Latest Patents

One of Takada's latest patents is a semiconductor sensor device and method for manufacturing the same. This innovative device utilizes MEMS technology, combining machining and material technology with semiconductor technology to detect and measure various physical quantities. The design addresses the issue of cracks that can form in the cap chip and molding resin, ensuring air-tightness between the semiconductor sensor chip and the cap chip. By employing a wet-etched surface on the circumference side of the cap chip, Takada has effectively eliminated cracks caused by vibrations during cutting. Additionally, insulation is enhanced by coating the cap chip's side surface with an insulating protection film.

Another notable patent is the impact-resistant acceleration sensor. This sensor has achieved a high level of impact resistance, preventing the weight bottom surface of the acceleration sensor element from colliding directly with the inner bottom plate of a protection case made of ceramic, glass, or silicon. This design avoids chipping of the weight's edges and corners, even under excessive acceleration or impact. The acceleration sensor features a weight that acts as a pendulum when acceleration is applied, housed within a protection case that includes a regulation plate to limit excessive downward swinging of the weight. An impact buffer material, either a metal layer or a resin layer, is strategically placed on the weight's bottom surface or the inner bottom plate of the protection case.
