Abstract
A perpendicular write head having a wrap around shield and a conformal side gap. In fabricating the write head, the leading edge shield may be chemical mechanical polished down to a level that is substantially even with a chemical mechanical polishing stop layer. Because the leading edge shield and the chemical mechanical polishing stop layer are used as RIE stop for trench RIE, a fully conformal side shield may be formed with a LTE/LES.
