Abstract:
1. A semiconductor device, comprising: a Si substrate; and a resistance element formed on said Si substrate, said resistance element comprising: a plurality of first resistance patterns of suicide provided on said substrate at a first level, said first resistance patterns being arranged in parallel with each other with a mutual separation; and a second resistance pattern of suicide provided adjacent to and between said first resistance patterns at a second level lower than said first level, said second resistance pattern being electrically connected in series to said first resistance patterns to form said resistance element, said second resistance pattern having an edge defined by said first resistance patterns, wherein each of the first resistance patterns and second resistance pattern has a substantially identical length, and each second resistance pattern is disposed between a corresponding pair of first resistance patterns, such that the first and second resistance patterns are configured in a complementary arrangement in an alternating sequence, and said second resistance pattern is formed on a device isolation film covering said substrate, said second resistance pattern including a first polysilicon pattern provided on said insulation film and a salicide region formed on a surface part of said first polysilicon pattern defined by said first resistance pattern.
