    摘要: A patterning method of the present invention is described as follows. A mask layer and a patterned photoresist layer are formed on a target layer in sequence, wherein an etching rate of the mask layer is different from an etching rate of the target layer. A plurality of spacers is formed on sidewalls of the patterned photoresist layer respectively, wherein an etching rate of the spacers is different from the etching rate of the mask layer. The patterned photoresist layer is removed to form an opening between any two adjacent spacers. A portion of the mask layer is removed by using the spacers as a mask so as to form a patterned mask layer. A portion of the target layer is removed by using the patterned mask layer as a mask.

    摘要: A method for controlling an ADI-AEI CD difference ratio of openings having different sizes is described. The openings are formed through a silicon-containing material layer, an etching resistive layer and a target material layer in turn. Before the opening etching steps, at least one of the opening patterns in the photoresist mask is altered in size through photoresist trimming or deposition of a substantially conformal polymer layer. A first etching step forming thicker polymer on the sidewall of the wider opening pattern is performed to form a patterned Si-containing material layer. A second etching step is performed to remove exposed portions of the etching resistive layer and the target material layer. At least one parameter among the parameters of the photoresist trimming or polymer layer deposition step and the etching parameters of the first etching step is controlled to obtain a predetermined ADI-AEI CD difference ratio.

    摘要: A method of removing a spacer, a method of manufacturing a metal-oxide-semiconductor transistor device, and a metal-oxide-semiconductor transistor device, in which, before the spacer is removed, a protective layer is deposited on a spacer and on a material layer (such as a salicide layer) formed on the source/drain region and a gate electrode, such that the thickness of the protective layer on the spacer is smaller than the thickness on the material layer, and thereafter, the protective layer is partially removed such that the thickness of the protective layer on the spacer is approximately zero and a portion of the protective layer is remained on the material layer. Accordingly, when the spacer is removed, the material layer may be protected by the protective layer.

    摘要: Automatic process control of after-etch-inspection critical dimension. A dielectric layer is deposited over a substrate and is then planarized to a first thickness. A cap oxide layer having a second thickness is deposited, wherein the combination of the first thickness and the second thickness is substantially constant. An ADI CD of a contact hole to be formed on the substrate is altered and pre-determined based on the second thickness of the cap oxide layer. A photoresist layer is formed on the cap oxide layer. An opening having the predetermined ADI CD is formed in the photoresist layer. Using the photoresist layer as an etching mask, the cap oxide layer and the dielectric layer is etched through the opening to form a contact hole having an AEI CD.
