摘要

A method of manufacturing a FinFET device with a fin pitch of less than 20 nm is presented. According to some embodiments, fins are deposited on the sidewall spacers and the sidewall spacers themselves are deposited on the mandrels. The mandrels can be formed by a lithographic process, while the fins and sidewall spacers can be formed by deposition techniques.
