Publication number: 20230280664Abstract: A reticle carrier described herein is configured to quickly discharge the residual charge on a reticle so as to reduce, minimize, and/or prevent particles in the reticle carrier from being attracted to and/or transferred to the reticle. In particular, the reticle carrier may be configured to provide reduced capacitance between an inner baseplate of the reticle carrier and the reticle. The reduction in capacitance may reduce the resistance-capacitance (RC) time constant for discharging the residual charge on the reticle, which may increase the discharge speed for discharging the residual charge through support pins of the reticle carrier. The increase in discharge speed may reduce the likelihood that an electrostatic force in the reticle carrier may attract particles in the reticle carrier to the reticle.Type: ApplicationFiled: May 12, 2023Publication date: September 7, 2023Inventors: Yen-Hsun CHEN, Yi-Zhen CHEN, Jhan-Hong YEH, Han-Lung CHANG, Tzung-Chi FU, Li-Jui CHEN

Publication number: 20230268378Abstract: A deep trench structure may be formed between electrodes of a capacitive device. The deep trench structure may be formed to a depth, a width, and/or an aspect ratio that increases the volume of the deep trench structure relative to a trench structure formed using a metal etch-stop layer. Thus, the deep trench structure is capable of being filled with a greater amount of dielectric material, which increases the capacitance value of the capacitive device. Moreover, the parasitic capacitance of the capacitive device may be decreased by omitting the metal etch-stop layer. Accordingly, the deep trench structure (and the omission of the metal etch-stop layer) may increase the sensitivity of the capacitive device, may increase the humidity-sensing performance of the capacitive device, and/or may increase the performance of devices and/or integrated circuits in which the capacitive device is included.Type: ApplicationFiled: April 28, 2023Publication date: August 24, 2023Inventors: En-Shuo LIN, Sheng KO, Chi-Fu LIN, Che-Yi LIN, Clark LEE
