A team of IBM researchers in Zurich, Switzerland with support from colleagues in Yorktown Heights, New York has developed a relatively simple, robust and versatile process for growing crystals made from compound semiconductor materials that will allow them be integrated onto silicon wafers -- an important step toward making future computer chips that will allow integrated circuits to continue shrinking in size and cost even as they increase in performance.
Appearing this week on the cover of the journal Applied Physics Letters, from AIP Publishing, the work may allow an extension to Moore's Law, the famous observation by Gordon Moore that the number of transistors on an integrated circuit double about every two years. In recent years some in the industry have speculated that our ability to keep pace with Moore's Law may become exhausted eventually unless new technologies come along that will lend it leash.
"The whole semiconductor industry wants to keep Moore’s Law going. We need better performing transistors as we continue down-scaling, and transistors based on silicon won’t give us improvements anymore," said Heinz Schmid, a researcher with IBM Research GmbH at Zurich Research Laboratory in Switzerland and the lead author on the paper.
