SEMICONDUCTOR DEVICE AND METHOD FOR MANUFACTURING THE SAME

摘要

A semiconductor device capable of securing excellent tolerance to moisture and high mechanical strength and a method for manufacturing the same are obtained. A field effect transistor (2) is formed on the main surface of a substrate (1). Next, a low melting point glass layer (5) which has a melting point of 450°C or less is coated on the main surface of the substrate (1) and the field effect transistor (2). Then the substrate (1) is heat-treated while an insulating or semi-insulating pressurization fixture (6) pressurizes the low melting point glass layer (5) toward the main surface of the substrate (1), to sinter the melting point glass layer (5). After the low melting point glass layer (5) is sintered, the pressurization fixture (6) is left as it is.
