Latest Patents
One of Isono's latest patents is an electrostatic protective device and method for fabricating the same. This invention provides a highly effective means of protecting sensitive devices such as integrated circuits (ICs) and large-scale integrations (LSIs) from electrostatic damage. The method simplifies the structure compared to conventional devices sealed in glass containers, ultimately reducing size and cost. The chip-type electrostatic protective device features an inner insulating layer made of organic resin with multiple holes defining air gaps, outer insulating layers on both sides, and circuit segments that create a discharge gap within the air gaps. The assembly is designed to be cut into individual chip-type devices, allowing for efficient interconnection.
Another significant patent by Isono is a chip fuse and the process for its production. This chip fuse consists of an organic resin-made insulating substrate with electrodes at the terminals. It includes current protecting element wiring portions and a current protecting element positioned between the electrodes. The current protecting element is designed to be thin, measuring between 3-8 micrometers, and is supported by a high tracking resistance organic resin layer. This innovative design ensures that the chip fuse does not ignite or smoke, while also exhibiting excellent clearing characteristics.
