induction transistor (SIT) having a short-channel structure is characterized by small gate capacitance, high transconductance, and nonsaturation current-voltage characteristic. The major mechanism of current transport in SIT majority-carrier injection due to barrier height control at the intrinsic channel. When channel completely pinched off gate-to-channel built-in voltage junction-gate (JSIT), there appears normally-off SIT. In forward bias operation JSIT, which called bipolar mode (BSIT), switching speed far more improved from conventional JSIT. BSIT exhibits saturation BSIT, drain for onset lower than that density very high, leading characteristics low impedance, gain. Applications LSI are discussed especially concentrating on BSIT. logic circuit (SITL) containing short propagation delay time power dissipation promising future development VLSI.
