Abstract

PURPOSE:To remove the residual adhesive from the surface of a multiple elements semiconductor thin layer without affecting th substrate or the like by etching the surface of the thin layer with a mixture solution of acetic acid and hydrogen peroxide once. CONSTITUTION:Pb1-xSnxTe crystalline layer containing different composition is formed as a buffer layer 2, an active layer 3 and a top layer 4 on a PbTe substrate 1 by a liquid phase epitaxial method. Thereafter, an etching solution containing acetic acid (containing 99% of CH3COOH) and hydrogen peroxide (containing 35% of H2O2) at 1:1 of volumetric ratio as mixed and heated at 40 deg.C is used to etch the surface of the top layer 4 of the substrate 1 for approx. 5-10min, and the layer 4 is then rinsed with water.
