Avantor Performance Materials, formerly Mallinckrodt Baker, has entered a joint development agreement with Sachem to provide etching chemicals to the semiconductor industry. The firms will focus on surface preparation and removal chemistries for thin-film wafer stacks, combining Avantor’s experience in photoresist and residue removal with Sachem’s expertise in bulk etchants and surface preparation.
