A method includes forming a write pole layer having a front surface, a leading surface, a trailing surface and side surfaces connecting the leading surface to the trailing surface. The method also includes forming side shield layers proximate to the side surfaces of the write pole layer. A patterned sacrificial layer is deposited over the side shield layers, and a trailing surface bevel is formed on the write pole layer.
