Abstract:
1. A photomask comprising: a base having a first surface and an opposite second surface and fabricated from an electrically non-conductive material; a light shielding pattern fabricated from metal material and disposed on and adhering to the first surface of the base; a plurality of chip pattern regions formed on the light shielding pattern; scribe regions defined between the chip pattern regions, the scribe regions being defined by using the light shielding pattern; and slits formed into and through the light shielding pattern and to the first surface of the base to define electrically-isolated chip pattern region areas, the slits surrounding the electrically-isolated chip pattern region areas to electrically isolate the electrically-isolated chip pattern region areas from either a remaining portion of the light shielding pattern disposed outside of the electrically-isolated chip pattern region areas or adjacent ones of other electrically-isolated chip pattern region areas.
