Rudolph Technologies, Inc. (NYSE: RTEC) today announced the immediate availability of its new JetStep® lithography systems for advanced packaging processes on wafer and panel formats. The JetStep systems incorporate an option for a new, proprietary submicron lens design, as well as up to 25% increased productivity over the previous JetStep systems. The JetStep wafer stepper will also feature a 20% smaller footprint to reduce associated cleanroom facility costs. The new systems will be highlighted at the SEMICON® China trade show March 20-22 in the Rudolph Technologies booth 4559 in hall N4.
Advanced packaging technologies, such as system-in-package (SiP) and fan-out packages (FOWLP and FOPLP) are being driven by demand from mobile, automotive and high-power computing applications. The new JetStep systems now feature a submicron lens option that accommodates critical customer roadmap requirements such as ultra-fine SiP interconnects and large-scale 50mm package sizes with significant intrafield variation. This field-proven lens with recipe controlled variable NA (numerical aperture) will allow customers to balance resolution and field size for a broader range of applications. In addition, these advanced packages now require lithography systems specifically designed to create redistribution layers (RDLs), silicon interposers, through silicon vias (TSVs), copper pillars and micro-bumps on non-flat, reconstituted wafers. Achieving this with cost in mind, the new JetStep systems include a higher power lamp and unique illumination optics that increase wafer plane light intensity by 250% over the previous JetStep systems to deliver higher productivity and throughput.
“Our latest JetStep systems provide the greatest combination of high resolution and wide field size to address our customers’ longer-range needs for finer and denser features and more integrated systems-in-packages,” said Rich Rogoff, vice president, and general manager of Rudolph’s Lithography Systems Group. “The 20% footprint reduction, manufacturing-proven warped wafer handling, on-the-fly optical focusing, inter-field magnification compensation, and new edge focus and alignment capabilities result in reduced total time per wafer, and, of course, higher throughput clearly reduces cost.”
Alex Chow, Rudolph Technologies’ vice president for strategic marketing, concluded, “Next-generation packaging processes require tighter overlay and finer pitch interconnects on reconstituted wafers and panels where die have shifted from their desired position. Displacement errors can be measured on the lithography tool, but the measurements are slow, typically taking as much time as the exposure. Moving the measurement to a separate system and feeding corrections to the stepper can double throughput. Rudolph’s exclusive StepFAST™ solution is a feed-forward adaptive shot technology that addresses process variations, die placement errors and dimensionally unstable materials. This new method uses a parallel die placement measurement process and advanced analytics to provide a means to balance throughput against yield, adding an extra dimension of flexibility for optimizing profitability.”
