Publication number: 20230395520Abstract: A package structure includes an interposer, a die, a conductive terminal and an interconnection structure that is disposed on a first side of the interposer. The die is electrically bonded to the interposer and disposed over the interconnection structure. The conductive terminal is connected to the interposer and the die via a conductive bump.

Publication number: 20230395443Abstract: A semiconductor package, which may correspond to a high-performance computing package, includes an interposer, a substrate, and an integrated circuit device between the interposer and the substrate. The integrated circuit device, which may correspond to an integrated passive device, is attached to the interposer within a cavity of the interposer. Attaching the integrated circuit device within the cavity of the interposer creates a clearance between the integrated circuit device and the substrate. In this way, a likelihood of the integrated circuit device contacting the substrate during a bending and/or a deformation of the semiconductor package is reduced. By reducing the likelihood of such contact, damage to the integrated circuit device and/or the substrate may be avoided to increase a reliability and/or yield of the semiconductor package.Type: ApplicationFiled: June 6, 2022Publication date: December 7, 2023Inventors: Po-Chen LAI, Ming-Chih YEW, Li-Ling LIAO, Yu-Sheng LIN, Shin-Puu JENG

Publication number: 20230386988Abstract: Semiconductor packages and methods of fabricating semiconductor packages include bonding structures on a surface of an interposer having non-uniform height dimensions in different regions of the interposer. A plurality of solder connections may contact the pillars and electrically connect the respective pillars of the interposer to corresponding bonding structures on a package substrate. The variation in the heights of the pillars in different regions of the interposer may compensate for warping of the interposer and improve the reliability of the electrical connections between the interposer and the package substrate.Type: ApplicationFiled: May 31, 2022Publication date: November 30, 2023Inventors: Li-Ling Liao, Ming-Chih Yew, Po-Chen Lai, Chia-Kuei Hsu, Shin-Puu Jeng, Meng-Liang Lin

Publication number: 20230378039Abstract: Some implementations herein describe a semiconductor package. The semiconductor package, which may correspond to a high-performance computing semiconductor package, includes an interposer. The interposer includes tapered interconnect structures formed using a laser plug process. The tapered interconnect structures may include a length that is lesser relative to a length of the column-shaped interconnect structures formed using a through-silicon via process. Such a length reduces a thickness of the interposer and reduces a length of electrical connections through the interposer. In this way, a signal integrity may be increased and parasitics of the semiconductor package including the tapered interconnect structures may be reduced to increase a performance of the semiconductor package. Additionally, the reduced thickness of the interposer may reduce an overall thickness of the semiconductor package to save space consumed by the semiconductor package in a computing system.Type: ApplicationFiled: May 23, 2022Publication date: November 23, 2023Inventors: Hsien-Wei CHEN, Meng-Liang LIN, Li-Ling LIAO, Shin-Puu JENG
