  • Publication number: 20160062227
    Abstract: A method of monitoring mask uniformity includes selecting a unit monitor mark pattern and monitor mark locations based on a main cell size, determining a unit monitor mark sampling location and measurement methodology, and starting a mask making process. The mask critical dimension uniformity (CDU) is measured and data is analyzed. A process impact factor is identified if the mask CDU is not within a predetermined specification, and a mask making process parameter is adjusted based on the identified process impact factor. The mask making process, measuring, identifying and adjusting steps are repeated until the mask CDU is within the predetermined specification.
