Patent number: 11461604Abstract: Embodiments of the disclosure provide for improved print position compensation, for example to improve accuracy of print job(s) performed by a printer. The print position compensation enables an offset of the time until printing occurs on a print media to account for changes and/or erroneous movement in a print media, such as due to slippage and/or other results of a force applied to the print media. Particular embodiments determine data values derived both for an output phase and a retraction phase of the printer's operation. Various embodiments generate a print position compensation based on sensor-based edge position distances determined during each of a media output phase and a media retraction phase. Alternatively or additionally various embodiments generate a print position compensation based on sensor-based media movement phase timestamp differentials determined during each of a media output phase and a media retraction phase.Type: GrantFiled: August 20, 2021Date of Patent: October 4, 2022Assignee: Datamax-O'Neil CorporationInventors: Cheng Khoon Ng, Heng Yew Lim, Shufeng Zheng, Jang Wei Chao

Publication number: 20220285155Abstract: Implantation mask formation techniques described herein include increasing an initial aspect ratio of a pattern in an implantation mask by non-lithography techniques, which may include forming a resist hardening layer on the implantation mask. The pattern may be formed by photolithography techniques to the initial aspect ratio that reduces or minimizes the likelihood of pattern collapse during formation of the pattern. Then, the resist hardening layer is formed on the implantation mask to increase the height of the pattern and reduce the width of the pattern, which increases the aspect ratio between the height of the openings or trenches and the width of the openings or trenches of the pattern. In this way, the pattern in the implantation mask may be formed to an ultra-high aspect ratio in a manner that reduces or minimizes the likelihood of pattern collapse during formation of the pattern.Type: ApplicationFiled: June 1, 2021Publication date: September 8, 2022Inventors: Wei-Chao CHIU, Yong-Jin LIOU, Yu-Wen CHEN, Chun-Wei CHANG, Ching-Sen KUO, Feng-Jia SHIU
