    摘要: Methods of patterning features of semiconductor devices and methods of processing and fabricating semiconductor devices are disclosed. In one embodiment, a method of processing a semiconductor device includes forming first sidewall spacers on a first hard mask, removing the first hard mask, and forming a first material layer over the first sidewall spacers. A second hard mask is formed over the first material layer and the first sidewall spacers. Second sidewall spacers are formed on the second hard mask, and the second hard mask is removed. At least the first sidewall spacers are patterned using the second sidewall spacers as a mask.

    摘要: Mask sets, layout design, and methods for forming contacts in devices are described. In one embodiment, a method of manufacturing a semiconductor device includes a exposing a first photo resist layer using a first light beam thereby forming first features. The first exposure is performed by the first light beam passing through a first dipole illuminator and then a first mask. A dipole axis of the first dipole illuminator is oriented in a first direction. After exposing the first photo resist layer, forming second features using a second exposure with a second light beam. The second exposure is performed by the second light beam passing through a second dipole illuminator and then a second mask. A dipole axis of the second dipole illuminator is oriented in a second direction. The first direction and the second direction are not perpendicular. The first and the second features comprise a pattern for forming contact holes.

    摘要: Embodiments of the present invention provide a method for making mask shape adjustment The method includes creating a first mask shape; identifying one or more mask segments of the first mask shape as candidate mask segments of needing segment adjustment; applying an optical proximity correction (OPC) process to the first mask shape, the OPC process identifying at least one of the candidate mask segments as a constrained mask segment; applying a rotational adjustment to the constrained mask segment; and creating a second mask shape having the constrained mask segment being rotationally adjusted. A system and a machine-readable medium for performing the above method are also provided.
