    摘要: In patterning a transistor, some of a layer of gate dielectric material is allowed to remain over a semiconductor substrate upon which the transistor is formed. This remaining dielectric material retards the implantation of dopants into the underlying substrate, effectively lengthening a channel region of the transistor. This mitigates unwanted short channel effects, such as leakage currents, for example, and thus mitigates yield loss by establishing a transistor that performs in a more predictable or otherwise desirable manner.
