Publication number: 20230343692Abstract: An electronic package is provided and includes a substrate structure, an electronic element disposed on the substrate structure and an encapsulation layer encapsulating the electronic element, where at least one functional circuit is formed on a surface of a substrate body of the substrate structure, and a wire having a smaller width is arranged on a boundary line at a junction between an encapsulation area and a peripheral area, so that when a mold for forming the encapsulation layer is formed to cover the substrate structure, the mold will create a gap around the wire to serve as an exhaust passage. Therefore, when the encapsulation layer is formed, the exhaust passage can be used to exhaust air, so as to avoid problems such as the occurrence of voids or overflows of the encapsulation layer.Type: ApplicationFiled: July 7, 2022Publication date: October 26, 2023Applicant: SILICONWARE PRECISION INDUSTRIES CO., LTD.Inventors: Wen-Chen Hsieh, Ya-Ting Chi, Chia-Wen Tsao, Hsin-Yin Chang, Yi-Lin Tsai, Hsiu-Fang Chien

Patent number: 8293061Abstract: The present invention relates to a method for bonding two surfaces to one another. The invention particularly pertains to the use of such method in which one of the surfaces is a polymeric plastic (and more preferably a polymeric thermoplastic (especially poly-(methyl methacrylate) (“PMMA”) or cyclic olefin copolymer (“COC”)). More particularly, the invention relates to treating at least one of the contacting surfaces with UV in the presence of oxygen to thereby generate ozone (O3) and atomic oxygen under conditions of temperature below that of the glass transition temperature of the polymeric plastic. The UV/O3-mediated bonding results in high bond strength and zero-deformation method. This bonding method can be applied to micro/nano-scale polymer devices, and particularly to microfluidic devices, for a low cost, high throughput, high yield advantage.Type: GrantFiled: March 6, 2009Date of Patent: October 23, 2012Assignee: University of Maryland College ParkInventors: Donald Lad DeVoe, Chia-Wen Tsao
