A method for forming an integrated circuit (IC) including a silicide block poly resistor (SIBLK poly resistor) includes forming a dielectric isolation region in a top semiconductor surface of a substrate. A polysilicon layer is formed including patterned resistor polysilicon on the dielectric isolation region and gate polysilicon on the top semiconductor surface. Implanting is performed using a first shared metal-oxide-semiconductor (MOS)/resistor polysilicon implant level for simultaneously implanting the patterned resistor polysilicon and gate polysilicon of a MOS transistor with at least a first dopant. Implanting is then performed using a second shared MOS/resistor polysilicon implant level for simultaneously implanting the patterned resistor polysilicon, gate polysilicon and source and drain regions of the MOS transistor with at least a second dopant. A metal silicide is formed on a first and second portion of a top surface of the patterned resistor polysilicon to form the SIBLK poly resistor.
