In a semiconductor device having a semiconductor die without an ESD circuit and
a separate ESD circuit and an external lead, the external lead is first bonded
to the separate ESD circuit. Thereafter, the separate ESD circuit is bonded to
the semiconductor die. As a result, in the process of bonding the semiconductor
die, any ESD disturbance is absorbed by the ESD circuit. In addition, a semiconductor
device such as a DDR DRAM memory device, has a chip carrier with a first surface
having a plurality of leads and a second surface opposite to it with an aperture
between them. A semiconductor die with a mounting surface and a bonding pad faces
the second surface with the bonding pad in the aperture. An ESD circuit is mounted
on the mounting surface in the aperture. A first electrical connector connects
one of a plurality of leads to the ESD circuit and a second electrical connector
connects the ESD circuit to the bonding pad.
