    摘要: Apparatus and methods for simultaneously supporting multiple workpieces inside a processing space of a plasma processing system for simultaneous two-sided plasma processing. The apparatus may be a fixture having a carrier plate configured to be supported inside the processing space and a plurality of first openings extending through the thickness of the carrier plate. The carrier plate is configured to contact each of the workpieces over an annular region at an outer peripheral edge so that the first and second sides of each of the workpieces is exposed to the plasma through a respective one of said plurality of first openings.

    摘要: A process for fabricating an ONO floating-gate electrode in a two-bit EEPROM device includes providing a semiconductor substrate and thermally growing a first silicon oxide layer overlying the semiconductor substrate. A thermal anneal is performed after growing the first silicon oxide layer in an ambient atmosphere of at least one of nitric oxide, nitrous oxide and ammonia. In this regard, nitrogen is incorporated into the first silicon oxide layer which leads to a better performance and a higher quality of the ONO structure. A silicon nitride layer is formed to overlie the first silicon oxide layer; and a second layer of silicon oxide is formed to overlie the silicon nitride layer to complete the ONO structure.

    摘要: Photolithographic processing is enhanced by employing a composite comprising two bottom anti-reflective coatings, wherein the extinction coefficient (k) of the upper anti-reflective coating is less than that of the underlying anti-reflective coating. The use of a composite bottom anti-reflective coating comprising partially transparent upper anti-reflective coating substantially reduces reflective notching in the photoresist layer, particularly when employing i-line or deep UV irradiation to obtain sub 0.35 &mgr;m features.

    摘要: A process for fabricating a MONOS type Flash cell device having a periphery field oxide region and a bit-line region includes providing a semiconductor substrate and growing a barrier silicon oxide layer to overlie semiconductor substrate. Thereafter, a thick silicon nitride layer is formed to overlie the barrier silicon oxide layer. A mask and etch are performed at the periphery of the MONOS type cell to form a trench in the semiconductor substrate. The periphery field oxide region is formed by depositing silicon oxide to fill the trench. Thereafter, a mask and etch are performed at the core of the MONOS cell to form a trench in the semiconductor substrate. The bit-line oxide region is formed by depositing silicon oxide to fill the trench. Thereafter, the thick silicon nitride layer is removed. Since the periphery field oxide region and bit-line region are formed before the thick nitride layer is removed, the formation of an unwanted bird's beak is reduced.

    摘要: A local interconnection to a device region in/on a substrate is formed by depositing either silicon oxynitride or silicon oxime as an etch stop layer, at a temperature of less than about 480.degree. C. to increase the hot carrier injection (HCI) lifetime of the resulting semiconductor device. A dielectric layer is then deposited over the etch stop layer and through-holes are etched exposing the etch stop layer using a first etching process. A second etching process is then conducted, which etches through the etch stop layer exposing at least one device region. The resulting through-hole is then filled with conductive material(s) to form a local interconnection.
