Achieves 2.0 Micrometer Resolution and Supports One-Shot Exposure of 65-Inch Displays
With the growing popularity of thin display technology, the flat screen television market is facing an upward demand for 65-inch and larger displays that support 4K and 8K ultra-high definition video. In its awareness of this trend, Canon U.S.A., Inc., a leader in digital imaging solutions, announces the launch of the new MPAsp-H1003T, a flat panel display (FPD) lithography system. The display manufacturing solution is capable of resolving 2.0 micrometer Line/Space (L/S) features across Generation 8 glass panels1, making one-shot exposure of 65-inch displays possible.
Market needs are expected to shift toward high-quality Ultra HD Premium2 certified products exemplified by organic LED (OLED) televisions. The MPAsp-H1003T contributes to highly-efficient mass production of high-quality, 65-inch panels utilizing Generation 8 glass panels, helping to meet the demand for ultra-high definition displays.
Canon FPD lithography systems employ a Reflection Projection Optical System for one-shot exposure and feature a wide-field exposure that enables manufacturing of large panels. Thanks to a newly developed projection optical system and proprietary Canon processing technology, the wide-field MPAsp-H1003T achieves the same 2.0 micrometer L/S resolution as its predecessor model, the MPAsp-H803T released in June 2013.
The MPAsp-H1003T also increases the Canon FPD lithography system maximum area for one-shot exposure of displays from the previous limit of 58 inches to 65 inches, resulting in a 37% reduction3 in cycle time for 65-inch display exposure versus previous models.
Along with the demand for higher-resolution patterning for high-definition flat panel displays, pattern overlay accuracy has become an increasingly important part of the manufacturing process. Non-linear (distorted) components are considered the primary cause of diminished overlay accuracy. To mitigate this problem, the MPAsp-H1003T uses a combination of a simultaneous multipoint alignment system and magnification compensation technology to achieve a 10% improvement in overlay accuracy compared with previous Canon models.
The MPAsp-H1003T can also employ a dual-inline configuration in which a single coater-developer tool4 supplies two FPD exposure systems. This Multi-Module on Glass (MMG) processing approach exposes two different-sized display panels on a single glass plate to increase process efficiency and productivity. MPAsp-H1003T systems in an MMG configuration utilizing the MPAsp-H803T make possible optimized Generation 8 glass panel mass production without lengthening cycle times.
