Abstract

A method and structure for mitigating strain loss (e.g., in a FinFET channel) includes providing a semiconductor device having a substrate having a substrate fin portion, an active fin region formed over a first part of the substrate fin portion, a pickup region formed over a second part of the substrate fin portion, and an anchor formed over a third part of the substrate fin portion. In some embodiments, the substrate fin portion includes a first material, and the active fin region includes a second material different than the first material. In various examples, the anchor is disposed between and adjacent to each of the active fin region and the pickup region.
