IPC: H01L21/306
Filed: 2004-01-14
Abstract: <P>PROBLEM TO BE SOLVED: To provide a semiconductor wafer processing method whereby a high degree of flatness is achieved for the wafer surfaces and whereby pollution by heavy metals, such as iron, nickel, chromium, and copper is prevented.  <P>SOLUTION: An etching step S1 is implemented wherein a wafer after the lapping step is etched with an alkaline solution, and then an acid cleaning step S2 is implemented wherein the wafer is washed with an acid solution for the removal of heavy metal impurities that the wafer collects in the etching step S1. The use of alkaline etching enables etching to be accomplished with a high degree of flatness achieved on the wafer top surface, and the use of acid cleaning after etching prevents the wafer top surface from heavy metal pollution. Further, a rear surface polishing step S3 is implemented after acid cleaning, and this raises the yield of devices by improving in the degree of flatness to be achieved in a top surface polishing step S4 and by suppressing the rise of dust due to wafer rear surface chipping.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
