Abstract: Apparatus for generating an image of objects in a three dimensional space for display on a two dimensional regular pixel array includes means (OFGN, SPGN) for anti-alias filtering which causes multiple rendition of the image with each rendition displaced by a sub-pixel offset (Nx,Ny) with respect to the previous rendition. Image primitives are rendered by a scan line algorithm using a linked active polygon list (APL) and a deleted polygon list (DPL) to enable vertical offsets to be effected. The deleted polygon list stores primitives which would not be effective for a given line but for the offset to enable anti-alias filtering. These polygons would not normally be available for processing when using the scan line algorithm. Economical hardware (600) is provided for horizontal edge correction of parameters such as depth (z) and texture coordinates (u,v).

Abstract: A precision resistor (11) is formed in an integrated circuit by a diffused region created at the same time as transistor source/drain regions (18, 24). In a CMOS process, this N-type resistor region is formed in an N-well (16), as is used for P-channel transistors. The resistor is formed using a deposited oxide layer (46) as a mask, and this oxide layer is also used to create sidewall spacers (24, 25) for the transistor gates. The sidewall spacers are used in creating self-aligned silicided areas (26, 27) over the source/drain regions, self-aligned with the gates, and the silicide is also used for contact areas (38) for the resistor. The value of the resistor is defined by the width of the deposited oxide layer left as a mask, but this does not require any critical alignment steps.

Abstract: A method of quantizing pixel values in an image formed by a plurality of pixels, each pixel representing an optical density of the image at a location within the image, and having an original optical density value selected from one of a set of 'c' original optical density values that has a number of members larger than a desired output set of 'd' optical density values through a process of combined halftoning and cell-to-cell error diffusion. Initially, each pixel is modified with a pro rata portion of an error term ε(n) determined for a previous halftone cell, or from the current cell in a previous interaction. A set of modified pixels, corresponding in position to an m x n halftone cell, are processed in accordance with a standard halftoning process, to derive a set of output pixels at one of d optical density levels. The calculated output density is used to address a lookup table (152) having a stored set of empirical density values upon printing the dot represented by a halftone cell with the same count of optical density levels. The empirical density value for the cell returned from the lookup table is compared to a sum of the modified pixel values for the cell. The difference (which represents the difference in gray level input and the actual output) is directed on a weighted basis to the pixels of subsequently processed dots.

Abstract: A system (60) and method for monitoring, evaluating and controlling the uniformity of a semiconductor wafer fabrication process is provided for use in manufacturing integrated circuits on semiconductor wafers (40). By using  in situ  ellipsometry (20) in conjunction with statistical modeling methods, the spatial etch rate pattern across a semiconductor wafer (40) may be inferred as a function of the process conditions. A predicted mean etch rate may be calculated for other locations (46 and 48) on the semiconductor wafer surface (42) by using the mean etch rate measured at the selected ellipsometer site (44) and individual spatial etch rate models developed for each site (44 and 48) based on statistically designed experiments. The predicted mean etch rate at the other sites (46 and 48) is also a function of the fabrication process conditions. The method for evaluating uniformity may be used with fabrication processes such as oxidation, doping, etching or any other process which may be measured  in situ  at a selected location (44) on a semiconductor wafer (40) during the fabrication process.
