Abstract:
A method for measuring kink effect of a first semiconductor device, said method comprising:choosing a second semiconductor device, and a third semiconductor device, said first semiconductor device, said second semiconductor device, and said third semiconductor device having same channel length and different channel width;applying a first voltage on a drain electrode of said first semiconductor device, said second semiconductor device, and said third semiconductor device;measuring a plurality of threshold voltage of said first semiconductor device, said second semiconductor device, and said third semiconductor device;measuring a plurality of source to drain current by applying said plurality of threshold voltages on a plurality of gate electrodes of said first semiconductor device, said second semiconductor device, and said third semiconductor device;generating a slope by dividing a first drain current difference by a first channel width difference, said first drain current difference being formed of a subtraction of a second drain to source current of said second semiconductor device and a third drain to source current of said third semiconductor device, said first channel width difference being formed of a subtraction of said second channel width of said second semiconductor device and said third channel width of said third semiconductor device;subtracting a first drain to source current of said first semiconductor device by a product to acquire a parasitic current, said product being formed of the product of said slope and a first channel width of said third semiconductor.
