Latest Patents
One of Kouichi Takekawa's latest patents is a film carrier semiconductor device. This device includes a film carrier tape, an outer lead bonding bump mounting portion, a semiconductor chip, inner lead bonding leads, and outer lead bonding bumps. The film carrier tape is made of a tape-like insulating material and features carrying and positioning sprocket holes along its edges. The outer lead bonding bump mounting portion is located in the central part of the film carrier tape, where the semiconductor chip is mounted. The chip has electrode bumps on its pads, while the inner lead bonding leads are arranged in a specific pattern on the tape and connect to these electrode bumps. Additionally, the outer lead bonding bumps are formed on the mounting portion, linking to the corresponding inner lead bonding leads.
Another significant patent is a method of manufacturing a semiconductor device that utilizes a film carrier tape during its process steps. This method does not include any test pads in the film carrier tape. Consequently, the semiconductor element carried in the film is cut at the leads and separated from the tape without conducting any electrical tests. The separated semiconductor element undergoes electrical testing by being installed on a testing substrate designed to accommodate a large number of terminals.
