摘要： A patterning method is provided. First, a material layer is formed over a substrate. Thereafter, a plurality of directed self-assembly (DSA) patterns are formed on the material layer. Afterwards, a patterned photoresist layer is formed by using a single lithography process. The patterned photoresist layer covers a first portion of the DSA patterns and exposes a second portion of the DSA patterns. Further, the material layer is patterned by an etching process, using the patterned photoresist layer and the second portion of the DSA patterns as a mask.

摘要： A method of forming gates includes the following steps. Dummy gates are formed on a substrate. A spacer material is deposited to conformally cover the dummy gates. A removing process is performed to remove parts of the spacer material and the dummy gates, thereby forming spacers and recesses in the spacers.

摘要： An overlay mark including at least one first overlay mark and at least one second overlay mark is provided. The first overlay mark includes a plurality of first bars and a plurality of first spaces arranged alternately, and the first spaces are not constant. The second overlay mark includes a plurality of second bars and a plurality of second spaces arranged alternately, and the second spaces are constant. Besides, the second overlay mark partially overlaps with the first overlay mark.

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 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.
