    摘要: A semiconductor device includes a substrate and a gate formed on the substrate. A gate spacer is formed next to the gate. The gate spacer has a height greater than the height of the gate. A method of forming a semiconductor device includes providing a substrate with a gate layer. A hard mask layer is formed over the gate layer, and both layers are then etched using a pattern, forming a gate and a hard mask. A spacer layer is then deposited over the substrate, gate, and hard mask. The spacer layer is etched to form a gate spacer next to the gate. The hard mask is then removed.
