Corning and Soitec to Work Together on the Development of Advanced Substrates for OLED Mobile Displays
Corning Incorporated and the Soitec Group announced an agreement to work together on the development of high-performance silicon-on-glass (SiOG) substrates for the flat panel mobile display market. The two companies will focus their efforts on top-performance backplane substrate technology for organic light-emitting diode (OLED) mobile displays.
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, outstanding 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 Dr. Mark A. Newhouse, senior vice president and director, New Business Development, Corning Incorporated. “This co-development 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 Group. “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 silicon-on-glass 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 proven technique is used to fabricate more than 90 percent of SOI production wafers in the semiconductor industry. Soitec's unique expertise and industrial capabilities, along with its continuous product and process improvements, should be key to accelerating SiOG technology for new market applications.
