Controlling the LED manufacturing process and driving higher productivity are challenges being addressed by LED manufacturers today. Rudolph products, in operation at leading LED fabs and packaging facilities, comprise a wide range of solutions including integrated process control, in-line automated inspection systems and application-specific wafer handling.

Advanced macro defect inspection systems
Rudolph’s inspection technologies help high-volume LED makers understand the causes of defects and yield loss in their manufacturing processes, ultimately lowering costs and enhancing the performance and reliability of their products. HB LEDs deliver higher performance, but require tighter control of variability and defectivity in the front-end processes, where the LED itself is formed, to ensure process yield and consistent device performance. Understanding and improving front-end processes is critical to achieving the performance and reliability required, while maintaining manufacturing costs that allow success in a very competitive industry.  Rudolph delivers the Total Solution:  front-end inspection, back-end inspection, classification, analysis and review.

Process control software
A cost effective way to advance HB LED manufacturing, the application of fault detection and classification, run-to-run control, factory automation, and yield analysis methods helps ramp new lines and tools and develop insight into line optimizations.  The resulting yield improvements allows LED manufacturers to gain market share through lower ASP and increase profits through R&D investments, as well as enable new markets.

Software Consulting Services
Having well-integrated solutions provide additional benefits to those offered by a standalone process control solution. The combination of analysis, APC, and FDC in a well-integrated system enables more intelligent analysis, technology such as virtual metrology, and tighter process controls. In addition to offering a full suite of process control and analysis solutions, Rudolph Technologies also offers HB LED and photovoltaic consulting and implementation services.  With over twenty years of experience, our team of consultants allows manufacturers to focus on production instead of vendor management and system integration.
