Re: "Copper process and Dresden fab in general are doing very well also. Achieved yields on copper SRAMS are as high as ever observed on aluminum parts!!!!"

I would guess these are SRAMS in .25um (not .18um) if they compare to
Al. Also, SRAMs require only 3 levels of metal while the processor probably requires at least 6. Also, SRAM design probably only tests the groundrules at metal 1. The processor logic design will at all levels. So, it's far from a demonstration of .18um copper BEOL but it is a good start.
