Latest Patents

One of Noriaki Shiba's latest patents is for a semiconductor device having a columnar electrode and a method of manufacturing the same. This invention includes a semiconductor chip sealed with an encapsulating resin, where columnar electrodes are connected to electrode pads of the semiconductor chip and extend through the encapsulating resin. The columnar electrodes are made from bonding wires and feature enlarged outer ends. Solder balls are arranged on the surface of the encapsulating resin and are connected to the outer ends of the columnar electrodes. In another example, pin wires are formed by half-cutting bonding wires, bonding one end of each of the bonding wires, and cutting the bonding wires at the half-cut portions.

Another notable patent is for a surface mount type semiconductor device and a method of producing the same, which includes an interposing layer that electrically connects the semiconductor chip with protrusion electrodes. This device consists of a semiconductor chip, balls functioning as external connecting terminals, a substrate that electrically connects the semiconductor chip and the balls, and a mold resin that seals at least a part of the semiconductor chip. The semiconductor device is designed to be mounted onto a printed circuit board via the balls, with the thermal expansion coefficient of the mold resin matched to that of the printed circuit board. A side surface holding portion is formed in the mold resin to restrict thermal deformation of the semiconductor chip.
