  • Patent number: 11257675
    Abstract: A semiconductor device having a substrate, a dielectric layer, a polycrystalline silicon (“poly”) resistor, a drain, and a source is disclosed. After implantation, the poly resistor may have a lateral doping profile with two peaks, one near each edge of the poly resistor, and a trough near the middle of the poly resistor. Such a doping profile can allow the poly resistor to have a resistance that is insensitive to small variations in critical dimension of the poly resistor. The resistance of the poly resistor may be determined by the doping dose of the tilted implant used to form the poly resistor. The tilted implant may be used to form the drain and the source of a transistor substantially simultaneously as forming the poly resistor.
