    摘要: A method and apparatus for dispensing a liquid etchant onto a wafer dispenses the liquid etchant onto a wafer using a scanning dispensing nozzle while controlling the dispensing temperature of the etchant in real time as a function of the radial position of the dispensing nozzle over the wafer. The dispensing temperature of the etchant is controlled to enhance the effectiveness of the etchant and thus compensate for the lower etching rate zones in the wafer.

    摘要: A method for fabricating a strained-silicon semiconductor device to ameliorate undesirable variation in selectively grown epitaxial film thickness. The layout or component configuration for the proposed semiconductor device is evaluated to determine areas of relatively light or dense population in order to determine whether local-loading-effect defects are likely to occur. If a possibility of such defects occurring exists, a dummy pattern of epitaxial structures may be indicated. If so, the dummy pattern appropriate to the proposed layout is created, incorporated into the mask design, and then implemented on the substrate along with the originally-proposed component configuration.

    摘要: A method for forming a field effect transistor device employs a self-aligned etching of a semiconductor substrate to form a recessed channel region in conjunction with a pair of raised source/drain regions. The method also provides for forming and thermally annealing the pair of source/drain regions prior to forming a pair of lightly doped extension regions within the field effect transistor device. In accord with the foregoing features, the field effect transistor device is fabricated with enhanced performance.
