Abstract
Batch semiconductor packaging structures with back-deposited shielding layer and manufacturing method are provided. A grid having multiple frames is glued on an adhesive substrate. Multiple semiconductor devices respectively align with corresponding frames and are stuck on the adhesive substrate. Then a metal layer covers the semiconductor devices and the grid. A distance between four peripheries of a bottom of each semiconductor device and the corresponding frame is smaller than a distance between the bottom and the adhesive substrate, so that the a portion of the metal layer extended to the peripheries of the bottom is effectively reduced during forming the metal layer. After the semiconductor devices are picked up, no metal scrap is remined thereon. Therefore, the adhesive substrate does not need to form openings in advance and is reusable. The grid is also reusable so the manufacturing cost of the present invention is decreased.
