Patent number: 7071529Abstract: A semiconductor device includes semiconductor elements and at least one dummy pattern. Each or at least some of the semiconductor elements has a Damascene gate structure or a replacing gate structure and is located in element-forming regions. In addition, at least a dummy pattern is located in a region different from the element-forming regions.

Patent number: 5756382Abstract: Gate electrodes of an N-channel transistor and a P-channel transistor are formed on a semiconductor substrate with a gate insulator therebetween. After conducting a first thermal treatment to the gate electrodes, N-type heavily doped diffusion layers to be a source or a drain of the N-channel transistor are formed using the gate electrode of the N-channel transistor as a mask. After conducting a second thermal treatment to the N-type heavily doped diffusion layers at a lower temperature than that of the first thermal treatment, P-type heavily doped diffusion layers to be a source or a drain of the P-channel transistor are formed using the gate electrode of the P-channel transistor as a mask. Then, a third thermal treatment is conducted to the P-type heavily doped diffusion layers at a lower temperature than that of the second thermal treatment.Type: GrantFiled: January 23, 1997Date of Patent: May 26, 1998Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Mizuki Segawa, Yoshiaki Kato, Hiroaki Nakaoka, Takashi Nakabayashi, Atsushi Hori, Hiroshi Masuda, Ichiro Matsuo, Akihira Shinohara, Takashi Uehara, Mitsuo Yasuhira

Patent number: 5736421Abstract: Mounted on a single semiconductor substrate are a DRAM, MOS transistor, resistor, and capacitor. The gate electrode of the DRAM and the gate electrode of the MOS transistor are formed by a common layer (i.e., a first-level poly-Si layer). The storage electrode of the DRAM. the resistor, and the lower electrode of the capacitor are formed by a common layer (i.e., a third-level poly-Si layer). The plate electrode of the DRAM and the upper electrode of the capacitor are formed by a common layer (i.e., a fourth-level poly-Si layer).Type: GrantFiled: January 23, 1996Date of Patent: April 7, 1998Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Hiroshi Shimomura, Kiyoyuki Morita, Takashi Nakabayashi, Takashi Uehara, Mitsuo Yasuhira, Mizuki Segawa, Takehiro Hirai
