Latest Patents

One of Tsukamoto's latest patents involves a method of manufacturing a semiconductor device. In this patent, a control gate electrode and a memory gate electrode of a memory cell of a non-volatile memory are formed in a memory cell region of a semiconductor substrate. A dummy gate electrode is also formed in a peripheral circuit region. N-type semiconductor regions for a source or a drain of the memory cell are created in the memory cell region, along with n-type semiconductor regions for a source or a drain of MISFET in the peripheral circuit region. A metal silicide layer is then formed over the n-type semiconductor regions, but it is not formed over the control gate electrode, the memory gate electrode, and the gate electrode. Subsequently, the gate electrode is removed and replaced with the gate electrode for MISFET. After this replacement, a metal silicide layer is formed over the memory gate electrode and the control gate electrode.
