    摘要: A method of forming a semiconductor device comprises providing a portion of a semiconductor device structure, wherein the portion includes a region susceptible to hydrogen incorporation due to subsequent device processing. For example, the subsequent device processing can include one or more of (i) forming a layer over the region, wherein the layer includes hydrogen and (ii) using gases containing hydrogen in a plasma for the subsequent device processing, wherein the semiconductor device is subject to an undesirable device characteristic alteration by hydrogen incorporation into the region. The method further comprises forming a hydrogen barrier layer overlying the region, wherein the hydrogen barrier layer prevents substantial migration of hydrogen made available due to the subsequent device processing into the underlying region. The method further includes performing the subsequent device processing.

    摘要: Forming a semiconductor device in an NVM region and in a logic region using a semiconductor substrate includes forming a dielectric layer and forming a first gate material layer over the dielectric layer. In the logic region, a high-k dielectric and a barrier layer are formed. A second gate material layer is formed over the barrier and the first material layer. Patterning results in gate-region fill material over the NVM region and a logic stack comprising a portion of the second gate material layer and a portion of the barrier layer in the logic region. An opening in the gate-region fill material leaves a select gate formed from a portion of the gate-region fill material adjacent to the opening. A control gate is formed in the opening over a charge storage layer. The portion of the second gate material layer is replaced with a metallic logic gate.
