    摘要: A gate stressor for a fin field effect transistor (FinFET) device is provided. The gate stressor includes a floor, a first stressor sidewall, and a second stressor sidewall. The floor is formed on a first portion of a gate layer. The gate layer is disposed above a shallow trench isolation (STI) region. The first stressor sidewall formed on a second portion of the gate layer. The second portion of the gate layer is disposed on sidewalls of a fin. The second stressor sidewall formed on the third portion of the gate layer. The third portion of the gate layer is disposed on sidewalls of a structure spaced apart from the fin. The first stressor side wall and the second stressor sidewall do not exceed a height of the fin.
