Dry Etching
Dry etching is a key step in device fabrication where layers or selected areas of material are removed by employing a plasma of reactive gases. The MRL offers several dry etching tools applicable to a variety of layers and substrate types and sizes.

(*) Discuss with staff before actually using any of those materials and if other materials are needed in the process. This is required for new and existing experienced users.
(**) Etching rate and quality will depend on several factors (type of material, sample thickness, pattern details, masking parameters, etc.). A discussion with staff is important in order to decide tool assignment and feasibility.

| Nano-Master Reactive Ion Etch (RIE) Plasma System |
|
342 MRL |
Nano-master NPC 3000 is a bench-top Reactive Ion Etching (RIE) system with showerhead gas distribution and water cooled RF platen. It is designed to meet a wide range of needs including sample cleaning, photoresist stripping, surface modification, polymer etching and silicon etching. The chamber opens from the top for wafer loading or unloading. It can accept up to 8" (200 mm) wafers. |
| Plasma-Therm 790 MF Reactive Ion Etch (RIE) Plasma System |
|
342 MRL |
Plasma-therm 790 MF is a stand-alone Reactive Ion Etching (RIE) system with showerhead gas distribution and water cooled RF platen. The chamber could reach a base pressure in the 3x10-5Torr range, and it can be operated in the pressure range of 10mTorr to 100mTorr. The following gases are installed: CF4, CHF3, SF6 and O2.The flow rate for each gas is set by a mass-flow controller (MFC), and the pressure is controlled separately by a throttle valve between the chamber and the pump. All system functions are controlled from the computer. The control program has both manual and automatic modes. |
