Title: Manufacturing method of semiconductor wafer
Inventor: SEKIYA KAZUMA
IPC: H01L21/301
Filed: 2002-12-20
Abstract: The subject of the invention is to fabricate a semiconductor wafer with sufficiently increased breaking strength, having no cut oblique layer, or having no cut bits and small pieces. For the semiconductor wafer W where plural circuits on the surface are divided by the dicing channels to form the individual semiconductor chip of each circuit, the surface side of the semiconductor wafer W is made to have the cutting remained portion 20. After forming the cut trench 19a on the backside of dicing channel without reaching the surface, by performing an etching process onto the backside to etch the cut trench side face and the cutting remained portion 20, each semiconductor chip is divided and formed so as to remove the cut oblique layer and cut bits and small pieces generated due to the cutting process.
