Patent ID: 7462538

Claim:
A method of manufacturing a semiconductor device, the method comprising: forming a first transistor, the first transistor including at least two first gate electrodes, a first gate dielectric being disposed proximate each of the at least two first gate electrodes, the first gate dielectric comprising a first gate dielectric material; and forming a second transistor proximate the first transistor, the second transistor including at least two second gate electrodes, a second gate dielectric being disposed proximate each of the at least two second gate electrodes, the second gate dielectric comprising a second gate dielectric material, wherein the second gate dielectric material is different than the first gate dielectric material, wherein forming the first transistor and forming the second transistor comprises forming at least one fin structure, the at least one fin structure comprising channels of the first transistor and the second transistor, further comprising forming a first material over the at least one fin structure, forming a second material over the first material, removing the second material and the first material from over the at least one fin structure of the second transistor, and forming a third material over the at least one fin structure of the second transistor, wherein the first material and the second material comprise the first gate dielectric material of the first transistor, and wherein the third material comprises the second gate dielectric material of the second transistor.
