Claim:
1. A fin field effect transistor (FinFET) device structure, comprising: a substrate; an isolation structure formed on the substrate; a first fin structure extending above the substrate, wherein the first fin structure is along a first direction; a first transistor formed on the first fin structure, wherein the first transistor comprises: an inter-layer dielectric (ILD) structure formed adjacent to the first transistor, wherein the first gate electrode is in direct contact with a sidewall of the ILD structure, wherein the sidewall of the ILD structure has a bottom portion and a top portion in a cross-sectional view, the first gate dielectric layer above the isolation structure is in direct contact with the bottom portion of the sidewall of the ILD structure, wherein an upper portion of the first fin structure protrudes from the isolation structure.
