Latest Patents

One of his latest inventions is a physical sensor that includes a substrate with a silicon layer, an oxide film, and a support layer. This sensor features movable and fixed electrodes, along with a lower electrode. The movable electrode is supported by a beam on the support layer, while the fixed electrode faces it. The lower electrode is positioned on the support layer and also faces the movable electrode. This innovative physical sensor is capable of detecting horizontal physical quantities based on capacitance between the movable and fixed electrodes, as well as vertical physical quantities based on capacitance between the movable and lower electrodes. The beam consists of vertical and horizontal beams, with the thickness of the vertical beam being smaller than that of the horizontal beam.

Another notable invention is a semiconductor pressure sensing apparatus. This device includes a metallic stem with a diaphragm and a semiconductor sensor bonded to the diaphragm. The semiconductor sensor comprises a gauge section and first and second bonding pads. The gauge section is designed to deform according to the diaphragm's deformation. The bonding pads are connected to different positions of the gauge section, allowing the electrical resistance between them to change with the diaphragm's deformation. The gauge section is formed from a semiconductor layer of a silicon-on-insulator substrate, and the semiconductor sensor is directly bonded to the diaphragm by activating the contact surfaces.
