base region 14 of Huang (Fig. 12). Indeed, Huang (col. 2, ll. 3-
6) alternatively refers to base region 14 as “the channel
region.”
Appellants, on the other hand, argue that the examiner’s
definition is overly broad, and that only the part of P type base
region 14 of Huang that is directly beneath gate structure 26 can
be considered a channel region. Under this scenario, Huang does
not satisfy the requirement of claim 14 that a p-type buried body
diffusion, i.e., the P+ buried layer 35 of Huang, “underlies said
channel.”
To support their position, appellants rely on Sze. However,
as instructive as Sze may be, we find nothing in Sze which
specifically indicates that when a surface inversion layer (or
channel) forms, it is limited only to the area or region directly
beneath the gate structure. Nor have appellants explained how
this concept necessarily follows from the Sze text.
Neither do we find anything in appellants’ specification
which so specifically defines or limits the boundaries of the
channel region. Nor do appellants offer any explanation as to
how their construction of the claim terminology in question
necessarily follows from the specification.
