First test of KOH etching of <110> Si with metal hardmask (die 5J3). 20μm half-pitch, 400x mag.

 
Nyanotechnology! This nyan cat is etched into a 200nm thick copper film and is around 600μm from head to tail.

Chip #5I4 (20 μm half-pitch lines in evaporated copper over Cr adhesion layer on silicon) seen at 170x magnification.

Chip #5I4 seen at 1000x magnification. Light areas are copper, dark are silicon, medium are incompletely etched chromium.
