    摘要: A method of designing an active layer mask with a dummy pattern by computer aided design (CAD) in shallow trench isolation using chemical mechanical polishing (CMP) to achieve global planarization. In this method, an original mask is provided with an active region including a diffusion area pattern, a polysilicon area pattern and a well area pattern. The diffusion area pattern and the polysilicon area pattern are expanded by an area of dimension a and the well area pattern is extended inward and outward to an area of dimension b. The expanded diffusion, polysilicon and well areas form a first pattern area. The first pattern area is subtracted from the whole region to obtain a second pattern area. A third pattern area is obtained by performing an AND operation on a dummy array pattern and the second pattern area. Expanding the third pattern area to an area of dimension c, a fourth pattern area is obtained. Finally an active layer mask with a dummy pattern is obtained by performing an OR operation on the fourth pattern area and the diffusion area pattern.

    摘要: In accordance with the invention, a double poly process is used to double the memory density of a buried bit line ROM on the same silicon area. In particular the word-line pitch is decreased to increase the cell density in a direction perpendicular to the word lines. The invention uses a self-aligned method for ROM code implantation and a polyplanarization by chemical-mechanical polishing (CMP) to achieve a self aligned double poly word line structure.

    摘要: A new method of forming a silicon-on-insulator device using large tilt-angle implant is described. A first silicon oxide layer is formed on the surface of a semiconductor substrate. A first layer of tungsten is deposited over the silicon oxide layer and patterned. The semiconductor substrate is etched where it is not covered by the patterned tungsten layer to provide a silicon pillar underlying the patterned tungsten layer. A second silicon oxide layer is formed on all exposed surfaces of the silicon pillar and the silicon semiconductor substrate. A second tungsten layer is deposited over all surfaces of the substrate and anisotropically etched to form spacers on the sidewalls of the silicon pillar. An oxygen ion implantation is performed at a tilt angle to form implanted regions within the semiconductor substrate wherein the implanted regions extend and intersect under the silicon pillar. The tungsten layers are removed and the substrate is annealed wherein the implanted regions are transformed into silicon dioxide regions. The silicon oxide layers are removed to complete formation of the silicon-on-insulator device in the manufacture of an integrated circuit.

    摘要: A new method of forming the dielectric layer of an integrated circuit is described. A thick insulating layer is formed over semiconductor device structures in and on a semiconductor substrate. A first metal layer is deposited over the thick insulating layer. The first metal layer is etched using conventional photolithography and etching techniques to form the desired metal pattern on the surface of the thick insulating layer. The intermetal dielectric layer is formed by first covering the patterned first metal layer with a layer of silicon oxide. The silicon oxide layer is covered with a layer of spin-on-glass material which is baked and cured. A second layer of silicon oxide completes the intermetal dielectric layer. Via openings are formed through the intermetal dielectric layer to the underlying patterned first metal layer. A large tilt-angle implant is made into the sidewalls of the via openings to transform the exposed spin-on-glass layer so that it will not absorb moisture from the atmosphere thereby preventing outgassing from the intermetal dielectric layer, and thus preventing poisoned via metallurgy. A second metal layer is deposited overlying the intermetal dielectric layer and within the via openings and fabrication of the integrated circuit is completed.
