“As spectroscopic ellipsometry rapidly moved to the top of our list of required metrology for our development, Dr. Sun and his team at Ångstrom Sun Technologies provided our technical staff with strong technical support in the time leading up to our instrument purchase. When we decided to move ahead with acquisition of an Ångstrom Sun tool, Richard and his team met a very aggressive manufacturing and shipment schedule, which provided a tremendous benefit to us. And as we develop our own expertise in running the instrument, the Ångstrom Sun team continues to provide rapid, high-quality support for us. We’ve been very happy with our relationship with Ångstrom Sun and look forward to continuing to work with them.” David Maloney, COO, Equity Solar, Inc.
Angstrom Sun Technologies Inc. is a privately held company, headquartered in Boston, USA. The focus of company is to provide a series of cost-effective optical solutions for characterizing thin film thickness, thick coating thickness, their optical properties (refractive index N and extinction coefficient K), surface and interface behavior, alloy concentrations and their uniformities across surface.
Affordable, low cost, but advanced and high performance tools, including spectroscopic reflectometer, microspectrophotometer, microreflectometer, film thickness mapping system, simple desktop film thickness station, and automatic variable angle spectroscopic ellipsometers, offer a way to probe film stacks nondestructively and precisely. In addition, Angstrom Sun Technologies Inc. also delivers advanced analytical services for characterizing thin films, thick coatings and complicated layer stacks.
Angstrom Sun Technologies Inc. designs and manufactures all TFProbe tools in a facility located in Boston, USA. TFProbe tools are sold and distributed by international sales networks.
With performance and professional support as our mission, Angstrom has established a worldwide customer base since 2002, including well-known education institutions, government agencies and Fortune 500 companies, such as NASA Marshall Space Flight Center, National Institute of Standards and Technology, Massachusetts Institute of Technology (MIT), Seoul National University, NanoTech Center (CESTM) at SUNY, Columbia University, Hewlett-Packard Co., Lockheed Martin Co., General Electric (GE), Corning Inc., Bell Laboratories, Johnson-Johnson, Mylan Technologies, Applied Materials (AMAT), Lam Research, Samsung Advanced Institute of Technology(SAIT), and MIT Lincoln Laboratory.
Both spectroscopic ellipsometry and reflectometry are model based technique. Advanced software and professional application support are key to implement ellipsometer and reflectometer tools in various thin film application area. With this in our mind, we always provide unlimited application modeling assistance and free upgrade on our software with our tools. The word "sold" is not our sales activity. Using our tool and getting what you want are our job. A detailed comment from our customers stated so:
“Formally Novellus System and now Lam Research, we are the owners of two SE200BM-M450 450 mm Angstrom Sun Spectroscopic Ellipsometry systems that saw heavy use on the 450mm wafer program at the time. Throughout Dr. Sun and his team supported critical customer requirements for urgent customer demands of a more aggressive edge exclusion by quickly implementing very effective upgrades on the tool; such as, improved software to increase measurement throughput, newly designed ceramic pin posts and an optical camera installation to improve wafer centering, and a motor and cable assembly upgrade which enhanced stage accuracy and repeatability. At the time of purchase the tool was guaranteed for 3mm EE, but these upgrades gave it repeatable 1.5 mm EE capability in order to meet the customer’s stringent demand. Every time we had a newly developed films that required n, k and thickness measurements, Dr. Sun and his team were always available to provide support with modeling development in a timely manner. Angstrom-Sun’s excellent support helped us to meet our customer’s needs for critical 450mm projects. Dr. Sun and his team continue to provide hardware, software and modelling support whenever the need arises. As the tool owner, I appreciate the support and look forward to working with Dr. Sun and his team with a great sense of satisfaction.” Natalie Tran, Metrology engineer, Lam Research Corp.
“The ellipsometer (Model SE200BM-M300, manufactured in 2012 and upgraded to 300mm mapping capability in 2014, by Angstrom Sun Technologies Inc.) is used daily in our department due to the reliability of the measurements, the built in software and the ease at which we can measure a large number of samples due to the 300 mm wafer mapping technology. In addition to all of this, whenever we have difficulty Dr. Sun and his team have provided excellent and prompt technical support which has been extremely helpful in modelling more challenging samples and meeting customer schedules”, Ross Anthony at Applied Materials Inc.
I work in the semiconductor industry and contacted Angstrom Sun Technologies to enquire about their spectroscopic ellipsometer for characterization of our thin films. We were invited for an on-site demo where we were able evaluate the instruments performance and its applicability to our system. While on site Richard went over the various options available to us and helped us in selecting the right tool to meet our characterization requirements. After choosing an instrument (SE200BM-M300) Angstrom Sun was able to quickly deliver and install the tool at our facility within only five weeks. We have been very happy with the performance of the instrument and the high quality of data produced. It has been a pleasure dealing with Richard throughout the entire process. He has provided excellent customer service, promptly replying to emails and answering any questions we have had along the way. In addition, he provided significant help with model development, and incorporated new features in the software to facilitate our analysis.

“I want to thank Dr. Sun and his team at Angstrom Sun Technologies for all of their help with the purchasing of our Spectroscopic Ellipsometer. Dr. Sun and his team took the time to talk with us about our needs and what would best suit them. After we placed the order we experienced an exceptionally quick shipping timeframe (on site two weeks later). Once we received the well packaged ellipsometer, and with the help of one other person we were able to unbox and set up the ellipsometer. Following their well documented instructions, we had the ellipsometer ready to run. Dr. Sun answered our remaining questions and we were able to start taking measurements on our own. After we had worked with the program more, anytime a question would arise, Dr. Sun and his team’s prompt replies kept us working in the right direction into full functionality. Support included helping with the uploading of our own NK table as well as help with the modeling. Thank you Dr. Sun for taking the time to help us better understand Ellipsometry and for putting out an exceptional product”, Benjamin Sheppard at Colorado Concept Coatings
