    Abstract: A substrate having thereon a first dielectric layer, a second dielectric layer, and a hard mask layer is provided. A partial via is formed in the second dielectric layer and the hard mask layer. A first photoresist pattern with a first trench opening above the partial via and a second trench opening is formed on the hard mask layer. The hard mask layer and the second dielectric layer are etched through the first trench opening and the second trench opening, thereby forming a first dual damascene structure comprising a first trench and a first via, and a second trench in the second dielectric layer, respectively. A second photoresist pattern having a self-aligned via opening above the second trench is formed. The second dielectric layer is etched through the self-aligned via opening, thereby forming a second dual damascene structure comprising the second trench and a second via under the second trench.

    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.
