Latest Patents

One of his latest patents is a semiconductor chip with electrodes on the side surface. This innovative semiconductor device comprises a semiconductor chip substrate, an integrated circuit formed on a surface of the substrate, and metal electrodes extending from the integrated circuit to at least one of the side surfaces. This design allows for a reduced occupation area on wiring circuit boards and facilitates easy exchange of damaged chips. Additionally, when set vertically, it improves heat radiation efficiency. Another significant patent is a floating point digital to analog converter with bias to establish range. This digital-to-analog converter transforms digital data in floating-point representation into an analog signal. The mantissa part of the digital data is converted into a first analog signal using an R-2R resistor ladder network. This first analog signal is then supplied to another R-2R resistor ladder network to produce second analog signals, which are magnifications of the first signal. One of these second analog signals is selectively outputted based on the exponent part of the digital data.
