TMAH FOR DISPLAY APPLICATIONS
Purity, consistency and service have been the hallmarks of SACHEM’s high purity Tetramethylammonium Hydroxide (TMAH), propelling us to a position of world leadership. 

We offer:
  • Exacting specifications, customized to each customer’s application
  • Flexible packaging to meet individual requirements
  • Synergies between SACHEM’s TMAH recycle technologies and virgin TMAH
  • Revolutionary service and support
From our world class manufacturing and packaging facilities in Texas and Japan and our newest manufacturing plant in Wuxi, China, SACHEM supports the flat panel display industry with strong economics and high quality TMAH products.  Drawing from our position of worldwide TMAH leadership, we are continuing to invest in manufacturing and recycle technologies which will make SACHEM and our partners the most competitive players in the world.

SACHEM also offers The Mobius System™, a TMAH recycling service which is a ‘Green' alternative to traditional TMAH waste disposal techniques currently in use by semiconductor and LCD producers, while offering an overall lower cost of ownership for lithography developing.  The technology is capable of capturing a wide range of TMAH waste streams through on-site installation thus allowing Fabs to bypass the need for further waste processing such as concentration and bio-treatment.  Through on-site recycling, the Mobius System™ assures users of a steady supply of high purity TMAH, reduced environmental impact and a lower overall cost of ownership.
