Title: Kazuhiko Sera: Innovator in Semiconductor Technology
Introduction
Kazuhiko Sera is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of semiconductor technology, holding a total of 4 patents. His innovative work focuses on improving the reliability and performance of semiconductor devices.
Latest Patents
One of Kazuhiko Sera's latest patents is a method of making a lead-on-chip device. This semiconductor device is designed to be sealed with a plastic sealing layer, with its thickness regulated to be below a specified value. Due to the reduced thickness of the device, the upper and lower portions of the plastic sealing layer differ in thickness, which can lead to warping and cracking on the side of the semiconductor chip. To address this issue, Sera's invention includes a semiconductor chip with a plurality of defined grooves. This design increases the thickness of the lower portion of the plastic layer, effectively preventing cracks from occurring on the semiconductor chip.
Another notable patent involves a semiconductor device that also features a semiconductor chip with multiple grooves. This design acts as a resisting member, preventing the semiconductor chip from bending. As a result, the thickness of the lower portion of the plastic layer is increased, further reducing the risk of cracks on the semiconductor chip.
