Those one round and slot holes is for manufacturing process, simply
drops onto bed with two precision-machined pins to keep things in
alignment. This is especially necessary because chip bonding and
wire bonding, lid placing and soldering process is mostly mechanical.

Later on when processing becomes powerful enough for optical
alignment on the fly, that holes disappeared.
