2. Silicon RIE using Inductively Coupled Plasma (ICP)

What is ICP?


TSV Etch

TSV Etch (ICP)

A TSV is a vertical electrical connection passing completely through the silicon wafer. The formation of this structure requires a highly anisotropic etch process, with silicon to resist selectivity high enough to allow for trenches with a depth of greater than 500µm.  This non-switched process can achieve etch rates 10µm/min.


Fast Switch Etch

Fast Switch Etch (ICP)

The process consists of two gasses that are active in the etching of silicon, the Etching Gas and the Passivation Gas, and can achieve etch rates over 10µm/min
