Buyers reveal GaAs substrate preferences
Surveys reveal that uniformity and price are the critical parameters used by GaAs device manufacturers and epitaxial wafer suppliers when choosing a substrate supplier.
Strategy Analytics has released the results of surveys detailing customer ratings for bulk and epitaxial GaAs substrate suppliers, revealing that uniformity and price are the critical parameters used by GaAs device manufacturers and epitaxial wafer suppliers when choosing a substrate supplier The two studies: "SI GaAs bulk substrates 2005: vendor ratings and customer satisfaction", and "SI GaAs epitaxial substrates 2005: vendor ratings and customer satisfaction", summarise customer ratings across a range of technical and commercial parameters

Technical parameters include: surface finish, flatness, wafer uniformity, lot uniformity and lot-to-lot uniformity.
And commercial parameters cover: test data, lead time, achieving delivery promise, technical support, response to complaints and price.
"The Asia-Pacific (excluding Japan) epitaxial wafer suppliers have differentiated themselves on cost".
"Aside from IQE, none of the other epitaxial wafer suppliers could match VPEC and MBE Technology wafer pricing", notes Asif Anwar, GaAs Service Director.
"MBE Technology also had the highest rating overall as a result of strong customer ratings in both the technical and commercial parameters".
"Customers rated the top three suppliers of SI GaAs bulk substrates, Sumitomo Electric Industries, Hitachi Cable and Freiberger Compound Materials, highly for technical parameters, with little difference between the three", observes Stephen Entwistle, VP of the Strategy Analytics Strategic Technologies Practice.
"We did see changes in the rank order for commercial performance and in particular, we have seen considerable improvement in AXT's commercial ratings".
