Key challenges to broad commercialization of the high-quality, cost-effective displays promised by mobile OLED technology, including backplane electron mobility and uniformity, and lower total system cost, are being addressed by this codevelopment work. In turn, electrical backplane performance should enable display manufacturers to achieve complex circuit integration and simplified processing.

“We are pleased to be working with Soitec, a leader in silicon-on-insulator (SOI) and silicon film transfer technology for the semiconductor industry,” said Mark A. Newhouse, senior vice president and director, new business development, Corning. “This codevelopment work should lead to faster delivery of our SiOG substrates, which can enable the development of high-quality, cost-effective OLED displays,” he added.

“This cooperative effort between Corning and Soitec is a natural extension of both companies’ core competencies. Together we hope to create low-cost, high-performance substrates for the mobile flat panel market,” said André-Jacques Auberton-Hervé, president, the Soitec. “In addition to the focus on mobile display substrates, the codevelopment work can explore alternative applications for engineered substrates using glass and semiconductor thin films, which could significantly enlarge our portfolio of applications.”

Corning’s SiOG technology, currently in development, is a thin, single-crystal silicon film applied to Corning display glass. This development is expected to produce an engineered substrate with outstanding electrical mobility and material uniformity, upon which electronic circuits can be easily applied by display manufacturers. The first applications for this technology are anticipated to be small- to medium-sized mobile display devices.

Soitec’s proprietary Smart Cut technology is used to transfer ultra-thin single crystal layers of wafer substrate material (such as silicon) onto another surface. This technique is used to fabricate more than 90% of SOI production wafers in the semiconductor industry.

Soitec is a France-based supplier of silicon on insulator wafers and other engineered substrates.
