    Abstract: A semiconductor device includes a source via having a body portion and a barrier layer surrounding the body portion, and the body portion is in physical contact with the source contact. Furthermore, the barrier layer includes at least one sidewall section separating the source via from an adjacent via structure. As such, the via to via leakage may be prevented. Overall, by providing a semiconductor device having the above structures, the contact resistance is reduced, and the device performance is further improved.
