2. FAQ of GaSb Wafer

Q1: Can we have a better Bow and Warp of GaSb wafer, <5um?

A: BOW and WARP of GaSb substrate should be <8um, 5um is too difficult.

Q2: what is the dislocation density in a regular manner and can we have EPD mapping of GaSb wafer ?

A: EPD of GaSb material is <1000, see below mapping:

Q3：Could you please offer us the following characterization data of GaSb substrate?
(TTV, Bow and Warp, Surface Oxide Thickness, FTIR Transmission, Mobility / Carrier Concentration / Resistivity mapping, EPD cartography, …)

A：Usually, all the data of GaSb should be tested after polished and before shipment, but we can show you some example data, like EPD, oxidized-warp-bow, oxidized-TTV-TIR, oxide layer thickness and so on. To obtain detailed information please contact victorchan@powerwaywafer.com.
