Abstract

PURPOSE: To increase humidity resistance, by irradiating B or P ions on the outer surface of an organic, insulating film which has been heat-solidified.
CONSTITUTION: A semiconductor base plate on which a PN junction has been formed is coated with polymide-isoindolo-quinazolinedione film 9. After this, it is given heat treatment at 200°C for 60 min and is heat solidified. Then, it is etched by hydrazine hydrate+ehylenediamine. Next, by irradiating B ions, 1012/cm3, at 10 KV, the outer surface of film 9 is super-solidified (10). By selecting the kind of charged particles, accelerating voltage, the amount of irradiation, it is possible to obtain a super-solidified film of the desired characteristics and thickness. By this, the film coating is made impenetrable by moisture. It is free from defect, has excellent coating characteristics and proper elasticity, and improves the reliability of semiconductor device.
