AN EPROM DEVICE AND METHOD OF MANUFACTURING SAME

摘要

An EPROM device includes a hollow cap having a head portion made of a material which passes UV rays therethrough and is installed on a lead frame covering an EPROM chip. An UV ray permeable resin fills at least a gap between the head portion of the hollow cap and a main surface of the EPROM chip. A first insulating resin fills the remaining portion of the interior space of the hollow cap, thereby forming with the UV ray permeable resin a double filling structure filling the interior of the cap.
