    摘要: The present invention provides a method for manufacturing a semiconductor device having multiple gate dielectric thickness layers. The method, in one embodiment, includes forming a first layer of gate dielectric material over a semiconductor substrate in a first active region and a second active region of a semiconductor device, and patterning a masking layer to expose the first layer of gate dielectric material located in the first active region. The method further includes subjecting exposed portions of the first layer of gate dielectric material to a nitrogen containing plasma, thereby forming a second layer of gate dielectric material over the first layer of gate dielectric material located in the first active region, incorporating oxygen into the second layer of gate dielectric material located in the first active region, and removing the, patterned masking layer, thereby resulting in a first greater thickness gate dielectric in the first active region and a second lesser thickness gate dielectric in the second active region.

    摘要: A process for forming a polysilicon line having linewidths below 0.23 &mgr;m. The layer of polysilicon (20) is deposited over a semiconductor body (10). A layer of bottom anti-reflective coating (BARC) (30) is deposited over the polysilicon layer (20). A resist pattern (40) is formed over the BARC layer (30) using conventional lithography (e.g., deep UV lithography). The BARC layer (30) is etched with an etch chemistry of HBr/O2 using the resist pattern (40) until the endpoint is detected. The BARC layer (30) and resist pattern (40) are then overetched using the same etch chemistry having a selectivity of approximately one-to-one between the BARC and resist. The overetch is a timed etch to control the linewidth reduction in the resist/BARC pattern. The minimum dimension of the pattern (50) is reduced to below the practical resolution limit of the lithography tool. Finally, the polysilicon layer (20) is etched using the reduced width pattern (50).
