Latest Patents

Matsuo's latest patents focus on a manufacturing method of CMOS transistors. In this innovative process, gate electrodes of an N-channel transistor and a P-channel transistor are formed on a semiconductor substrate with a gate insulator in between. After conducting a first thermal treatment to the gate electrodes, N-type heavily doped diffusion layers, which serve as the source or drain of the N-channel transistor, are formed using the gate electrode of the N-channel transistor as a mask. Following this, a second thermal treatment is conducted on the N-type heavily doped diffusion layers at a lower temperature than that of the first thermal treatment. Subsequently, P-type heavily doped diffusion layers, which act as the source or drain of the P-channel transistor, are formed using the gate electrode of the P-channel transistor as a mask. Finally, a third thermal treatment is applied to the P-type heavily doped diffusion layers at a lower temperature than that of the second thermal treatment.
