    摘要: One aspect of the invention relates to flash memory device that stores charge in a substantially stoichiometric silicon oxynitride dielectric. A stoichiometric silicon oxynitride dielectric can be represented by the formula (Si3N4)x(SiO2)(1-x), where x is from 0-1. A substantially stoichiometric silicon oxynitride dielectric has relatively few atoms that do not fit into the foregoing formula. The flash memory devices of the present invention have fewer defects and lower leakage than comparable SONOS-type flash memory devices. Another aspect of the invention relates to assessing the stoichiometry by FTIR, refractive index measurement, or a combination of the two.

    摘要: A semiconductor isolation material deposition system and method that facilitates convenient and efficient integrated multi-step deposition of isolation regions is presented. In one embodiment of the present invention, an integrated circuit includes densely configured component areas and sparsely configured component areas. An active area in a wafer is created and a shallow trench space is formed. A thin layer of TEOS isolation material layer is deposited on top of the active area and the shallow trench. For example, the layer of thin layer of TEOS isolation material is in a range of 4000 to 5000 angstroms thick over the top of underlying active areas. A reverse mask and pre-planarization etch is performed on the thin layer of TEOS isolation material. The remaining TEOS edge spikes between the densely configured component area and the sparsely configured component area are minimal (e.g., about 500 angstroms. The remaining excess oxidant and silicon nitride are removed utilizing chemical mechanical polishing processes. In one exemplary implementation, the present invention facilitates an integrated approach to STI fabrication processes that achieve successful high yielding results by considering the impacts of one process step on another.

    摘要: A method of semiconductor integrated circuit fabrication. Specifically, one embodiment of the present invention discloses a method for reducing shallow trench isolation (STI) corner recess of silicon in order to reduce STI edge thinning for peripheral thin gate transistor devices 480 in an integrated circuit 400 comprising flash memory devices 380, and both thick 390 and thin 480 gate transistor devices. The method begins by forming a tunnel oxide layer 310 over a semiconductor substrate 430 for the formation of the flash memory devices 380 (step 220). A mask 350 is formed over the thin gate transistor devices 480 to inhibit formation of a thick gate oxide layer 360 for the formation of the thick gate transistor devices 390 (step 230). The mask 350 reduces shallow trench isolation (STI) recess by eliminating removal of the thick gate oxide layer 360 before forming a thin oxide layer 410 for the thin gate transistor devices 480.

    摘要: A method of semiconductor integrated circuit fabrication. Specifically, one embodiment of the present invention discloses a method for reducing shallow trench isolation (STI) corner recess of silicon in order to reduce STI edge thinning on tunnel oxides (510) for flash memories (devices M and N). An STI process is implemented to isolate flash memory devices (devices M and N) in the semiconductor structure (200). In the STI process, a nitride layer (210) is deposited over a silicon substrate (280). An STI region (290) is formed defining STI corners (240) where a top surface (270) of the silicon substrate (280) and the STI region (290) converge. The STI region (290) is filled with an STI field oxide and planarized until reaching the nitride layer (210). A local oxidation of silicon (LOCOS) is then performed to oxidize the top surface (270) of the silicon substrate adjacent to the STI corners (240). Oxidized silicon is grown to boost the thickness of a later formed tunnel oxide layer (510) at the STI corners (240).

    摘要: A non-volatile memory device includes an array of non-volatile memory cells. When programming the memory cells, a voltage supply source is used that includes multiple independent charge pumps. The independent charge pumps supply the programming voltage to different ones of bit lines in the array of memory cells. Using multiple charge pumps tends to reduce output voltage fluctuations and thereby reduce power loss.

    摘要: Techniques for programming a non-volatile memory device, such as a Flash memory, include floating source lines of memory cells based on a data pattern that is being programmed to the memory device. The source lines to float are selected such that a distance between drain bit lines and source bit lines of different memory cells in a row is maximized. In this manner, leakage current between these drain bit lines and source bit lines can be decreased.
