Abstract:
A method of forming a pattern is disclosed. At first, a layout pattern is provided to a computer system. The layout pattern includes at least a first strip pattern and at least a second strip pattern, and a width of the second strip pattern is substantially larger than a width of the first strip pattern. Subsequently, the second strip pattern neighboring the first strip pattern is defined as a selected pattern. Then, an assist pattern is formed in the selected pattern, and the assist pattern does not overlap a center line of the selected pattern. The layout pattern and the assist pattern are further outputted through the computer system onto a mask.
Abstract:
A method for manufacturing a semiconductor device includes providing a substrate having a mask layer formed thereon, providing a first photomask having a first layout pattern and a second photomask having a second layout pattern, the first layout pattern including a plurality of active area portions and at least a neck portion connecting two adjacent active area portions, transferring the first layout pattern from the first photomask to the mask layer to form a plurality of active area patterns and at least a neck pattern connecting two adjacent active area patterns in the mask layer, and transferring the second layout pattern from the second photomask to the mask layer to remove the neck pattern to form a patterned mask. The patterned mask includes the active area patterns. A slot is at least formed between the two adjacent active area patterns.
