Q: I will use these substrates to grow lasers on them.
So, I would need low EPD. What is the lowest possible EPD you could provide?
A:If you need it for growing lasers, yes, it should be EPD<500.
3"-size (100)-GaAs,
Si-doped and carr. conc. > 0.4e18,
single side polished,
laser-marked,
~625um thick,
EPD<500,
EJ or US flat
