Description
- General description: Etching readily controlled with minimum undercutting. Room temperature operated. Cyanide-free for standard applications. Etch rate of 28 angstrom/sec @ 25 °C.
- Application: Gold etchant is a selective general-purpose etchant for gold, compatible with negative and positive photoresists. It is used to etch out gold (Au) electrodes prior to scanning electron microscopy (SEM) imaging for morphological study[2] and metal layer for the preparation of nanoelectrodes array.[3] Gold etchant can also be used in metal assisted chemical etching (MACE) for the fabrication of p-n junction silicon nanopillar based solar cells.[4]
