Latest Patents

One of Yamada's latest patents is a "Word line driving circuit and method." This invention includes an address decoding signal generating unit and a word line voltage supply unit. The address decoding signal generating unit features an inverter chain that receives and delays a first address decoding signal, outputting the delayed signal. The word line voltage supply unit incorporates a pull-up driver that supplies the delayed first address signal to a selected word line in response to a second address decoding signal. The inverter chain consists of an NMOS transistor that outputs the delayed first address signal, with its source terminal receiving a set voltage that is higher than ground voltage but lower than high voltage.

Another notable patent is the "Method of manufacturing semiconductor device." This method involves forming a gate electrode on a semiconductor substrate, creating spacers on the side walls of the gate electrode, and doping impurities into the semiconductor substrate on both sides of the spacers to form highly doped impurity regions. The spacers are selectively etched to expose portions of the semiconductor substrate, allowing for the formation of more lightly doped impurity regions between the highly doped impurity regions and the gate electrode.
