    摘要: A method of modifying a layer of thin film composite material to achieve one or more desired properties for the thin film layer which cannot be achieved by heat treatment at all practical temperatures of operation allowable by particular integrated circuit processes. In particular, the thin film composite material is subjected to an ion implantation process. Depending on the doping species, the doping concentration, the doping energy, and other ion implantation parameters, one or more properties of the deposited thin film resistive layer can be modified. Such properties may include electrical, optical, thermal and physical properties. For instance, the sheet resistance and/or the temperature coefficient of resistance of the thin film composite material may be increased or decreased by appropriately implanting ions into the material. The ion implantation can be applied globally in order to modify one or more properties of the entire deposited thin film composite layer. Alternatively, the ion implantation can be applied regionally in order to modify the thin film composite material at a first region, not modify the thin film composite material at a second region, and/or modify the thin film composite material in another way at a third region.

    摘要: In a method and apparatus for plasma stripping a polymer photoresist coating from a semiconductor substrate, positively charged species are removed from an activated gas flow before the gas flow is brought into contact with the coating to strip the coating from the substrate. The positively charged species may be removed by bringing the activated gas into contact with a grounded conducting surface to discharge the positively charged species, or by passing the activated gas through a negatively charged electrostatic filter to filter out positively charged species. The removal of positively charged species from the gas flow reduces or eliminates build up of positive charge on an outer surface of the photoresist coating so as to avoid driving mobile positively charged ions from the photoresist into the substrate, thereby avoiding contamination of the substrate.

    摘要: In a method and apparatus for plasma stripping a polymer photoresist coating from a semiconductor substrate, ultraviolet radiation generated as a byproduct of plasma generation is absorbed by a baffle placed between a plasma source and the substrate. The baffle inhibits incidence of ultraviolet light on the substrate while permitting flow of activated gas onto the substrate to chemically strip the photoresist from the substrate. Use of the baffle reduces microscopic damage to the substrate.

    摘要: A new and improved method of forming a thin film resistor is provided herein that overcomes many of the drawbacks of prior art methods. More specifically, the new method of forming a thin film provides for a well-controlled dielectric thickness under the thin film resistor which is useful for laser trimming purpose. The preferred thickness of the dielectric layer is an integer of a quarter wavelength of the optical energy used to laser trim the resistor. The new method also provides contacts to the thin film resistor that do not directly contact the thin film resistor so as to prevent any adverse process effects to the thin film resistor. More specifically, the method of forming a thin film resistor includes the steps of forming a pair of spaced-apart polysilicon islands over a semiconductor substrate, forming a dielectric layer over and between the polysilicon islands, forming contact holes through the dielectric layer to expose respective first regions of the polysilicon islands, forming a layer of thin film resistive material that extends between respective first regions of the polysilicon islands, forming another dielectric layer over the polysilicon islands and over the thin film resistive material layer, and forming metal contacts through the second dielectric layer in a manner that they make contact to respective second regions of the polysilicon islands, wherein the first and second regions of the polysilicon islands are different.

    摘要: In a method for the formation of an isolating oxide layer on a silicon substrate, an anti-nitridation layer is formed on a silicon substrate at locations where isolating oxide is desired. The anti-nitridation layer has openings therethrough which expose the silicon substrate at locations where isolating oxide is not desired. A thin silicon nitride layer is selectively grown at the locations where isolating oxide is not desired by nitridation of the exposed silicon substrate. Isolating oxide is then selectively grown at the locations where isolating oxide is desired. The thin silicon nitride layer inhibits oxide growth at the locations where isolating oxide is not desired. The method reduces "bird's beak" formation and is particularly applicable to high density IGFET devices.

    摘要: This invention relates to the design of apparatus for processing electronic devices, including equipment for chemical vapor deposition or transport polymerization. The new designs of gas separator plates, their configuration, and the regulation of gas flows through the system provides control over the pattern of precursor gas flow away from the separation plates, thereby decreasing the amount of byproducts that are deposited on the plates and throughout the reactor. New designs for shaping other surfaces of the dispersion head reduces contamination of those elements, and new designs for chamber panels decrease the deposition of byproducts on those surfaces, as well as other elements of the reactor. Decreasing deposition of byproducts increases the amount and the quality of the film that can be deposited without requiring the system to be shut down for cleaning. This increases the throughput of products in the deposition process, thereby increasing the efficiency of electronic device manufacture and lowering the cost.

    摘要: A method is provided for forming a fully planarized trench isolated region in a semiconductor substrate for an integrated circuit, for example, a trench isolated field oxide region, or a trench isolated semiconductor region in which thin film semiconductor devices are formed. Planarization is accomplished by a chemical mechanical polishing process in which coplanar layers of a chemical mechanical polish resistant material are provided in a centre region of wide trenches as well as on the semiconductor substrate surface adjacent the trenches. The chemical mechanical polish resistant layer in the centre region of a wide trench forms an etch stop to prevent dishing of layers filling the trench during overall wafer planarization by chemical mechanical polishing. The method is compatible with CMOS, Bipolar and Bipolar CMOS processes for submicron VLSI and ULSI integrated circuit structures.
