The incorporation of this system not only expands the variety of materials subject to effective etching and manipulation but also encourages collaborative research initiatives and experimentation, thus reinforcing MIT.nano’s objective to facilitate and advance high-impact scientific research.
Reactive-ion etching is a sophisticated material removal process performed under low pressure, in which a highly reactive plasma is generated to meticulously remove the material on the substrate. This method is particularly valued in semiconductor fabrication, as it allows for precise control over the etching profile and selectivity of materials.
With inductively coupled plasma RIE, the plasma is generated by a radio-frequency-powered magnetic field to ionize different gases, producing a high-density plasma that effectively enhances the etching rate and uniformity across complex patterns.

The combination of chemical reactivity and physical bombardment from ions enables the removal of materials with a high degree of accuracy, making it essential for creating intricate micro-structures in various electronic devices. Furthermore, the ability to adjust the gas composition and power settings allows for fine-tuning of the etching process, thereby optimizing performance for specific applications and materials.
The etching of different materials is artfully influenced by the type and amount of gas used, ensuring that any volatile byproducts are efficiently removed in the effluent.
The SAMCO RIE-230iP ICP etcher masterfully integrates fluorine, chlorine, and bromine chemistries from 11 diverse process gases, empowering broad etching capabilities for a wide array of innovative materials and research endeavors.
With its advanced load-lock system, the reaction chamber maintains a vacuum during substrate loading and unloading, fostering not only enhanced process repeatability and throughput but also ensuring a safer environment for working with corrosive gases.

“The new SAMCO etcher’s ability to handle a range of materials gives researchers more flexibility in the choice of substrates and films for their devices,” says Jorg Scholvin, assistant director of user services at Fab. nano.
It will significantly expand the process capabilities available at MIT.nano, particularly when exploring new types of materials and devices.
The SAMCO RIE etcher adds two new etch chemistries, hydrogen bromide and nitrogen trifluoride, in addition to enabling the mixing of chemistries. It can process samples as small as a few millimeters, or wafers up to 8 inches in diameter. Nitrogen trifluoride was added for improved chamber cleaning between etch chemistries and different substrate materials.
Another feature of this tool is the built-in optical endpoint spectrometer (OES), which tracks the plasma and gas outputs, informing the researcher when etching is finished. The OES detects etched material through the optical spectrum; when the signal fades, all material has been removed.
The tool also includes a circulator for controlling substrate temperature from 20 degrees Celsius to 200 C, which is essential because some etching byproducts need to be heated to a higher temperature to become volatile.
