2005.7.12-14 Participated in SEMICON West 2005

Raytex participated in SEMICON West 2005, held in San Francisco in July.
Booths representing both front-end and back-end processes were combined at Moscone Center starting from this year.
This is the world’s largest trade show, hosting more than 3,500 participant companies.
Various events and seminars are held
concurrently with SEMICON West, and Raytex used the opportunity to collect information on industry trends and the latest technologies.
Raytex had the honor of hosting visiting customers, and was visited in particular by numerous major wafer manufacturers and U.S. device manufacturers. The majority of these visitors were pre-prepared with specific and detailed requests for us to explain and discuss our products.
2004.12.1-3 Raytex Exhibits at Semicon Japan 2004

Raytex took the opportunity to present its products as an exhibitor at Semicon Japan 2004, held on Dec. 1 through Dec. 3, 2004 at the Makuhari Messe Exhibit Hall. Semicon Japan is the largest exhibition held in Japan for the semiconductor manufacturing industry. Exhibitors from 26 countries, representing 1,610 companies, took part in the exhibition, which welcomed over 100,000 visitors in 2004. The Raytex product exhibit included 3 actual systems, including the EdgeScan PLUS wafer edge inspection system for device manufacturing applications, to introduce its newest technology as a new industry presence.
2004. 10.1 Sales Launch of EdgeScan PLUS
Already in the business of sales of inspection systems to help wafer manufacturers in resolving defect problems with the EdgeScan product as its main product offering, on October 1, 2001 Raytex initiated sales of its EdgeScan PLUS product, aimed at the Device Manufacturing market. To that point no inspection systems available on the market was targeted specifically to assist in the fight against material residue and film stress at wafer edges. The EdgeScan PLUS is a unique system that performs high-level automatic monitoring, leveraging Raytex’s proprietary high-tech solutions including optimized resolution, to address the ever-changing conditions of the wafer edge as it goes through film layering at each device process stage.
2004.9.27 Rights Acquired to NanoPro NP1
【What is the "NanoPro NP1"?】
The NanoPro NP1 is a double-sided wafer metrology system utilizing a glancing interferometry method. It is entirely unprecedented in the world in its ability to measure wafer flatness and other conditions at high accuracy with contact at the wafer edge only. Fully using the advantages of glancing interferometry, the NanoPro NP1 makes it possible to measure wafers during the wafer pre-manufacturing stages, which was previously impossible. This one system can perform measurements at all stages from pre-stages at the production facility, up to final inspection before product shipment.
Raytex acquired patent and trademark rights to the NanoPro NP1 product, previously manufactured by a KLA-Tencor Corporation, an equipment manufacturer of proven track record in the wafer measurement and inspection field, and has begun sales of this system worldwide. Previously, Raytex offered its in-house designed DynaSearch XP product for applications in wafer flatness and nanotopography single-sided measurement. Now with the industry shift toward double-sided polishing, Raytex offers its NanoPro NP1 product, designed for double-sided simultaneous measurement applications, which enables even greater reduction in the development cycle.
