Defects on or in silicon wafers may adversely affect device performance and yield. Crystal defect analysis is a useful technique in troubleshooting device process problems. The type, location, and density of defects counted by this Test Method may be related to the crystal growth process, surface preparation, contamination, or thermal history of the wafer. This Test Method is suitable for acceptance testing when used with referenced standards. This Test Method describes the technique to count the density of surface defects in silicon wafers by microscopic analysis. Application of this Test Method is limited to specimens that have discrete, identifiable artifacts on the surface of the silicon sample. Typical samples have been preferentially etched according to SEMI MF1809 or epitaxially deposited, forming defects in a silicon layer structure. Wafer thickness and diameter for this Test Method is

Application of this Test Method is limited to specimens
that have discrete, identifiable artifacts on the surface of the silicon
sample. Typical samples have been preferentially etched according to SEMI
MF1809 or epitaxially deposited, forming defects in a silicon layer structure.
Wafer thickness and diameter for this Test Method is
limited only by the range of microscope stage motions available.
This Test Method is applicable to silicon wafers with
defect density between 0.01 and 10,000 defects per cm2.
