Abstract
PURPOSE: To print a mark having high holding property on a resin surface of the portion to be marked in a resin sealed semiconductor device by marking the resin surface after grinding it to thereby eliminate surface cleaning process affecting adversely the reliability of the device.
CONSTITUTION: After sealing and hardening with resin material a semiconductor device such as MOSIC or the like by transfer forming or injection molding or the like, the resin surface of the device is ground by a sand paper process, a sandblasting process, a buff polishing process, etc. A mark is printed on the polished portion, and heated for drying it. Thus, the mark may not be erased even without cleaning it by trichloroethylene before marking for preventing the diminution of the mark to thereby eliminate the damage rate due to the mark in the semiconductor device.
