摘要： A method of reducing parametric variation in an integrated circuit (IC) chip and an IC chip with reduced parametric variation. The method includes: on a first wafer having a first arrangement of chips, each IC chip divided into a second arrangement of regions, measuring a test device parameter of test devices distributed in different regions; and on a second wafer having the first arrangement of IC chips and the second arrangement of regions, adjusting a functional device parameter of identically designed field effect transistors within one or more regions of all IC chips of the second wafer based on a values of the test device parameter measured on test devices in regions of the IC chip of the first wafer by a non-uniform adjustment of physical or metallurgical polysilicon gate widths of the identically designed field effect transistors from region to region within each IC chip.
