The obvious factors are types of gas and process gas flow to be abated, as well as the number of process chambers that are feeding the gas scrubber. Beyond that, however, there are a number of facility related factors that are critical to determining the right point of use scrubber for your operation. Many times, these factors can be identified through an hour long phone conversation. In some cases, however, that evaluation requires an on-site consultation. I would be happy to discuss  this further.   I can be reached at 612-328-2312. Todd Erickson, Director of Gas Abatement Division...

Looking at the pros and cons of a new vs. a reconditioned gas scrubber can best be evaluated by breaking the topic down into subject areas: Financial and environmental considerations Perhaps the most compelling reason to buy a reconditioned scrubber is that they’re up to 75% less than an equivalent new gas scrubber. Additionally, purchasing a reconditioned scrubber promotes the re-use/recycling of high quality, well maintained equipment. Equipment Performance and Warranty New scrubbers will obviously function properly, and come with a 1 year warranty. A reconditioned scrubber from CSI goes through an comprehensive cleaning, evaluation and testing procedure before it is CSI Certified. Our...

Lithography represents one of the most important phases in the production of integrated circuits.  Photolithographic steps establish patterns on chips or light-sensitive material called a photoresist. After undergoing a series of chemical treatments, the exposure pattern can be engraved into the photoresist or through a deposition of new material underneath the photoresist. Traditionally, semiconductor manufacturers use an extensive baking (hotplate) process at temperatures of 100-450°C. The low temperature is crucial to avoid degradation of the photoresist properties. However, the hotplate process fabricates one wafer at a time – a time consuming process.  A single silicon wafer may require as many as 50...

GTAW Process and Application For the purpose of this discussion we will focus on the Gas Tungsten Arc Welding (GTAW) process, particularly as it relates to Orbital Welding process capabilities, including TIG (Tungsten Inert Gas) and MIG (Metal Inert Gas) or “Wire Feed” welding.   And, we will keep our discussion around the welding of pipe and tube and the various process systems that utilize tubular materials. These processes are most commonly used to weld thin sections of stainless steel and non-ferrous metals such as aluminum, magnesium, and copper alloys. The processes offer the operator greater control over the weld and allow for...

Yes, in many cases panels can be refurbished, and much more quickly and less expensively than going back to the OEM. The contaminated section must be identified and clearly marked, and then can be sent to an experienced gas system repair company for reconditioning.   It can be done in-house as well, assuming you have a weld shop and follow the right procedures.

The AMI equipment training you provided to us these past 2 days was very informative and educational.  John, you are a very talented teacher - articulate, knowledgeable, and thorough.  You gave us a great understanding of how to perform fusion orbital welding.  I now know how the power supply and cooling systems work, and how the weld heads perform.   The other thing that was the most valuable were the troubleshooting techniques, and 'rules of thumb' for maintaining the machines....

Cabinet OEMs generally do not build to stock, and therefore the lead times are typically 8+ weeks to manufacture and deliver. CSI carries the largest inventory of professionally decommissioned gas cabinets and panels in North America --500+ gas cabinets and 100+ panels – that enable us to quickly match systems that have been used on the same or gases in the same family.* Consequently, CSI’s lead time are much shorter -- typically 2 weeks. *Matching same or similar gases ensure that the new gas doesn’t react with the with any trace molecular residue that may have been absorbed in the seating materials...

We have been working with Critical Systems for about 2 years now.  The first order that we gave them was for a reconditioned HCl cabinet and a couple of Silane panels.   The next order was for a couple more cabinets that were needed in a hurry.  I recommended Critical Systems even though that facility had always bought new cabinets.   It was the right call – the cabinets were delivered on time, and were brought on line without any issues.   The latest order was for an emergency situation.  We had an abatement tool crash on us, and we were down.   They...
