Title: Dry etching method
Inventor: MUTO KATSUHIKO
IPC: H01L21/3065
Filed: 1989-04-10
Abstract: PURPOSE:To form a wall of side to be etched in a desired curved face with satisfactory controllability by etching while raising or lowering the temperature of a semiconductor by using an etching mask, having an inclined opening end face and different chemical reactivity with reactive particles from that of a semiconductor. CONSTITUTION:An opening end face is initially inclined on a semiconductor 19 of InP, and an etching mask 20 made of SiO2 is formed. It is etched while raising (lowering) the temperature of a substrate (semiconductor 19) by means of reactive ion etching technique, etc. In this case, the etching rate of the SiO2 is not substantially increased with the rise of the substrate temperature but the etching rate of the InP is increased. Accordingly, a vertical etching rate is increased (or decreased) upon progress of the etching. As a result, the wall of the side to be etched becomes recess (protruding), thereby forming the sidewall to be etched having a desired curved face with satisfactory controllability.
