Abstract:
A method of connecting a first layer of a semiconductor device and a second layer of the semiconductor device, the second layer at least partially overlapping at least a portion of the first layer, comprising:applying photoresist to an insulating layer of the semiconductor device disposed adjacent the first layer;exposing photoresist over a first area of the semiconductor device to a first dosage of radiation;exposing photoresist over a second area of the semiconductor device, adjacent the first area, to a second dosage of radiation;developing said photoresist to concurrently remove photoresist over the first area to a first depth of the photoresist and to remove photoresist over the second area so as to expose the insulating layer at least partially through the photoresist in the second area;removing a region of the insulating layer at the second area to expose the first layer through the insulating layer; anddisposing conductive material adjacent a portion of the first layer exposed through the insulating layer.
