摘要： An embodiment of the disclosure includes a method of pitch reduction. A substrate is provided. A first material layer is formed over the substrate. A second material layer is formed on the first material layer. A hardmask layer is formed on the second material layer. A first imaging layer is formed on the hardmask layer. The first imaging layer is patterned to form a plurality of first features over the hardmask layer. The hardmask layer is etched utilizing the first imaging layer as a mask to form the first features in the hardmask layer. The first imaging layer is removed to expose the etched hardmask layer and a portion of a top surface of the second material layer. A second imaging layer is formed and the process is repeated, such that first and second features are alternating with a pitch substantially half the original pitch.

摘要： A semiconductor device is formed by a multi-step etching process that produces trench openings in a silicon substrate immediately adjacent transistor gate structures formed over the substrate surface. The multi-step etching process is a Br-based etching operation with one step including nitrogen and a further step deficient of nitrogen. The etching process does not attack the transistor structure and forms the openings. The openings are bounded by upper surfaces that extend downwardly from the substrate surface and are substantially vertical, and lower surfaces that bulge outwardly from the upper vertical sections and undercut the transistor structure. The openings may be filled with a suitable source/drain material to produce SSD transistors with desirable Idsat characteristics.

摘要： A method of forming a hardmask for defining shallow trench isolation regions in a semiconductor substrate layer includes the steps of: depositing a hardmask layer over the semiconductor substrate layer; depositing and patterning a first photoresist layer over the hardmask layer; etching the hardmask layer after patterning the first photoresist layer to form an interim hardmask layer having at least one line feature; depositing and patterning a second photoresist layer over the interim hardmask layer; and forming a hardmask, the forming step including etching the interim hardmask layer after patterning the second photoresist layer to define a line end of the at least one line feature.

摘要： A multi-step etching process produces trench openings in a silicon substrate that are immediately adjacent transistor structures formed over the substrate surface. The multi-step etching process is a Br-based etching operation with one step including nitrogen and a further step deficient of nitrogen. The etching process does not attack the transistor structure and forms an opening bounded by upper surfaces that extend downwardly from the substrate surface and are substantially vertical, and lower surfaces that bulge outwardly from the upper vertical sections and undercut the transistor structure. The aggressive undercut produces a desirable stress in the etched silicon surface. The openings are then filled with a suitable source/drain material and SSD transistors with desirable Idsat characteristics may then be formed.
