Publication number: 20240136183Abstract: A photo resist layer is used to protect a dielectric layer and conductive elements embedded in the dielectric layer when patterning an etch stop layer underlying the dielectric layer. The photo resist layer may further be used to etch another dielectric layer underlying the etch stop layer, where etching the next dielectric layer exposes a contact, such as a gate contact. The bottom layer can be used to protect the conductive elements embedded in the dielectric layer from a wet etchant used to etch the etch stop layer.Type: ApplicationFiled: January 2, 2024Publication date: April 25, 2024Inventors: Yu-Shih Wang, Hong-Jie Yang, Chia-Ying Lee, Po-Nan Yeh, U-Ting Chiu, Chun-Neng Lin, Ming-Hsi Yeh, Kuo-Bin Huang

Patent number: 8804323Abstract: An electronic device includes a casing defining a first opening and a through hole, a first antenna, a first cover, and a camera module. The first antenna is mounted in the casing and whose position corresponds to the position of the first opening. The first cover is detachably fixed in the first opening and covering the first antenna. The camera module is mounted in the casing and includes a lens module received in the through hole for converging light incident thereon. The first antenna and the camera module are arranged in a first line, the first cover being fixed in the first opening is separated from the camera module by a first predetermined distance in a first direction parallel with the first line.Type: GrantFiled: August 14, 2012Date of Patent: August 12, 2014Assignees: Hong Fu Jin Precision Industry (ShenZhen) Co., Ltd., Hon Hai Precision Industry Co., Ltd.Inventors: Cho-Chuan Yang, Chun-Hsi Lin, Zhang-Xiang Hu, Nien-Chang Wang, Shu-Hao Lu
