8 Top Universities with Plasma Processing Technology

8 Top Universities with Plasma Processing Technology

The Butterfly Project

Plasma processing technology (e.g., etching, PECVD, and CVD) is a crucial component of semiconductor manufacturing and nanotechnology. As semiconductors become increasingly common across materials and electronics applications, the use cases for plasma processing are constantly increasing. At the same time, nanotechnology is presenting itself as a significant body of research that promises to provide value across industries — both commercially and non-commercially.

It's increasingly common to see plasma processing equipment housed in university classrooms. This equipment provides students with real-world experience with technology that they may come into contact with in their future jobs. Plasma processing technology is also used by researchers across the globe who are interested in fields such as bio-nanotechnology, nano-materials, and semiconductors.

At CORIAL, we are proud to offer our technology to universities looking to provide tangible real-world and research opportunities to both undergraduates and graduates. Our parent company — Plasma-Therm — helps lead the plasma processing industry with its cutting edge plasma solutions. 

Recently, we took a look at some of the universities using Plasma-Therm's products. From Cambridge to Hong Kong to Harvard, here are how universities are leveraging Plasma-Therm quality to educate the next leaders in nanotechnology.

1. California NanoSystems Institute at UCLA 

The California NanoSystems Institute at the University of California, Los Angeles, provides training and lab equipment to students focused on excelling in nanotechnology and engineering.

Plasma-Therm's DRIE DSE II Silicon Etch machine uses the Bosch process to rapidly fast etch deep anisotropic trenches (with extremely high aspect ratios) in silicon substrates (e.g., SiO2,  Silicon, Si3N4, SiOxNy, and polymer films). The FDRIE DSE II has 3500 W of max power with >8 um / min etch rates, and the system can be controlled via the Windows-based software Cortex®.

2. Cambridge Graphene Centre

The Cambridge Graphene Centre is a research center at the University of Cambridge that explores graphene, layered crystals, and Hybrid nanomaterials. As part of their Class 1,000 clean room, Cambridge offers three Plasma-Therm models:

  • Advanced Vacuum's SLR: A load-locked system for inductively coupled plasma - reactive ion etching using etchants such as Si, SiO2, and Si3N4.
  • Advanced Vacuum's Vision 310 PECVD: A plasma-enhanced chemical vapor deposition system for semiconductor fabrication with a 305mm substrate platen and temperature electrodes of up to 380°C.
  • Advanced Vacuum's Vision 320: A reactive ion etcher with a 305mm substrate platen and an extensive etch process library capable of etching polymers, metals, dielectrics, and compound semiconductors.

3. City University of Hong Kong

City University of Hong Kong has a longstanding reputation in the material sciences. From being listed as one of China's Top 100 Material Science units to helping students learn and embrace the future of nanotechnology, City University continues to provide ample education and resources to its students. City University currently uses a Oxford Plasma-Therm 790 RIE System for plasma etching projects.

About the Plasma-Therm 790 RIE:

Plasma-Therm's 790 RIE is a Reactive Ion Etching (RIE) machine with water-cooled RF platen and showerhead gas distribution. The 790 has a four-gas chamber (CF4, CHF3, SF6 and O2)  that can be controlled directly from the MFC. It can etch single substrates up to 200mm in diameter, and it has a 500W 13.56 MHz RF generator with a turbo pumped vacuum system with rough pumping.

4. Cornell University - NanoScale Science and Technology Facility

Cornell University's NanoScale Science and Technology Facility (CNF) is a world-class micro and nanofabrication facility. Cornell commissioned a chlorine-based dual-chamber Plasma-Therm 720/740 in 2018. Recently, they also partnered with Plasma-Therm to commission an advanced atomic layer etching (ALE) for nanoscale device fabrication.

About the Plasma-Therm 720/740 Dual Chamber RIE System:

Plasma-Therm's 720/740 Dual-Chamber RIE System can be used to etch 2d tradition metal chalcogenides. It's load locked with turbo pump chambers and it comes with a Neslab HX-75 chiller. The 720/740 can cut wafers up to 8".

5. Harvard University - Center for Nanoscale Systems

Harvard University's Center of Nanoscale Systems (CNS) is a shared-use facility at Harvard that focuses on nanotechnology and its applied applications to larger systems. CNS focuses on generating world-class research for both public and commercial use, and they currently have one of the world's premier equipment lockers to help them tackle these problems. While Harvard has a plethora of plasma equipment, the Plasma-Therm Diamond RIE (RIE-11) stands out.

Plasma-Therm Diamond RIE:

Plasma-Therm's Versaline Inductive Coupled Plasma (ICP) etching system produces stable and repeatable etching results across a variety of materials. With an ICP RF of up to 1,200 W and an RF bias of up to 600W, the Diamond RIE is an incredibly powerful offering in the plasma etching market. It has diamond etching capabilities with an O2 plasma chamber and substrate temperatures of up to 10 °C to 180 °C. Other features include mechanical clamping and backside helium cooling, as well as the ability to temperature control (up to 180 °C) the lid, ceramic spool, and metal liner.

6. McGill University - Institute for Advanced Materials

The McGill University Institute for Advanced Materials focuses on discovering, creating, and advancing advanced materials — including nanomaterials using microfabrication. MIMA houses a variety of equipment for use with nanofabrication, including the PlasmaTherm SLR for dry etching projects.

About the Plasma-Therm SLR:

The Plasma-Therm SLR is an ICP machine used for high-quality ICP etch applications. This semiconductor etcher is load-locked and has multiple gas chambers (Cl2, O2, H2, N2, and Ar) — giving it the ability to operate between 0-100 mTorr. The SLR is available in several models, including some similar models offered by CORIAL for both low-volume and high-volume environments.
