Abstract: A method for stabilizing bandgap voltage includes the steps of: providing a first layout pattern designated with a first voltage; reducing a critical dimension of the first layout pattern for generating a second layout pattern corresponding to a second voltage; matching the second voltage with a target voltage; and then outputting the second layout pattern to a mask. Preferably, the first layout pattern and the second layout pattern include polysilicon resistor patterns.
