    • PURPOSE: A high voltage resistance having a bias well is provided to performance of a resistance by combining a doping well with a segment which is arranged between a first terminal and a second terminal. CONSTITUTION: A first doping well is formed on a substrate(22). A dielectric structure is formed on the first doping well(24). A long resistance is formed on the dielectric structure(26). The long resistance comprises a first terminal and a second terminal. A wiring structure is formed on the long resistance(28). The wiring structure combines the first doping well with a segment. The segment is arranged between the first terminal and the second terminal. [Reference numerals] (22) A first doping well is formed on a substrate; (24) A dielectric structure is partially formed on the first doping well; (26) A long resistance is formed on the first doping well and the long resistance comprises a first terminal and a second terminal; (28) A wiring structure is formed on the long resistance and the wiring structure is combined with a segment of the long resistance arranged between the first terminal and the second terminal; (AA) Start; (BB) End
