Description

Oxford 80 Plus is an anisotropic dry etch tool. The main use of this tool is to etch SiO₂, and SiN_x to create hard masks for deep Si etch. However, it etches many other materials, including a variety of resists. The tool is connected to the following gases: Ar, O2, CF4, CHF3, SF6.

The plasma is ignited by the oscillating electric field created by the RF power at 13.56 MHz. The wafer is cooled down via passive cooling through a graphite chuck.

Applications

• Etch of SiO2
• Etch of SiNx
• Etch of Si
• Etch of resist
