A recently granted patent (Publication Number: US11848318B2) discloses a package structure designed for electronic components. The structure includes a base with a chip mounted on it, featuring a recess with a surface and sidewall. A control element is positioned between the base and the chip, with an underfill material filling the recess. The chip and control element are electrically connected to the base individually, ensuring efficient functionality and stability.

Furthermore, the patent details a manufacturing method for this package structure. It involves forming trenches on a wafer, attaching control elements to the bottom surface of the trenches, and then sawing the wafer to create individual package units. These units, each comprising a chip and control element, are placed on a base and filled with an underfill material. The method also includes using die attach film and adhesive layers for secure attachment, with specific thickness ranges specified for optimal performance. Additionally, the process involves the use of different materials for the adhesive layer and underfill, ensuring a robust and reliable package structure for electronic devices.
