  • Publication number: 20200098545
    Abstract: An electron beam lithography system and an electron beam lithography process are disclosed herein for improving throughput. An exemplary method for increasing throughput achieved by an electron beam lithography system includes receiving an integrated circuit (IC) design layout that includes a target pattern, wherein the electron beam lithography system implements a first exposure dose to form the target pattern on a workpiece based on the IC design layout. The method further includes inserting a dummy pattern into the IC design layout to increase a pattern density of the IC design layout to greater than or equal to a threshold pattern density, thereby generating a modified IC design layout. The electron beam lithography system implements a second exposure dose that is less than the first exposure dose to form the target pattern on the workpiece based on the modified IC design layout.

  • Publication number: 20190148110
    Abstract: In a method of manufacturing a photo mask for lithography, circuit pattern data are acquired. A pattern density, which is a total pattern area per predetermined area, is calculated from the circuit pattern data. Dummy pattern data for areas having pattern density less than a threshold density are generated. Mask drawing data is generated from the circuit pattern data and the dummy pattern data. By using an electron beam from an electron beam lithography apparatus, patterns are drawn according to the mask drawing data on a resist layer formed on a mask blank substrate. The drawn resist layer is developed using a developing solution. Dummy patterns included in the dummy pattern data are not printed as a photo mask pattern when the resist layer is exposed with the electron beam and is developed.

  • Patent number: 9490739
    Abstract: A rotation speed control circuit with function of auto-calibrating rotation speed error is disclosed. The rotation speed control circuit includes a first multiplexer, a second multiplexer, an error amplifier and a current compensation circuit. In calibration mode, the rotation speed control circuit selects a calibration clock signal and a calibration voltage through the first multiplexer and the second multiplexer correspondingly according to a mode switch signal, and adjusts current value of a first current accordingly. In other words, the rotation speed control circuit utilizes the first current to compensate error of the external capacitor through the calibration clock signal fixed and the calibration voltage fixed in the duration of calibration mode, so as to avoid that aging of the external capacitor leads to rotation speed error and then affects the whole operation.
