Title: Machio Segawa: Innovator in Semiconductor Technology
Introduction
Machio Segawa 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 designs and solutions have paved the way for advancements in semiconductor devices.
Latest Patents
One of Segawa's latest patents involves a semiconductor device that features nine surface micro-bumps arranged in a 3×3 matrix on a semiconductor substrate. This device includes a transistor with first and second diffusion layers formed on the substrate, along with power-supply wiring. The first diffusion layer connects to one of the surface micro-bumps, while the second diffusion layer connects to the power-supply wiring. The transistor is strategically placed between the surface micro-bumps located on opposite edges in the X direction.
Another notable patent is for a semiconductor device with aligned bumps. In this design, semiconductor chips with multiple signal through-silicon vias (TSVs) are stacked. Traditionally, a significant amount of man-hours was required to perform continuity tests on each signal TSV. However, Segawa's invention eliminates the need for direct continuity tests on signal TSVs. Instead, dummy bumps are arranged alongside the signal TSVs, allowing for a continuity test of the conduction path that can detect bonding defects on the surfaces of the stacked semiconductor chips.
