发明名称 Accumulation type FinFET, circuits and fabrication method thereof
摘要 This description relates to a fin field-effect-transistor (FinFET) including a substrate and a fin structure on the substrate. The fin structure includes a channel between a source and a drain, wherein the source, the drain, and the channel have a first type dopant, and the channel comprises at least one of a Ge, SiGe, or III-V semiconductor. The FinFET further includes a gate dielectric layer over the channel and a gate over the gate dielectric layer. The FinFET further includes a nitride spacer on the substrate adjacent the gate and an oxide layer between the nitride spacer and the gate and between the nitride spacer and the substrate.
