Title: Method of etching semiconductor crystal
Inventor: KIKUCHI RIE
IPC: H01S5/00
Filed: 1991-12-27
Abstract: PURPOSE:To it possible to perform an etching, which has a high selectivity with an AlGaInP clad layer and a GaInP etching stop layer in an AlGaInP semiconductor crystal and is easily controlled, on the semiconductor crystal with good reproducibility, in a short time and with high accuracy. CONSTITUTION:When an AlGaInP clad layer is etched, the temperature of a sulfuric acid etching liquid is set at 29 deg.C or higher, the temperature of the sulfuric acid etching liquid is made to drop to 28 deg.C or lower at a point of time when the etching of this layer ends and a lower GaInP etching stop layer is prevented from being etched. In the case where the temperature of the sulfuric acid etching liquid is 28 deg.C or lower, the ratio, that is, the selection ratio, of the AlGaInP clad layer to the GaInP etching stop layer becomes a value of infinity and although the AlGaInP clad layer is etched, the GaInP etching stop layer is not etched. Accordingly, the temperature of the fulfuric acid etching liquid is set at 28 deg.C or lower from the first and the etching of the AlGaInP clad layer may be performed.
