Diffuson resistors have parasitic junction diodes coupled to well or substrate.
Well resistors have parasitic junction diodes coupled to substrate.
When using the above two types of resistors, make sure the junction diodes are reversed biased, so as not to cause significant leakage current.

Poly resistors don't have parasitic junction diodes.
Metal resistors, neither.
