Latest Patents

Fujimoto holds a patent for a lead frame and method of mounting a semiconductor chip. This invention involves a unit part of a lead frame designed for mounting a semiconductor chip. The design includes connecting leads and supporting leads that extend from the lead frame main body toward the semiconductor chip mounting region. A movable part and a spring part are incorporated to elastically support the movable part. This innovative approach allows the tip portion of the supporting lead to butt against the side face of the semiconductor chip during mounting, ensuring that the chip is securely supported and fixed. Notably, the base portions of the supporting leads, movable part, and spring part do not remain in the package, preventing stress and volume increase within the package. This invention provides a lead frame for forming a LOC package with high reliability, capable of containing a large-area semiconductor chip within a regulated volume. Fujimoto's patent is a testament to his ingenuity and understanding of semiconductor technology.
