Jordan Valley to Introduce a Fast Wide Angle Micro-XRD Metrology Tool
April 06, 2006
Austin, TX, April 6, 2006
Jordan Valley has taken a key position in the "Metrology Using X-Ray Technology" (MUXT) consortium where they will introduce a new, fast Wide Angle Micro-XRD tool for monitoring Cu/low k processes. Also participating in the consortium is ST Microelectronics, Philips Semiconductors and CEA- LETI.
The MUXT project is part of the "Semiconductor Equipment Assessment for NanoElectronic Technologies" (SEA-NET) program. This is an R&D; venture funded by the European Commission (IST-027982). SEA-NET programs evaluate and assess prototype equipment and novel enhancements to existing equipment and their application to next generation semiconductor technologies.
The main objective of the MUXT consortium is the development, assessment and improvement of a 300mm fully automated x-ray metrology platform.
The specific objective for Phase I is to evaluate second generation X-Ray Reflectivity (XRR) and Small Angle X-Ray Scattering (SAXS) technology for 65 nm and 45 nm challenges. SAXS is a technique for measuring pore size and distribution, capable of pore size determination with pore diameters below ten angstroms. It's the only non-destructive technique for providing information about pore size and distribution in the marketplace. The project will concentrate on SAXS performance improvements on high scatter samples and XRR improvements on ultra thin films (below 30 angstroms).
Phase II will evaluate fast Wide Angle Micro-XRD (WAXRD) as a stand-alone metrology tool or as integrated channel with Jordan Valley's XRR and SAXS channels, making it an integrated total solution tool for Cu process ramp up and control. The fast WAXRD channel will be used to monitor the phase growth of Ta, TaN and Cu grains to confirm that deposition processes meet the requirements of 65nm technology nodes and beyond. For the XRD part of the project, the MUXT team will be looking for accurate information about the crystallographic properties of crystalline layers including allotropic form, texture and grain size. The requirements of the project will include developing fast measurement, micro-spot, and automated data processing.
The consortium was first introduced at SEMATECH in Austin in December of last year. The project evaluation site will be Crolles2/ST Microelectronics (NYSE: STM) in Crolles, France.
"Our first partnership with the SEA, to bring our XRR/XRF technology to market, was extremely valuable," commented Sean Jameson, Jordan Valley vice president. "They really helped to validate our current technologies on a broad range of applications. Similarly, we look to the MUXT project to qualify our recent developments in SAXS and our future developments in Low-Res XRD. Jordan Valley remains committed to being the leader in bringing X-ray technologies into high volume manufacturing for 90nm nodes and beyond."
Background Information:
Jordan Valley previously participated in a SEA project, entitled COMBIMEXX, for the evaluation of a combined X-Ray analysis tool. X-Ray Reflectivity (XRR) is a relevant metrology technique to precisely determine the thickness of both transparent and metallic thin films. XRR is also very sensitive to surface and interface roughness and provides information about the film density. X-Ray Fluorescence (XRF) is currently used as a metrology technique to control the thickness and the elemental composition of films. Performance of a new in-line metrology tool, which gathers XRR and XRF to monitor films thickness, was assessed in this project.
