Title: Akihiko Nakano: Innovator in Semiconductor Technology
Introduction
Akihiko Nakano is a prominent inventor based in Nara, Japan. He has made significant contributions to the field of semiconductor technology, holding a total of 8 patents. His innovative work focuses on enhancing the security and functionality of semiconductor devices.
Latest Patents
Among his latest patents, Nakano has developed a semiconductor device and method of manufacturing the same. This invention involves securing a chip with an LSI circuit to a board in a level position. The LSI circuit is designed to operate normally only when the chip remains level. Additionally, the back of the chip is processed to create stress, ensuring that if the chip is detached from the board, it deforms and becomes unlevel, thereby preventing normal operation of the LSI circuit. This design effectively protects the semiconductor device from unauthorized analysis.
Another notable patent by Nakano is a semiconductor device wherein the detection of wiring removal triggers impairment of the normal operation of the internal circuit. This device includes a protective film with a light-blocking film covering the circuit principal part. An attempt to exfoliate this film results in a detectable increase in resistance, leading to malfunction or inoperativeness of the circuit. This innovative approach safeguards the circuit principal part from analysis.
