Title: Dry etching
Inventor: KADOMURA SHINGO
IPC: H01L21/302
Filed: 1991-12-13
Abstract: PURPOSE:To provide a method of etching a GaAs/AlGaAs laminate in a highly anisotropic, highly selective, less contaminating manner without using chlorofluorocarbon. CONSTITUTION:Gate recesses of a HEMT are formed by etching an n<+>-GaAs layer 5 on an n<+>-AlGaAs layer 4 using a mixture gas of S2F2, S2Cl2, and N2. Gallium and arsenide are removed as their fluoride and chloride, while vaporized sulfur reacts with nitrogen to form a side wall protective film 7 of sulfur nitride composed mainly of polythiazyl (SN)x. As a result, an anisotropic recess 5a is obtained. The etching stops where the underlying n<+>-AlGaAs layer 4 is exposed, because AlFx is formed by the contribution of F'' derived from S2F2. The sulfur nitride is sublimated and decomposed easily by heating the wafer.

IPC: G10L25/15
Filed: 1992-12-07
Abstract: PURPOSE:To improve the clarity by emphasizing a voice formant. CONSTITUTION:Input signals are inputted into a band dividing filter 10 and are divided into N piecer of frequency bands. Then, an average level is obtained for each frequency band by level detectors 11-1 to 11-N and is stored in a buffer memory 12.
