    摘要: An oxide-containing layer (18) is formed directly on a semiconductor layer (12) in an NVM region (14), and a first partial layer (20) of a first material is formed over the oxide-containing layer in the NVM region. A first high-K dielectric layer (22) is formed directly on the semiconductor layer in a logic region (16). A first conductive layer (24) is formed over the first dielectric layer in the logic region. A second partial layer (26) of the first material is formed directly on the first partial layer in the NVM region and over the first conductive layer in the logic region. A logic device is formed in the logic region. An NVM cell is formed in the NVM region, wherein the first and second partial layer together are used to form one of a charge storage layer (28) if the cell is a floating gate cell or a select gate (28) if the cell is a split gate cell.

    摘要: A first conductive layer (30) and an underlying charge storage layer (20) are patterned to form a control gate (32) in an NVM region (12). A first dielectric layer (34) and barrier layer (35) are formed over the control gate. A sacrificial layer (36) is formed over the barrier layer and planarized. A first patterned masking layer (38) in the NVM region defines a select gate location laterally adjacent the control gate in the NVM region. A second masking layer (38) defines a logic gate location in the logic region (14). Exposed portions of the sacrificial layer are removed such that a first portion remains at the select gate location and a second portion remains at the logic gate location. A second dielectric layer (52) is formed over, and planarized to expose, the first and second portions. The first and second portions are removed to result in openings at the select gate location and at the logic gate location which expose the barrier layer.

    摘要: Improved dimensional accuracy of the gate electrode structure in the peripheral circuitry region of a semiconductor device is achieved by reducing ARC loss during photoresist stripping associated with plural mask formation in the core memory cell region during patterning and ion implantations. Embodiments include sequentially etching the stacked gate electrode structure in the core memory cell region, photoresist stripping and etching to form the gate electrode structure in the peripheral circuitry region. Subsequently, plural maskings and ion implantations are implemented in the core memory cell region with attendant photoresist strippings.
