摘要:
A method for making a semiconductor device comprises forming an electrical interconnect layer, forming a first dielectric layer over the interconnect layer, forming an opening in the first dielectric layer over a first electrical interconnect of the interconnect layer, forming an aluminum layer over the first dielectric layer, etching the aluminum layer to form an aluminum die pad, forming a second dielectric layer over the aluminum die pad and the first dielectric layer, and forming a conductive via through the first and second dielectric layers to contact a second electrical interconnect of the interconnect layer.
摘要:
In a making a semiconductor device, a patterning stack above a conductive material that is to be etched has a patterned photoresist layer that is used to pattern an underlying a tetraethyl-ortho-silicate (TEOS) layer. The TEOS layer is deposited at a lower temperature than is conventional. The low temperature TEOS layer is over an organic anti-reflective coating (ARC) that is over the conductive layer. The low temperature TEOS layer provides adhesion between the organic ARC and the photoresist, has low defectivity, operates as a hard mask, and serves as a phase shift layer that helps, in combination with the organic ARC, to reduce undesired reflection.

A method for imparting stress to the channel region of a transistor is provided. In accordance with the method, a semiconductor layer (307) is provided which has a dielectric layer (305) disposed beneath it. A trench (319) is created which extends through the semiconductor layer and into the dielectric layer, and the trench is backfilled with a stressor material (320), thereby forming a trench isolation structure. A channel region (326) is defined in the semiconductor layer adjacent to the trench isolation structure.
