Latest Patents

One of Naoki Ishii's latest patents is a method of mounting a semiconductor wafer with a support board on a supporting adhesive tape joined to a ring frame. This method involves cutting a resin sealing sheet into an adhesive sheet piece that is smaller than the wafer. The adhesive sheet piece is then joined to a supporting adhesive tape along with a ring frame. The adhesive tape is sandwiched between upper and lower housings to create a chamber. Within this chamber, a wafer with a support board is placed on a holding table, closely facing the adhesive sheet piece. The chamber is divided into two spaces, and the differential pressure generated within these spaces causes the adhesive tape and adhesive sheet piece to bend toward the wafer, effectively joining the adhesive sheet piece to the wafer.

Another notable patent is an adhesive tape joining apparatus. This apparatus features a collection bobbin positioned on a vertical line that aligns with the center of a supply bobbin. It includes a pair of connection mechanisms located at the front on both sides of a tape housing chamber. An adhesive tape transport carriage, equipped with connection portions at the forward end of its frame, connects to these mechanisms within the apparatus body. This design allows for the loading of a master roll of adhesive tape to the supply bobbin and the unloading of a residual cut tape at the same position.
