Hey there chief!! I am looking to obtaining Quartz wafers (ST-cut) for one of my experiments; and the general consensus is that you're the man to talk to about getting them. Basically, what I need is 4" quartz-ST substrates rigid enough for MFL-type processing. I would appreciate any info on: 1) sources 2) time to delivery 3) price $$$ 4) your experience on quality and processing Thanks.... Shuvo
