Comments: SEM Image Dots for Nancy 7/22/08 User: Date: Sample ID: Sample Description: Location on Wafer:* * All orientations given assuming the flat of the wafer is down, or facing you Comments: Lili Hsu 7/25/08 7/22/08 Etched, no photoresist DEEP 10 min Center The sides of all these dots are straighter than they appear in the pictures. A combination of the angle of the wafer and a very slow slide (due possible to the wafer slowly charging up?) makes the dots look shorter and the sides more tapered than they acutally are.
