摘要: A nonvolatile SRAM cell (20) includes a six-transistor SRAM cell portion (22) and a three-transistor nonvolatile memory portion (30). The nonvolatile memory portion (30) is connected to one storage node (101) of the SRAM cell portion (22). The nonvolatile SRAM cell (20) is three-dimensionally integrated in four layers of polysilicon. The nonvolatile memory portion (30) includes a thin film memory cell (32) having an oxide-nitride-oxide structure (41), and is programmable with a relatively low programming voltage. The three-dimensional integration of the nonvolatile SRAM cell (20) and relatively low programming voltage results in lower power consumption and smaller cell size.

摘要: The surface area of a polysilicon electrode is increased by sputtering non-coalescing islands (20) of aluminum onto a silicon dioxide layer (18), which is overlying the polysilicon electrode. The sputtering process allows uniform island formation to be achieved independent of the deposition surface. The non-coalescing islands are then used as a mask, and a portion of the buffer layer (22) and a portion of the polysilicon electrode (26) are etched to form pillar-like regions (30) within the polysilicon electrode.

摘要: EPROM cells include T-shaped floating gates (61, 171) and control gates that surround virtually all of the floating gates (61, 171) except for the portion of the floating gates (61, 171) that lie on a gate dielectric layer (51, 151). The EPROM cells may include customized well regions (22, 122) to allow flash erasing or individual cell erasing for electrically erasable EPROMs. Many different configurations of the memory cells are possible. The configurations of the source regions, drain regions, and well regions (22, 122) may be determined by how a user of the memory cells wants to program or erase the memory cells.

摘要: An anti-reflective coating for use in the fabrication of a semiconductor device includes a thin oxide layer and an overlying layer of silicon oxynitride. The anti-reflective layer is advantageously used in the fabrication of FLASH memory devices which include a layer of polycrystalline silicon and an underlying layer of silicon nitride. After being used to pattern the polycrystalline silicon and silicon nitride, the anti-reflective coating is removed in a solution of hot phosphoric acid with the removal taking place before the silicon oxynitride is exposed to any elevated temperatures.
