Abstract: PURPOSE:To reduce environmental contamination due to semiconductor processes by using CF4, NF3, or mixed gas SF6 and Cl2 when the area between source and drain electrodes on a GaAs cap layer is selectively etched to expose an active layer for forming a gate electrode. CONSTITUTION:GaAs cap layers 3 are formed on an active layer 2, and a source electrode 4 and a drain electrode 5 are formed and isolated. The area between the source and drain is selectively etched with CF4, NF3, or mixed gas SF6 and Cl2 to expose the active layer 2, and a gate electrode is formed. Since such a gas consisting of CF4, NF3 and SF6 mixed gas, instead of CCl2F2, is used in the selective etching, it is possible to reduce environmental contamination and effects on the ozone layer while improving the performance of a high- electron-mobility transistor.

IPC: H01L27/06
Filed: 1978-06-13
Abstract: PURPOSE: To prevent a switching transistor from malfunctioning by eliminating the need for the control of the absolute value of a leak current, by forming the switching transistor and leak compensating transistor on the same chip.  
     CONSTITUTION: On ordinary P-type semiconductor substrate 1, N-type layer 2 is crystal-grown and then separated by forming P-type layer 3 in layer 2. Lateral switching transistor Tr1 is formed by using P-type layer 4 on one layer 2 for its emitter, N-type layer 6 for its base and P-type layer 5 for its collector, and longitudinal leak-compensating Tr2 is formed by using N-type layer 7 on the other layer 2 for its emitter, P type-layer 4 for its base and N-type layer 7 in it for its collector. In this constitution, the base of Tr2 is made open and Tr2 connected between the base and emitter of Tr1 in series. As a result, the leak current of Tr2 is used as a bias current between the base and emitter of Tr1, so that when no signal arrives, the absolute value of the leak current between the collector and emitter of Tr1 can be decreased.
