PURPLE INNOVATIONS
FOR GREEN MANUFACTURING

Clean air technologies from DAS Environmental Experts.

Semiconductor manufacturers use a variety of high GWP gases to create intricate circuitry patterns upon silicon wafers and to rapidly clean chemical vapor deposition (CVD) tool chambers. Semiconductor manufacturing processes use high GWP fluorinated compounds .

Although the use of fluorinated GHGs did not begin until the late 1980s, their application facilitated the development of significantly more complex and faster processing semiconductors. The continued availability and use of these gases are considered to be critical to the future success of the industry.

Estimating fluorinated GHG emissions from semiconductor manufacture is complicated and has required a significant and coordinated effort by the industry and governments. It was historically assumed that the majority of these chemicals were consumed or transformed in the manufacturing process. It is now known that under normal operating conditions, anywhere between 10 to 80 percent of the fluorinated GHGs pass through the manufacturing tool chambers unreacted and are released into the air.

In addition, fluorinated GHG emissions vary depending on a number of factors, including gas used, type/brand of equipment used, company’s product, the specific process parameters, number of fluorinated GHG-using steps in a production process, generation of fluorinated GHG by-product chemicals, and whether appropriate abatement equipment has been installed.

DAS Solutions … Burn/Wet Systems

The combination of burning & scrubbing is used in several DAS products for the treatment of different dangerous and harmful waste gases. Our compact solutions have a small footprint and are easy to maintain. Operation costs and general safety can be optimised with a process tool interface.

 

ESCAPE

Our Basic System for Process Waste Gas Treatment

ESCAPE INLINE

The ESCAPE product line is the basis of our point-of-use burner-scrubber technology which is well-established for more than 25 years on the market. Gas Scrubber (burn/wet) offers flexible and customised applications for the abatement of almost all process waste gases in the semiconductor and photovoltaic industries. Media supply is variable.

 

STYRAX

Waste Gas Treatment for Waste Gases from Demanding CVD Processes

STYRAX DUO

The STYRAX product family was specifically developed to manage demanding waste processes like CVD processes in the semiconductor and photovoltaic industry. Our application specialists ensure customized configuration of the burn/wet system. In this way, media consumption can be adopted flexibly.

UPTIMUM

Waste Gas Treatment for Waste Gases from Demanding CVD Processes

UPTIMUM

The UPTIMUM product line has been designed for higher tool uptime especially in CVD processes in the semiconductor and solar industry. The product name UPTIMUM refers to the term “Uptime“ underlining the high availability of the burn/wet system. The tool can be applied to different applications.
