摘要: A method for forming patterns includes the following steps. A first layout including a first target pattern and a first unprintable dummy pattern is provided. A second layout including a second target pattern and a second printable dummy pattern are provided, wherein at least part of the second printable dummy pattern overlaps the first unprintable dummy pattern exposure limit, such that the second printable dummy pattern cannot be formed in a wafer.

摘要: A photomask including first opaque patterns and second opaque patterns is provided. The first opaque patterns are distributed in a first plane defined in the photomask, while the second opaque patterns are disposed above the first opaque patterns and spaced apart from the first opaque patterns. In other words, the first opaque pattern and second opaque pattern are not distributed in the same plane.
摘要翻译: 提供包括第一不透明图案和第二不透明图案的光掩模。 第一不透明图案分布在光掩模中限定的第一平面中,而第二不透明图案设置在第一不透明图案之上并与第一不透明图案隔开。 换句话说,第一不透明图案和第二不透明图案不分布在同一平面中。

摘要: A method for forming a photo-mask is provided. A first photo-mask pattern relating to a first line, an original second photo-mask pattern relating to a first via plug, and a third photo-mask pattern relating to a second line are provided. A first optical proximity correction (OPC) process is performed. A second OPC process is performed, comprising enlarging a width of the second photo-mask pattern along the first direction to form a revised second photo-resist pattern. A contour simulation process is performed to make sure the revised second photo-mask pattern is larger or equal to the original second-mask pattern. The first photo-mask pattern, the revised second photo-mask pattern, and the third photo-mask pattern are output. The present invention further provides an OPC method.

摘要: A calculation method for generating a layout pattern in a photomask includes at least the following steps. A two-dimensional design layout including several geometric patterns distributed in a plane is provided to a computer system. The computer system is used to mark portions of the geometric patterns and generate at least one marked geometric pattern and at least one non-marked geometric pattern. The marked geometric pattern is then simulated and corrected by the computer system so as to generate a 3-D design layout. Through the simulation and correction, the marked geometric pattern and the non-marked geometric pattern are arranged alternately along an axis orthogonal to the plane. The 3-D design layout is outputted to a mask-making system afterwards.
