Patent ID: 8394696

Claim:
A method of forming a semiconductor device, the method comprising: determining a total capacitance value for a circuit element of the semiconductor device; selecting a first capacitance value for a first capacitor element and a second capacitance value for a second capacitance element, wherein a parallel combination of the first capacitor element and the second capacitor element will obtain the total capacitance value; selecting a first process to form the first capacitor element and a second process to form the second capacitor element such that a process tolerance of the total capacitance value is lessened relative to both the first process alone and the second process alone; forming the first capacitor element using the first process; and forming the second capacitor element in parallel with the first capacitor element using the second process, the second process exhibiting uncorrelated process fluctuations with respect to the first process, wherein the first capacitor element and the second capacitor elements are fixed capacitor elements.
