Abstract

PURPOSE:To give a heat-resistance lift-off mask and to make possible a high- temperature deposition and a high-temperature heat treatment by a method wherein an SiO2 film and an SiNx film containing a small quantity of hydrogen are laminated on a substrate to form a fine pattern with a prescribed etching liquid. CONSTITUTION:An SiO2 film 12 and an SiNx film 13 containing a small quantity of hydrogen are deposited in order on a substrate 11 consisting of InP and so on. A fine pattern is formed on the films 12 and 13 using a mixed etching liquid of an HF etching liquid, an NH4F etching liquid and an H2O etching liquid. Then, after being deposited, AuZn is heat-treated (450 deg.C) and is dipped in a mixed etching liquid of an HF etching liquid, an NH4F etching liquid and an H2O etching liquid to lift off an AuZn film 14.
