The claims stand rejected under 35 U.S.C. § 103 as follows:

OPINION
We reverse the aforementioned rejections. We need to
address only the independent claims, i.e., claims 29, 39 and 44.
Each of the independent claims requires a conductive layer
and an insulating layer overlying the conductive layer, wherein
the insulating layer has therein an opening having a lower
portion and a larger-diameter upper portion. In claim 29 the
lower portion has generally straight side walls extending
