摘要:
A method for making a semiconductor device is described. That method comprises forming a dielectric layer on a substrate, and forming a first metal layer on a first part of the dielectric layer, leaving a second part of the dielectric layer exposed. After a second metal layer is formed on both the first metal layer and the second part of the dielectric layer, a masking layer is formed on the second metal layer.
摘要:
A transistor comprising a gate electrode formed on a gate dielectric layer formed on a substrate. A pair of source/drain regions are formed in the substrate on opposite sides of the laterally opposite sidewalls of the gate electrode. The gate electrode has a central portion formed on the gate dielectric layer and over the substrate region between the source and drain regions and a pair sidewall portions which overlap a portion of the source/drain regions wherein the central portion has a first work function and said pair of sidewall portions has a second work function, wherein the second work function is different than the first work function.
