The Quartz Baths designed and manufactured by Modutek Corporation are safe and reliable as well as being cost-effective so it can be integrated into your current production system. With over 30 years of experience developing and evolving the bath designs, they are seen in the industry as the quality standard of quartz baths.

Pure quartz is nearly inert and will not react with most other substances. It is for this reason quartz is the perfect choice for semiconductor processes. Not only is it non-reactive, it is also stable at relatively high temperatures. It has a Mohs hardness of 7 and lacks cleavage which enables it to handle most demanding applications.

Modutek offers different Quartz Bath Products to meet your processing needs:

The QFa Series Quartz Baths provide the following benefits:

• Fast heating that is more even than other manufacturers
• A nested, 4-sided heating element that heats to 360 degrees Fahrenheit with a serrated overflow barrier
• A seamless, sloped flange design
• Minimizes damages which could result from runaway temperatures
• Dual safety snap switch
• Improved up-time and reliability because of the longer vessel life
• Easier laminar flow while it reduces particulate contamination

It can be used with a variety of chemicals including H2SO4, H202, SC1 and other chemicals. It has an operating range of 30 º – 180 ºC. The operating temperature range can be controlled in ± 1 ºC (depends on controller and process). The operating temperature range has a heat-up rate of 2 º C per minute. (This rate will be affected by the size of the system, the fluid being used and other factors.) It can be used for cleaning, etching and stripping and has a ¾” male Flaretek circulating fluid inlet/outlet.

Options include a liquid level sensor, process temperature controller, custom vessel sizes to meet your specifications, quartz diffuser plate and autolid.

The Qa Series Quartz Bath is a constant temperature quartz bath. It has redundant safety devices, seamless, sloped flange design and a bonded, 5-sided circuit heating element. Benefits include improved process yield by faster, more efficient, and even heating. It minimizes the potential damage caused by runaway temperatures. It also increases uptime and reliability because of longer vessel life.

The options available for the Qa Series Quartz Baths include having a magnetic stirrer, a gravity drain, an aspirator (dilution) valve system, remote operation timer switches, quartz bubbler, and process controller.

Both Series Quartz Baths come in a variety of sizes. If you would like to learn more about the Modutek Corporation Quartz Bath models or want a quote, you may reach us at 866-803-1533.
