Publication number: 20240312816Abstract: A reticle pod with backside static dissipation has an inner pod defining an accommodation space for a reticle. Multiple flexible guiding components are correspondingly disposed on multiple outer mounting portions of the inner pod in order to guide an inner cover and an inner base of the inner pod to position without relative displacement. Multiple conductive retainers are correspondingly arranged in the accommodation space to push against a backside of the reticle and form a full-time electrical conduction with the back side of the reticle, so as to establish a static dissipation path by the conductive retainers and the inner pod. Meanwhile, with the conductive retainers pushing against the reticle as well as the flexible guiding components providing the inner cover and the inner base with automatic position guiding, the reticle is automatically pushed and positioned to a center position of the inner base.Type: ApplicationFiled: December 29, 2023Publication date: September 19, 2024Inventors: Ming-Chien Chiu, Chia-Ho Chuang, Hsin-Min Hsueh, Yu-Ruei Chen
