Appeal No. 95-3348
Application 07/944,967
one main die pad (15) with a supporting lead (3); and
two or three auxiliary die pads (13, 14 or 16) with
supporting leads (3', 3'', or 3'''), separate from and
disposed on opposite sides of the main die pad (15),
each extending inwardly from an opposite direction from
the frame.
We find several errors and deficiencies in the examiner's
analysis. In Shiga's Figure 1(E), all of the four die pads in
the middle of the lead frame are connected. It cannot be
reasonably said that there are two auxiliary die pads separate
from a main die pad. Even if we consider the die pads of Shiga's
Figure 1(E) as separate, the Figure discloses nothing more than
Shiga's Figure 1(B) which has other deficiencies. The die pads
shown in Shiga's Figure 1(B) have supporting leads which are
evidently connected to the four corners of a lead frame. Thus,
it cannot be said that the supporting leads for the main die pad,
whichever one pad is denominated as the main die pad, are
connected to a first side, and that the supporting leads for two
auxiliary die pads, whichever two pads are denominated as
auxiliary die pads, are connected to a second side opposite the
first side.
In any event, not all pads in Shiga's Figure 1(B) may
constitute auxiliary die pads disposed on opposite sides of the
main die pad. In our view, an adjacent die pad and a diagonally
opposed die pad are not on opposite sides of the main die pad.
