Delving into a very specific segment of the computer chip field, Strategy Analytics (News
) has released a report on the industry for processor components referred to as “GaAs” and “epitaxial” wafers. GaAs stands for “gallium arsenide,” a compound used as a semiconductor in integrated circuits, LEDs, and solar cells. “Epitaxial” refers to a process in which a layer of single-crystal silicon is deposited onto a single-crystal silicon wafer.
The report, ““GaAs Bulk and Epitaxial Wafer Vendor Ratings and Customer Satisfaction 2007,” as its name suggests, looks at how manufacturers in this industry are viewed by customers.
Results in the report show that none of the GaAs epitaxial substrate suppliers were rated highly enough to be able to satisfy both the technical and commercial requirements of end users. Hitachi (News
) Cable was ranked best for technical expertise, and three other companies —VPEC, Kopin and IQE — got high rankings for price, lead time, delivery and responsiveness to complaints.
In the GaAs bulk substrate segment, end users continued to express high levels of satisfaction with both Hitachi Cable and FCM. AXT (News
) ranked alongside Hitachi Cable and FCM with strong customer satisfaction across both technical and commercial parameters. AXT was rated highly for the price, surface finish and flatness of its wafers.
“AXT has steadily increased its customer satisfaction ratings over the past few years,” said Asif Anwar, Director of Strategy Analytics' GaAs service, in a statement. “In 2007, bulk substrate users rated AXT on a par with Hitachi Cable and FCM who have traditionally led the Strategy Analytics customer satisfaction ratings.”
