THICK FILM RESISTOR AND ITS PRODUCTION PROCESS, THICK FILM RESISTOR PASTE AND ITS PRODUCTION PROCESS |
| 摘要 |
<p><P>PROBLEM TO BE SOLVED: To provide a highly reliable lead-free high resistance thick film resistor exhibiting excellent withstand voltage characteristics. <P>SOLUTION: The thick film resistor containing a glass composition and RuO<SB>2</SB>as a conductive material is produced by calcinating them on a substrate. Lattice constant of contained RuO<SB>2</SB>on the a-axis and b-axis is between 4.4919-4.5000Å. Since lattice constant of RuO<SB>2</SB>on the a-axis and b-axis is set within a predetermined range, withstand voltage characteristics of the thick film resistor are enhanced greatly. When such a thick film resistor is formed, thick film resistor paste containing RuO<SB>2</SB>having a lattice constant on the a-axis and b-axis between 4.4919-4.4994Åis employed. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
