Latest Patents

Uchida's latest patents include a tape carrier and a semiconductor device having tab tape. The tape carrier patent describes a design that enhances the degree of freedom of a fine wiring pattern by reducing the diameter of a via pad. This allows for a finer pitch of the wiring pattern and ensures that a metallic ball can be effectively joined to the via pad, even when the diameter of the ball is maximized. The design features a metallic wiring formed on one side of a tape base material through an adhesive layer, along with multiple via holes that expose via pads of the metallic wiring. The internal wall surfaces of the via holes are subjected to coining-pressing, resulting in tapered holes with extended opening diameters.

The semiconductor device patent outlines a device that incorporates a semiconductor element mounted on inner leads of a TAB tape. It includes first and second heat radiator elements that support the TAB tape in a sandwich manner. A sealing resin fills the space between the heat radiator members, hermetically sealing the interior surfaces of the leads of the TAB tape. This innovative design ensures effective thermal management for the semiconductor element.
