Abstract

PURPOSE: To stabilize through the process consisting of esterizing, coating with alcoholic liquid, and heat-treating, the etched surface of protective glass film.
CONSTITUTION: Mesa-grooves 5aW5c and 6aW6c are formed in a semiconductor substrate 1, and protective glass films 7aW7c and 8aW8c in said mesa-grooves 5aW5c and 6aW6c. Next, the whole structures of the heat-oxidized films 9 and 10 formed in preceding process are removed by etching for forming an electrode. Next, said protective films 7aW7c and 8aW8c are esterized by immersing said substrate 1 in ethanol for example. Next, said protective films 7aW7c and 8aW8c are coated with alcoholic liquid such as organic silane and heat-treated for forming oxidized films 11aW11b and 12aW12b at the surface thereof. Thereby, the surface, unstabilized through etching process, of said protective films 7aW7c and 8aW8c can be stabilized. Thus, said surface can be stabilized in characteristic since undesired matters do not attach again thereto after system assembly.
