IPC: H01L29/78
Filed: 2002-02-26
Abstract: <P>PROBLEM TO BE SOLVED: To solve a problem that a breakdown voltage BVdss between a source and a drain is limited since an electric field is easy to concentrate on a B part of the end of an n+ drain layer 39 if the breakdown voltage is further enhanced, though the electric field is hard to concentrate on an A part right under the end of a gate electrode 42 owing to an n- offset drain layer 38, in a conventional transverse power MOS-FET 30.  <P>SOLUTION: Since this transverse power MOS-FET comprises an n-deep drain layer, the electric field does not concentrate not only on the A part right under the end of a gate electrode 23 but on the B part of the end of an n+ drain layer 20. Consequently, electric field breakdown caused at the B part of the end of the n+ drain layer 20 in a conventional manner is hard to be caused, and the breakdown voltage BVdss between the source and the drain is enhanced than heretofore.  <P>COPYRIGHT: (C)2003,JPO

Abstract: <P>PROBLEM TO BE SOLVED: To solve the problem that a Ta<SB>2</SB>O<SB>5</SB>dielectric film is preferably formed on a Cu electrode when an effective MIM structure capacitor is formed by applying LSI for mix installment, but since Cu has a large diffusion coefficient and low heat resistance or oxidation resistance, electric characteristics of the capacitor deteriorate.  <P>SOLUTION: Since diffusion and oxidation of Cu can be controlled by inserting an anti-reaction layer of Ta between a Cu-interconnect and a Ta<SB>2</SB>O<SB>5</SB>dielectric film, leak current density of the capacitor can be reduced. Since deficiency of oxygen in the Ta<SB>2</SB>O<SB>5</SB>dielectric film can be repaired while controlling oxidation of an underlying layer by performing post-heat-treatment of the Ta<SB>2</SB>O<SB>5</SB>dielectric film in an inert atmosphere, variation in the capacitance of the capacitor due to hysteresis and voltage can be reduced. Since an MIM structure capacitor employing a Ta<SB>2</SB>O<SB>5</SB>film having a high permittivity can be formed on the Cu-interconnect, a high integration, low cost LSI for mix installment can be realized.  <P>COPYRIGHT: (C)2003,JPO
