I know there are places where they grow large high purity silica (aka quartz) crystals for some kind of electronic use. I suspect its metallic silicon that goes into chips - the quartz is probably for piezoelectric devices. What color are these wafers? (i.e. on the non-gold plated side). (Still wondering if I could get a reject wafer somewhere.. better than trying to peel ceramic off an old chip to see whats inside..) -- ------------------------------------------------------------------------------- Iskandar Taib | The only thing worse than Peach ala Internet: NTAIB@SILVER.UCS.INDIANA.EDU | Frog is Frog ala Peach Bitnet: NTAIB@IUBACS !
