The ADPC 302 by Pfeiffer Vacuum is a unique in-process contamination management system for particle contamination monitoring in the semiconductor industry, an innovative product that measures the number of particles in wafer transport carriers (Front Opening Unified Pod, FOUP and Front Opening Shipping Box, FOSB).
The fully automated patented process localizes and counts particles from the carrier surfaces, including the door.
Sub-micrometer particles can cause defects that may lead to considerable yield loss. Even the smallest particles measuring 0.1 µm may damage the structure of semiconductor chips. Qualified by leading fabs, the new ADPC 302 system by Pfeiffer Vacuum can be used for both the serial production, as well as R&D analysis.
The main applications of the system are carrier characterization, cleaning strategy optimization and cleaning quality check.
The dry process (Dry Particle Counter) of the ADPC shows clear benefits compared to the traditional wet method (Liquid Particle Counter), says Pfeiffer Vacuum. The main advantage of the dry process is that the particle measurement is completely automated, integrated in the production process and therefore not requiring time outside of the production period. Further, thanks to its fully automated measurement, the process does not require an additional operator.
Test time is only seven minutes, meaning that the ADPC 302 is up to four times as fast as traditional systems, and it is possible to test eight transport carriers in one hour.
Electronic Fluorocarbons (EFC), headquartered in Massachusetts, utilizes the latest technology for the purification and microanalysis of its legacy fluorinated specialty gases and rare gases for the medical and electronics semiconductor manufacturing industries.
As we head in to 2018, we look back on a very interesting changing market for krypton (Kr), xenon (Xe) and neon (Ne) in 2017. Ne supply this year continued to increase as new plants came on-stream while the demand was growing slowly after the big decline of 2016.
Electronics manufacturing is a highly complex sequence of adding and subtracting material, with the resulting sum yielding circuits sometimes less than one hundred atoms wide. For over 50 years, Moore’s Law has driven an industry to make smaller devices on larger scales.
Sherwood Valve, LLC has launched the company’s new, comprehensive 80+ page compressed gas catalog including industrial gas valves, medical valves, propane cylinder valves, alternative energy valves, specialty valves and pressure relief devices.
Month on month the gasworld website continues to be the primary portal for information, on a global scale, about our industry - be it through the provision of news and features, or information in the expansive company directory section. Launched in 2004, it is the only independent online news provider and information portal for the global industrial gas community and the larger end-user markets. The website also now incorporates news for gasworld US and Specialty Gas Report.
