Abstract:
A semiconductor process for forming gates with different pitches includes the following steps. A gate layer is formed on a substrate. A first mandrel and a second mandrel are respectively formed on the gate layer. A first spacer material is formed to conformally cover the first mandrel but exposing the second mandrel. A second spacer material is formed to conformally cover the first spacer material and the second mandrel. The first spacer material and the second spacer material are etched to form a first spacer beside the first mandrel and a second spacer beside the second mandrel simultaneously. The first mandrel and the second mandrel are removed. Layouts of the first spacer and the second spacer are transferred to the gate layer, thereby a first gate and a second gate being formed. Moreover, a semiconductor process, which forms the first spacer and the second spacer separately, is also provided.
