Latest Patents

Keovisai holds a patent for "Wafer edge deposition for wafer level packaging." This patent describes semiconductor processing methods and apparatuses that include providing a first wafer to a processing chamber. The first wafer has a thickness, a beveled edge, a first side, and a plurality of devices formed in a device area on the first side. The device area has an outer perimeter, and the process involves depositing an annular ring of material on the first wafer. This annular ring covers a region of the beveled edge and the outer perimeter of the device area, with an inner boundary closer to the center point of the first wafer than the outer perimeter. The process also includes bonding a second substrate to the plurality of devices and to a portion of the annular ring of material, followed by thinning the thickness of the first wafer. Keovisai's innovative approach has the potential to improve the efficiency and effectiveness of semiconductor packaging.
