Method of forming serpentine resistor

A method of forming a serpentine resistor includes: setting a total length of a schematic resistor to make the schematic resistor to have a first resistance according to a sheet resistance; forming, by using a processor, a serpentine layer corresponding to the schematic resistor, forming, by using t...

Zusammenfassung:A method of forming a serpentine resistor includes: setting a total length of a schematic resistor to make the schematic resistor to have a first resistance according to a sheet resistance; forming, by using a processor, a serpentine layer corresponding to the schematic resistor, forming, by using the processor, a dummy layer over a portion of the serpentine layer to form a modified serpentine layer, measuring, by using the processor, a modified length of the modified serpentine layer, and comparing, by using the processor, the total length and the modified length to generate a comparison result.
