    摘要: A scaleable laser and control unit (58) is used to differentially heat portions of a semiconductor substrate (40) during downstream etching. Such differential heating provides a differential etch rate for each portion heated resulting in improved uniformity and reduced etch induced surface damage. An etching chamber (50) capable of containing the downstream plasma and providing a direct line of sight between the substrate (40) and the scanable laser unit (58) is provided. In addition, the system provides for dynamic updating of the process by in situ etch rate and temperature measurements.

    摘要: A phase shift mask (24) used for manufacturing semiconductor devices includes a pattern layer (26) that contains the predetermined pattern of a desired semiconductor feature which is formed in a plurality of apertures in the pattern layer (26). A conformal coating (27) is applied to the mask (24) to create a phase shift region (31, 36, 37) within a predetermined distance (29) of each aperture in the pattern layer (26). The conformal coating (27) forms two regions (31, 36, 37) (32) having different thicknesses. The phase of light passing through the thicker or phase shift region (31, 36, 37) is shifted relative to light passing through the thin region (32).
