Abstract
PURPOSE: To make possible a treatment in usual manner to prevent disconnection due to the level difference by forming protective film using hard glass with a high melting poing and a high resistance to humidity, and making the surface glassy by of laser beam irradiation.
CONSTITUTION: A protective film of hard glass with a high resistivity to humidity is formed on a semiconductor device. An electrode contact window is made by patterning on the glass protective film by the ordinary photo lithography technique. Then surface is made glassy by reflow of laser beam radiation.
