Active Adjustment of the Subreflector Shape for the Large Dual-Reflector Antenna

open access: yesMicromachines, 2023
A shape adjustment method for subreflectors based on minimizing the residual wavefront error of the large dual-reflector antenna is presented. This method is used to compensate for the antenna structural deformation caused by environment loading.

A Simulation Study for Typical Design Rule Patterns in 5 nm Logic Process with EUV Photolithographic Process

open access: yesJournal of Microelectronic Manufacturing, 2019
5 nm logic technology node is believed to be the first node that will adopt Extremely Ultra-Violet (EUV) lithography on a large scale. We have done a simulation study for typical 5 nm logic design rule patterns.
