A method for optimizing the number of kernels N used in a sum of coherent sources for optical proximity correction in an optical microlithography process including setting the number of kernels N to a predetermined minimum value Nmin. Meanwhile, the CAMEL application can also provide IN services to mobile subscribers while they are roaming in other networks. A plurality of substrate bonding pads are positioned on the substrate adjacent the integrated circuit die. An outer end of the second metal has been bent downward twice 90 degrees to form a bottom flat as an extended bottom electrode of the package. A method is also provided minimizing the total number of interconnected switches Z within the switch matrix 10 for a particular application.
