RIGAKU - Leading with Innovation

Since its inception in Japan in 1951, Rigaku has been at the forefront of analytical and industrial instrumentation technology. In fact, Rigaku means physical science in Japanese, the core of instrumentation. With hundreds of major innovations to its credit, Rigaku and its subsidiary companies are world leaders in the fields of protein and small molecule X-ray crystallography, general X-ray diffraction, X-ray spectrometry, semiconductor metrology, automation, cryogenics and X-ray optics. Rigaku employs over 1,000 people worldwide in the manufacture and support of its analytical equipment. Whether supplying the tools to create better semiconductor chips, enabling drug discovery, improving production line quality, or exploring the new frontier of nanotechnology, Rigaku products and services lead with innovation. Rigaku was chartered to be the world's leading X-ray analytical instrumentation company.

BEWARE - Special Warning Notice about ExpoGuide and FAIRGuide

With the ongoing solicitations, SEMI would like to continue to alert you with questionable professional practices perpetrated against exhibitors by FairGuide.com (Austria) and Expo Guide (Mexico), Event Fair - The Exhibitors' Guide with their misleading directory services. There may be others that we are not aware of and are hence not named here. 

These companies provide legitimate exhibition guides aimed at exhibitors across the globe offering online listing services. They use a form which resembles and organizer's free catalogue listing service, inviting exhibitors to complete the form for an entry in an on-line directory. Unsuspecting exhibitors who sign and return the form are then contracted into a three-year, non-retractable agreement, which could cost the exhibitor a significant amount of money, with very limited foreseeable benefits. The details are often available on the form itself, but are often too small and insignificant to be noticed. It is always wise to really the small print before signing a contract, and if the information is impossible to read then the contract should not be signed. These publications have no connection with SEMI or any of our events, and it is important that all companies are made aware of this. 

Should you receive any communication from the Expo-Guide and Fairguide.com or related company, please IGNORE THEM COMPLETELY and DO NOT COMMUNICATE WITH THEM IN ANY WAY.
