General description

Nickel compatible gold etchant is an etching solution that can be used in the removal of the gold layer from the surface. Compatibility of gold etchants with nickel allows it to be utilized in applications where nickel is used as a dominant material in the fabrication of micro-electro-mechanical systems (MEMS).

Application

Elective general-purpose etchant for gold. Compatible with negative and positive photoresists.

Features and Benefits

Etching readily controlled with minimum undercutting. Room temperature operated. Cyanide-free, no attack of nickel films.
