Masakatsu Hamaji has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Method for manufacturing semiconductor device
    Patent number: 7473624
    Abstract: There is provided a method for manufacturing the semiconductor device for obtaining capacitance characteristics of a larger capacitance and delay characteristics with higher efficiency. An embodiment according to the present invention employs the configuration of forming the gate polysilicon layer by conducting the customization by using the customized reticle. For example, gate polysilicon layer having a larger dimension such as gate length and the like is formed by using the dedicated gate reticle, only for an user who requests the countermeasure for the EMI noise. Having such process, a larger-scale capacitance can be provided without increasing the process cost.
