Patent number: 6452277Abstract: A silicon oxide film is formed to cover a polysilicon plug. A bowing shaped hole is formed. A barrier metal and a metal film are formed, which are successively subjected to prescribed anisotropic etching. Here, because of the RIE-lag effect, the etch rate of the barrier metal becomes smaller in the portion between the side surface of the hole and the metal film than in the other portions, preventing the exposure of the surface of the polysilicon plug. Thus, a semiconductor device ensuring a good electrical connection of metal interconnections is obtained.Type: GrantFiled: April 18, 2000Date of Patent: September 17, 2002Assignee: Mitsubishi Denki Kabushiki KaishaInventors: Kenji Tabaru, Kazunori Yoshikawa, Takahiro Yokoi, Akemi Teratani

Patent number: 6287752Abstract: A resist pattern is formed on stacked first and second conductive films. After second conductive film is patterned, the patterning of first conductive film follows without removing the remaining resist pattern. Resist pattern is completely removed by etching before the patterning of first conductive film is completed. Thereafter, etching is continued using second conductive film as a mask, and the patterning of first conductive film is completed. Thus, a method of forming a pattern for the semiconductor device in which minute interconnection pattern having a stacked structure is formed without an increase in the number of processing steps can be provided.Type: GrantFiled: July 22, 1999Date of Patent: September 11, 2001Assignee: Mitsubishi Denki Kabushiki KaishaInventor: Kazunori Yoshikawa

Patent number: 6228755Abstract: Described is a semiconductor device having a buried multilayer wiring structure, in which there is ensured good conductivity among a plurality of wiring layers. A lower wiring pattern is formed from conductive material, and an upper wiring pattern is formed from conductive material. Insulating layers are provided between the lower wiring pattern and the upper wiring pattern. A connection section is formed so as to penetrate through the insulating layers to thereby establish continuity between the lower and upper wiring patterns, as well as to have a greater cross-sectional area at the end facing the upper wiring pattern and a smaller cross-sectional area at the end facing the lower wiring pattern.Type: GrantFiled: March 12, 1999Date of Patent: May 8, 2001Assignee: Mitsubishi Denki Kabushiki KaishaInventors: Yoshihiro Kusumi, Satoshi Iida, Kazunori Yoshikawa
