Rudolph Software Aids High Definition Displays in Mobile Devices
The company's Genesis Enterprise offline yield analysis and data management will be used to maximise factory efficiency and identify causes of yield loss
Rudolph Technologies, Inc. has sold one of its Genesis Enterprise yield management software programs to a major manufacturer of high definition (HD) displays for hand-held devices.
With consumer demand for higher resolution in smaller displays pushing critical dimensions toward the micrometre scale, display manufacturers are deriving large returns from the application of yield enhancement technologies developed in the semiconductor industry.
"Some HD displays for mobile devices now have more than 600 pixels per inch," says Len Labua, senior applications manager in Rudolph's Data Analysis and Review Business Unit.
He adds, "Many of the processes used in their manufacture are similar to semiconductor processes, and at these sizes they are becoming vulnerable to similar types of defects and process variations. HD manufacturers are able to leverage yield management software developed largely for semiconductor manufacturing to achieve significant improvements in process yields. Not only do they get better performance from processes already in production, they can also ramp new processes to production yields faster."
Labua also points out, "This particular sale was to a company formed by a recent merger, and the purchase decision was based in part on previous experience with Genesis Enterprise software within the merged companies. The selection process involved a competitive evaluation, and it was the speed, reliability and ease of use of the software, combined with an established history of excellent support, that persuaded them to continue with Genesis in their newest facility."
Genesis Enterprise, a solution with parametric yield management tools, allows manufacturers to identify domain-specific issues, such as spatial anomalies, processing sequence problems, commonality of effects, and systematic and random yield loss.
Its data management and connectivity infrastructure assures easy, reliable integration of the Genesis software analysis and reporting platform with existing process tools and information systems, allowing process engineers and fab managers to quickly identify root causes of complex problems.
Rudolph says its Genesis Enterprise software, helps manufacturers to achieve greater profitability on products already in high-volume production and gain competitive advantage by quickly getting new products to market.
