Latest Patents

One of Numazaki's latest patents is a semiconductor package with a pocket for sealing material. This invention secures the protection of circuit elements from the external environment. The design features a single in-line package (SIP) that fixingly seals a hybrid integrated circuit component within a casing using epoxy resin. A sleeve, bonded to the surface of a ceramic substrate, is formed with silicon rubber into a pocket shape to cover the respective circuit elements. An opening part is made in the sleeve, allowing silicon gel to be poured in as a sealing material, which is then cured to protect the circuit elements.

Another notable patent is for a semiconductor wafer that includes a relatively wide power supply line and ground line, preventing short-circuiting between these lines. The wafer features multiple integrated circuit formation regions where integrated circuits are formed. A silicon oxide film is created on a silicon substrate, with a ground line conductor formed on top. This conductor extends over scribe lines, and a layer insulation film composed of silicon oxide is deposited above it. The power supply line conductor overlaps the ground line conductor and is also extended over scribe lines, ensuring electrical connections between power supply pads and ground pads.
