摘要:
A method of preventing the formation of cracks on the backside of a silicon (Si) semiconductor chip or wafer during the processing thereof. Also provided is a method for inhibiting the propagation of cracks, which have already formed in the backside of a silicon chip during the processing thereof and prior to the joining thereto of a substrate during the fabrication of an electronic package. The methods entail either treating the backside with a wet etch, or alternatively, applying a protective film layer thereon prior to forming an electronic package incorporating the chip or wafer.
