Claim 18:
19. The method of claim 17, further comprising:
forming a third transistor having a third channel stack having third channel layers over the substrate and extending along the first lateral direction between third epitaxial source/drain features, wherein the third channel stack has a third number of the third channel layers, the third channel layers have a third channel dimension along the second lateral direction, the third epitaxial source/drain features have a third source/drain dimension along the second lateral direction, and the third epitaxial source/drain features have a third volume; and
wherein the third number is greater than the second number, the third channel dimension is about equal to the second channel dimension, the third source/drain dimension is greater than the second source/drain dimension, and the third volume is greater than the second volume.
