1. A computer-implemented method of fabricating an integrated chip (IC), the method comprising:
- designing a first layout by placing and routing a plurality of standard cells that define the IC;
generating a second layout by modifying the first layout during a mask data preparation process related to the first layout, wherein the second layout is generated by connecting first and second patterns from among first layer patterns corresponding to a first layer of the first layout, such that a single mask is applied to the connected first and second patterns, thereby reducing the number of masks necessary for forming the first layer patterns of the first layer of the IC; and
manufacturing the IC according to the second layout.

Abstract
A method of designing a layout of an integrated chip (IC) includes designing a first layout by place and route a plurality of standard cells that define the IC, and generating a second layout by modifying the first layout during a mask data preparation process related to the first layout, wherein the second layout is generated by connecting first and second patterns from among first layer patterns that correspond to a first layer of the first layout, such that the number of masks necessary for forming the first layer patterns is reduced.

13. A method of designing a layout of a standard cell of an integrated circuit (IC), the method comprising;
-
configuring a first layout by placing and routing a standard cell, the standard cell including first and second patterns from among first layer patterns corresponding to a first layer of the first layout; configuring a second layout by modifying the first layout by connecting the first and second patterns among the first layer patterns so that the number of masks required to form the first layer patterns of the standard cell according to the second layout is reduced relative to the number of masks required to form the first layer patterns of the standard cell according to the first layout; and manufacturing the integrated circuit based on the second layout. - View Dependent Claims (14, 15, 16, 17)
