摘要： An improved alignment methodology for lithography. In the method, a third level is aligned to two previous levels, where the alignment mark location for the third level is calculated based upon the two previous levels in both the x- and y-directions. A preferred embodiment of the invention relates to a lithography alignment method for aligning a third level of a semiconductor device relative to first and second previous levels of the device. The method comprises the steps of forming first and second patterns at the first and second levels respectively, and determining offsets of the first and second patterns in two orthoginal directions. An optimum location for a third pattern in the third level is then determined based on an average of the offsets of the first and second patterns.

摘要： A memory cell in an integrated circuit is fabricated in part by forming a lower electrode feature, an island, a sacrificial feature, a gate feature, and a phase change feature. The island is formed on the lower electrode feature and has one or more sidewalls. It comprises a lower doped feature, a middle doped feature formed above the lower doped feature, and an upper doped feature formed above the middle doped feature. The sacrificial feature is formed above the island, while the gate feature is formed along each sidewall of the island. The gate feature overlies at least a portion of the middle doped feature of the island and is operative to control an electrical resistance therein. Finally, the phase feature is formed above the island at least in part by replacing at least a portion of the sacrificial feature with a phase change material. The phase change material is operative to switch between lower and higher electrical resistance states in response to an application of an electrical signal.

摘要： Methods for fabricating a semiconductor device include forming a first layer on an underlying layer, forming a hardmask on the first layer, and patterning holes through the hardmask and first layer. An overhang is formed extending over sides of the holes. A conformal layer is deposited over the overhang and in the holes until the conformal layer closes off the holes to form a void/seam in each hole. The void/seam in each hole is exposed by etching back a top surface. The void/seam in each hole is extended to the underlying layer.

摘要： A semi-conductor device includes a silicon substrate. A gate oxide dielectric layer is on the silicon substrate. A gate conductor includes a relatively thin layer of germanium on the dielectric layer. A relatively thick layer of gate conductor material is provided on the layer of germanium. Incorporating germanium at the gate conductor interface with the gate oxide stabilizes the gate oxide by providing a means of drawing charge trapping sites away from the oxide.
