Patent ID: 8524537

Claim:
A method of making a semiconductor device, comprising: providing a semiconductor wafer including a plurality of semiconductor die separated by a saw street; forming a build-up interconnect structure over a first surface of the semiconductor wafer; forming a first insulating layer over the build-up interconnect structure; forming a plurality of bumps over the build-up interconnect structure; depositing a protective coating material over the first insulating layer and the saw street; applying a lamination tape over the protective coating material and the bumps; removing a portion of a second surface of the semiconductor wafer opposite the first surface of the semiconductor wafer; removing the lamination tape while leaving the protective coating material over the first insulating layer and the saw street; forming a first channel through the saw street extending through the build-up interconnect structure and partially but not completely through the semiconductor wafer after removing the lamination tape; and removing the protective coating material after forming the first channel.
