" the smaller the die , the less your percentage of good dies "
huh? Defects appear statistically per wafer area. If die is smaller, then there is less chance of defect. Also manufacturers try to make square dice so more can fit on circular wafer.
arisythilia,
usually when I hear "SiGe", I take it to mean SiGe substrate used for high performance bipolar transistors.
to be perfectly clear, you mean SiGe used to strain silicon..
