- 4. A semiconductor package comprising:
- a cap for hermetically sealing said package;
- a bottom portion having leads and comprising an adhering surface to which said cap may be adhered without interposing said leads therebetween, and a plurality of guides each having the form of a lug, wherein one guide is positioned at each corner of said adhering surface,
