SACHEM is committed to caring for the environment and efficient use of resources.
By combining our chemical science expertise and technology SACHEM has created
the Mobius System™, an innovative recycle technology.

Recycling tetramethylammonium hydroxide (TMAH) used to be an expensive and inefficient process.  Large bio-treatment ponds were needed to handle the high COD and BOD demand it takes to break down TMAH waste – restricting a fab’s capacity and space.  And shipping TMAH waste offsite for disposal was a costly and tedious alternative. 

But now there’s a better way. 

Ideal for TFT/LCD production, the SACHEM Mobius System ™ represents a huge leap forward to TMAH recycling technology. 

With the Mobius System™ you will: 

Increase Your Capacity
·         recover up to 99.95% of TMAH back to high purity grade
·         capture very dilute waste streams of TMAH and recycles on-site back to developer or as
          concentrate.
·         eliminate restrictions on bio-treatment or waste disposal caused by TMAH 

Save Money
·         eliminate cost of disposal
·         lower the total cost for lithography developing
·         reduce transportation costs 

Reduce Water Consumption
·         recycle a minimum of 85% of the water lost in developer systems 

Go Green
·         reduce carbon footprint by resuing an organic molecule many times over
·         reduce the carbon emissions associated with manufacturing and transporting
          virgin TMAH 

Tests prove that developers made from the SACHEM Mobius System ™ perform as well as developers made from virgin TMAH.
