摘要: A method is disclosed for forming a semiconductor structure with conductive features having reduced dimensional spacing or pitch. First polymer layers are formed over photoresist features to facilitate patterning of both an underlying first dielectric and conductive layer into first dielectric features and conductive features. Second dielectric features are then formed in spaces between the first dielectric and between the conductive features, followed by the first dielectric features being removed. Second polymer layers are then formed over the second dielectric features, such that portions of the second polymer layers cover corresponding portions of the conductive features that are adjacent to the second dielectric features. Subsequently, the second polymer layers are used to pattern the conductive features, to thereby remove portions of the conductive features that are not covered by the polymer layers and define second conductive features. The first and second polymer layers can be formed using dielectric resolution enhancement coating techniques.

摘要: A method for forming an integrated circuit includes forming a first dielectric layer over a gate electrode of a transistor. An etch-stop layer is formed over the first dielectric layer. An opening is formed through the first dielectric layer and the etch-stop layer, exposing a source/drain (S/D) region of the transistor. A metal layer is formed in the opening, contacting the S/D region of the transistor. The metal layer has a surface that is at least partially substantially level with a first top surface of the etch-stop layer. A damascene structure is formed and coupled with the metal layer.

摘要: A three-dimensional memory structure and manufacturing method thereof is provided. A first stack layer is formed over a substrate. The first stack layer includes, from the substrate upwards, an n-type polysilicon layer, a conductive layer, an anti-fuse and another n-type polysilicon layer. The first stack layer is patterned to form a first stack circuit. Thereafter, a second stack layer is formed over the first stack circuit. The second stack layer includes, from the first stack circuit upwards, a p-type polysilicon layer, a conductive layer, an anti-fuse and another p-type polysilicon. The second stack layer is patterned to form a second stack circuit that crosses over the first stack circuit perpendicularly. The aforementioned steps are repeated to form more stack circuits above the substrate and hence produce a three-dimensional structure.

摘要: A method for forming vias and trenches for an interconnect structure on a substrate includes exposing via pitch reduction patterns in a photoresist layer, developing the patterns to remove the via pitch reduction patterns, etching the photoresist layer partially using a polymer gas to reshape the pattern into small via shapes, and etching the remaining photoresist layer to extend the reshaped pattern. The reshaped small via shape patterns have a smaller pitch than the via pitch reduction patterns in a long direction. For via pitch reduction patterns having two vias each, the pattern has a peanut-shape. During the reshaping etch operation, the polymer gas deposits more in a pinched-in middle section while allowing downward etch in unpinched sections.
