Abstract:
A method includes forming a polymer layer covering a metal via in a wafer, grooving the wafer to form a trench, wherein the trench extends from a top surface of the polymer layer into the wafer, and performing a die-saw on the wafer to separate the wafer into a plurality of device dies. A kerf passes through the trench. One of the device dies is placed over a carrier. An encapsulating material is dispensed over and around the device die. The method further includes pressing and curing the encapsulating material. After the encapsulating material is cured, a sidewall of the polymer layer is tilted. A planarization is performed on the encapsulating material until the polymer layer and the metal via are exposed. A redistribution line is formed over and electrically coupled to the metal via.

Claim (Index 19):
The method of  claim 16 , wherein the sidewall of the device die comprises:\n a first portion, with the first portion being a sidewall of a first polymer layer; and a second portion, with the second portion being a sidewall of a second polymer layer over the first polymer layer, wherein the second portion is more tilted than the first portion.
