The SEMI Committee on Chemical Reagents began its efforts on etchants in 1979. With this publication, the Committee establishes definitions for three major types of etchant mixtures; mixed acid etchants, buffer oxide etchants, and phosphoric etchants. Specifications and analytical procedures are introduced for each type.

 

Etchants within all of the requirements can be described as "meeting SEMI Specifications."

 

Where an analytical procedure different from that provided is substituted by a supplier or user, the burden of proof is on said supplier or user to confirm the equivalency.
