Abstract:
1. A method of fabricating a semiconductor device, the method comprising: coating a photosensitive material over the device; positioning at least one reticle, which has a dimension, at a plurality of reticle locations over the photosensitive material according to a sequence to form a plurality of masks, respectfully; for each reticle location in the sequence, selectively exposing the photosensitive material underlying the reticle to electromagnetic radiation; using a developer to develop the selectively exposed photosensitive material to provide a photoresist pattern which is made up of the plurality of masks that collectively encompass a chip area of the device, wherein the plurality of masks touch one another at their respective edges, and wherein the chip area has a dimension larger than the dimension of the at least one reticle; and applying a chemical treatment to the photoresist pattern to selectively etch or deposit a conductive layer over or within the device in accordance with the photoresist pattern, wherein the selectively etched or deposited conductive layer includes a plurality of regions corresponding to the plurality of masks, and wherein the plurality of regions are electrically coupled to each other.
