Latest Patents

Some of Kazuo Okada's most notable recent patents include:

1. **Semiconductor device with backmetal and related methods** - This patent discusses the implementation of semiconductor devices, which may consist of a die featuring both first and second sides. A contact pad is coupled to the first side, while a metal layer is affixed to the second side. Notably, the die's thickness is limited to no more than four times that of the metal layer, enhancing device performance and efficiency.

2. **Integrated passive device and fabrication method using a last through-substrate via** - This invention details a method for creating an integrated passive device (IPD) die. The process begins by grinding the backside of a semiconductor substrate to reduce the thickness of a central region, while a mechanical support ring remains intact on the outer portion. A through-substrate via (TSV) is then formed, providing interconnect access to passive components embedded in insulator material on the front surface. The substrate thickness is reduced to less than three-quarters of its original size, allowing for compact device designs.
