Semiconductor device with novel interconnection structure between substrate and pcb
The patent application (Publication Number: US20240038645A1) describes a semiconductor device comprising a package substrate with multiple layers, a plurality of posts with solder anchor portions, and solder balls forming conductive interconnects between the package substrate and a printed circuit board (PCB) device. The conductive points on the package substrate are connected to the posts, which are then linked to corresponding contact points on the PCB. The posts are formed using semiconductor package manufacturing processes and can extend through multiple substrate layers, maintaining a continuous cross-section without geometrical transitions exceeding a certain proportion of the width.
Furthermore, the method described in the patent involves forming posts on the package substrate, adding solder anchor portions, and creating solder balls for interconnects. The process includes forming openings in the substrate layers, affixing posts to conductive pads, and applying solder anchor portions. The height of the posts is determined based on the heights of contact points on the PCB, ensuring optimal interconnection without relying solely on substrate warpage. The method also includes wire bonding processes and solder reflow techniques to create the solder balls efficiently. Overall, the patent application outlines a novel approach to semiconductor device manufacturing, emphasizing precise interconnects and efficient processes for optimal performance.
