41.4: New Capabilities in Vacuum Thermal Evaporation Sources for Small Molecule OLED Manufacturing

A vacuum thermal evaporation source has been developed where blended or single-component organic materials are metered from a cooled reservoir to a heating element. High material utilization, very high deposition rates, and multicomponent deposition with precise composition control are features of this vaporization-on-demand source.

36.1: Invited Paper: Cost Competitive Vacuum Deposition Technology for Small Molecule OLED Manufacturing

This paper will discuss how the unit manufacturing cost of AMOLED displays can be reduced by as much as 40% through the use of a flash vaporization source first presented at SID 2006. This cost reduction is achieved principally through higher materials utilization and higher productivity.

63.1: Responsive Vacuum Deposition Technology for Cost-Effective OLED Manufacturing

The ability to interrupt and reinitiate vaporization rapidly to precisely controlled rates is an important requirement for reducing the deposition cost component of OLED displays for both in-line and cluster tool configurations. A flash vaporization deposition system using closed-loop control is described that achieves these objectives.
