Abstract: A laser pattern inspection and/or writing system which writes or inspects a pattern on a target on a stage, by raster scanning the target pixels. Inspection can also be done by substage illumination with non-laser light. A database, organized into frames and strips, represents an ideal pattern as one or more polygons. Each polygon's data description is contained within a single data frame. The database is transformed into a turnpoint polygon representation, then a left and right vector representation, then an addressed pixel representation, then a bit-mapped representation of the entire target. Most of the transformations are carried out in parallel pipelines. Guardbands around polygon sides are used for error filtering during inspection. Guardbands are polygons, and frames containing only guardband information are sent down dedicated pipelines. Error filtering also is done at the time of pixel comparisons of ideal with real patterns, and subsequently during defect area consolidation. Defect areas are viewed as color overlays of ideal and actual target areas, from data generated during real time. Defect areas can be de-zoomed to allow larger target areas to be viewed. An autofocus keeps the scanning laser beam in focus on the target. The inspection system is used to find fiducial marks to orient the target prior to raster scanning. IC bars are provided with alignment marks for locating each IC bar. Interferometers or glass scale encoders allow the stage position to be known.

Abstract: Heat activated method for developing and improving the definition of a patterned heat-photoresist layer as applied to a substrate surface of different material, such as a semiconductor slice, in the fabrication of an electronic structure or photomask, through the use of a reactive species of oxygen including monatomic oxygen or ozone in an oxygen-containing gas. A layer of photoresist material upon being selectively exposed to an energy source, such as ultraviolet radiation, X-ray, or E-beam radiation acquires a predetermined patterned definition therein because of chemical changes in the photoresist material which is photosensitive. After such selective exposure, the photoresist layer is characterized by a differential reactivity which is heightened by a chemical or a physical change occurring in either one of the exposed or unexposed portions of the layer of photoresist material enabling the selective removal thereof. In a preferred embodiment, the photoresist material is of a character undergoing a reduction in thickness in areas unexposed to the energy source which may be accentuated by a further heat treatment to produce regions of reduced thickness in the photoresist layer corresponding to the desired pattern. The regions of photoresist material of reduced thickness are then selectively removed from the layer of photoresist material by the differential reaction of the gaseous reactive oxygen species therewith to develop the pattern in the layer of photoresist material as defined by its selective exposure to the energy source.

Abstract: Optical illumination rather than furnace heating is used to drive in MOSFET source and drain diffusions, preferably using a surface layer of antimony as the dopant source. This results in substantially less overlap between the gate and the source and drain diffusions. Similarly, if the present invention is practiced in a process having gate sidewalls less than zero overlap can be achieved.

Abstract: A method for selectively depositing a composite material over high-thermal-conductivity areas (such as silicon) and not over low-thermal-conductivity areas (such as oxide), which does not require any additional patterning step. A composite material, such as TiW is deposited overall by sputtering. A short pulse of light is then applied, and the composite material over the oxide separates and flakes off, while the composite material over the high-thermal-conductivity area remains in place.

Abstract: A row of light emitting diodes approximately one inch apart are mounted along the edge of a spreading table. A small computer reads a cut file which specifies (among other items) the splice zone locations. The computer then controls the lighting of appropriate LEDs to define the beginning and ending of these splice zones. Locations between the LEDs may be identified by lighting LEDs on either side of the appropriate location.

Abstract: The present invention discloses a method for planarizing contact holes, vias, and other surface depressions, during the fabrication of an integrated circuit structure. Differential thermal conductivities are exploited to selectively remove a deposited film of metal from high-thermal-resistance areas, such as silicon dioxide or other insulators, and not from low-thermal-resistance areas, such as silicon or metal. By repetition of this step, very deep depressions, having a high aspect ratio, are reliably filled.
