Semicon Etching Agents
DAIKIN provides high quaity etching agents for wet and dry fluorine types for semiconductor manufacturing.
DESCRIPTION
DAIKIN provides etching agents for wet and dry fluorine types for semiconductor manufacturing. For wet etching agents, we provide high quality products in which impurities such as metal-ions, etc., are minimized. We also handle grades with improved permeability and reduced particle adhesion onto wafers by adding a unique surfactant.
