I have a wafer of microprocessor chips (circa 1995) that failed inspection. It was given to me to use in lectures on computer technology.
The wafer is 8.0 inches in diameter and each microprocessor chip is approximately 0.5 inches on a side. The wafer contains several hundred microprocessor chips.
Feature sizes for this microprocessor ranged from 0.6 microns in its early days, to 0.35 microns in later versions. Over this interval, clock speeds ranged from 133 MHz t0o 200 MHz
D800E, ISO 200 (base), White Balance = Flash Nikon AFS Micro Nikkor 105 mm, G ED 1:2.8 at F/11.0
Two Nikon SB-R200 speedlights with diffusers were used on small, table top tripods to illuminate the wafer.
The top image is a full frame at the Micro Nikkor's closest focus.
The bottom image is a 100% crop from the center of the full frame image.
I see no sign of moire patterns in either of these images.
I continue to be impressed with the resolution capabilities of the D800E.
Please excuse the dust particles seen in the images. They refused to budge when I used my small Rocket blower, and I didn't want to us a brush on the wafer, and I didn't have time to clean it with alcohol.
Edited to correct typo and to mention that the original image was captured in uncompressed RAW, at 14 bit color depth. Image out of camera was about 74 MB, on screen following RAW 207 MB.
Comments and critique welcome.
