  • Publication number: 20250053103
    Abstract: Some implementations described herein include operating components in a lithography system at variable speeds to reduce, minimize, and/or prevent particle generation due to rubbing of or collision between contact parts of the components. In some implementations, a component in a path of transfer of a semiconductor substrate in the lithography system is operated at a relatively high movement speed through a first portion of an actuation operation, and is operated at a reduced movement speed (e.g., a movement speed that is less than the high movement speed) through a second portion of the actuation operation in which contact parts of the component are to interact. The reduced movement speed reduces the likelihood of particle generation and/or release from the contact parts when the contact parts interact, while the high movement speed provides a high semiconductor substrate throughput in the lithography system.

  • Patent number: 8983205
    Abstract: Disclosed herein is a method for auto-depicting trends in object contours (referred to as ADTOC). At the heart of ADTOC is a sifting process to determine a significant angular value via evaluating a plurality of angular values in a predefined range. ADTOC is characterized in that a probe-ahead concept is applied to obtain a reference angular value along the current route, and then the probed angular value is used to modify the significant angular value in order to timely correct the subsequent trace direction, thus achieving more accurate trace result. Contours with discontinuous segments caused by noise, obstacles, illumination, shading variations, etc. can also be auto-depicted without requiring a predefined auxiliary route.

  • Patent number: 8542001
    Abstract: In a power circuit for reducing standby power consumption, a power supply is defined to include a primary power system and a stationary power system. The stationary power system outputs a stationary power after obtaining an input power. A control unit controls ON/OFF of the primary power system, obtains the stationary power as the required power, and receives a PS ON/OFF signal for triggering the control unit, so that the control unit controls the primary power system to supply a primary output power. The power supply includes a switch unit having two ends connected to a power circuit for outputting the stationary power and a virtual load respectively. The PS ON/OFF signal is provided for controlling the switch unit. If the switch unit does not receive the PS ON/OFF signal, it is OFF in a standby mode to avoid unnecessary power consumption of the virtual load.
