    Abstract: A method of decomposing pattern layout for generating patterns on photomasks is disclosed. The method includes decomposing features of an integrated circuit layout into discrete patterns based on the relation between these features. The features include first features and second features. The first features are then classified into a first feature pattern and a second feature pattern, and the second features are classified into third, fourth, fifth and sixth feature patterns. The spacings of the second features in the fifth and sixth feature patterns are greater than a minimum exposure limits. Finally, the first feature pattern is outputted to a first photomask, the second feature pattern is outputted to a second photomask, the third and fifth feature patterns are outputted to a third photomask, and the fourth and sixth feature patterns are outputted to a fourth photomask.

    Abstract: A method of correcting assist features includes the following steps. At first, a first layout pattern is received by a computer system, and the first layout pattern is split into a plurality of first regions. Subsequently, a plurality of assist features are added into the first layout pattern to form a second layout pattern, wherein at least one of the assist features neighboring any one of the edges of the first regions is defined as a selected pattern. Then, the second layout pattern is split into a plurality of second regions. Afterwards, a check step is performed on the second region including the selected pattern, and the second layout pattern is corrected to form a corrected second layout pattern.

    Abstract: A method of forming trenches is provided. A first layer, a second layer and a third layer are formed on the substrate. A patterned third layer with a plurality of third trenches is formed. A spacer is formed on sidewalls of the third trenches, following by removing a portion of the patterned third layer between the third trenches. By using the spacer and the patterned third layer as a mask, a patterned second layer with a plurality of second trenches is formed. Next, the patterned third layer and the spacer are completely removed, and a block layer is formed on the patterned second layer, filling into the at least one second trench to separate said second trench into at least two parts. The first layer is patterned by using the patterned second layer and the block layer as a mask to form a patterned first layer with first trenches.

    Abstract: A layout pattern decomposition method includes following steps. A layout pattern is received. The layout pattern includes a plurality of features, and an edge-to-edge space is respectively defined in between two adjacent features. A sum of a width of the edge-to-edge space and a width of the feature on a left side of the edge-to-edge space and a sum of the width of the edge-to-edge space and a width of the feature on a right side of the edge-to-edge space are respectively calculated. The sums and a predetermined value are respectively compared. When any one of the sums is smaller than the predetermined value, the two features on the two sides of the edge-to-edge space are colored by a first color and alternatively a second color. The features including the first color are assigned to a first pattern and the features including the second color to a second pattern.
