System Information:

General Description:

This system use reactive ion etching techniques to anisotropically etch a wide variety of substrates.


The Panasonic E620 is a dry etching system which generates up to 1250 watt inductively coupled RF plasma at 13.56 Mhz and up to a 600 watt capacitive bias for highly anisotropic etches. It has the ability use, Ar/CHF3 and CF4/SF6 on shared gas lines, Cl2, N2, O2, and BCl3 as process gasses, allowing for etching of a large variety of materials.
The E620 accepts single flat 6” wafers and uses an electrostatic chuck along with helium backside cooling. Additional features include end point monitoring, error logging and a simple interface with storage for 99 recipes.


• Gold and platinum are not to be processed in the Panasonic.
• There is a 100g weight limit for the wafer to be loaded into the system.
• Any new materials or use of BCl3 must be approved by BNC Staff
