Patents by Inventor XIANLU CUI

XIANLU CUI has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11894343
    Abstract: A semiconductor device is vertically mounted on a medium such as a printed circuit board (PCB). The semiconductor device comprises a block of semiconductor dies, mounted in a vertical stack without offset. Once formed and encapsulated, side grooves may be formed in the device exposing electrical conductors of each die within the device. The electrical conductors exposed in the grooves mount to electrical contacts on the medium to electrically couple the semiconductor device to the medium.
    Type: Grant

  • Patent number: 11756932
    Abstract: A semiconductor device package includes a mechanical support structure that provides mechanical support to a stack of dies, where the dies are laterally offset from each other. The support structure has a sloped surface that is disposed at a non-perpendicular and non-parallel angle to other surfaces of the mechanical support structure. Electrical contacts are disposed on the sloped surface of the mechanical support structure for electrically interfacing with the stacked dies and on a different surface of the mechanical support structure for electrically interfacing with a substrate.

  • Publication number: 20230173720
    Abstract: A molding compound dispensing system identifies a semiconductor device strip having a substrate with a plurality of segments allocated for die stacks. The system obtains topological data of the identified semiconductor device strip for each of the segments, including data indicative of any semiconductor components in each respective segment. The system determines an amount of molding compound to be applied to each of the segments based on the topological data for each respective segment, and causes a molding compound dispenser to dispense the determined amounts of molding compound at each of the segments.
