Abstract
An exemplary semiconductor device includes a source feature and a drain feature disposed over a substrate. The semiconductor device further includes a source via electrically coupled to the source feature, and a drain via electrically coupled to the drain feature. The source via has a first size; the drain via has a second size; and the first size is greater than the second size. The semiconductor device may further include a first metal line electrically coupled to the source via and a second metal line electrically coupled to the drain via. The source via has a first dimension matching a dimension of the first metal line, and the drain via has a second dimension matching a dimension of the second metal line. The first metal line may be wider than the second metal line.
