Background:

Wireless communication penetrates nearly all aspects of our daily life. Whether we're streaming music while running, checking the latest news on our smartphones, or monitoring home security through IoT devices, wireless technology is there to provide connectivity with maximum mobility. Current 5G wireless utilizes a frequency band up to 71 GHz, and further scaling requires exploitation of even higher frequencies (e.g., beyond 200GHz). A new semiconductor technology for signal processing is thus demanded. One key challenge is to make good high-gain, low-noise amplifiers that operate in the 200-300 GHz frequency band.

Research goal:

The world's best low-noise amplifiers are made with InP-based high electron mobility transistors (HEMT), due to the excellent electron transport properties of the lattice-matched InGaAs material. To operate at such high frequencies, accurate epitaxy control, extra fine sub-100 nm gate length, and aggressive dielectric thickness scaling are needed. Currently, these requirements impose challenges on the mass adoption of this technology, as usually EBL is needed. At TU/e, we aim to address the problem with state-of-the-art mass manufacturing technologies. The first step involves the essential steps toward high manufacturability, utilizing our in-house ASML DUV scanner. The second stage will be an exploration of a sustained scaling path, including MOS-HEMTs with high-k dielectrics and advanced device architecture. In this project, you will be at the very core of the development of a new revolutionary semiconductor technology for future wireless. The project involves the full value chain in high-frequency devices - from epitaxy to simulation, fabrication, and characterization.

The project is part of the collaborative project with NXP and the IC group at TU Eindhoven, named 'Future Wireless Interfaces (FWITEC)'. The project is aimed beyond 5G communication technology and focuses on the application of using wireless interconnect to replace physical links. They encompass short-range inter-chip and intra-chiplet communication, in-package communication up to in-house/in-production-line line-of-sight (<10m) device-to-device communication. This is projected as a future high-volume application, with a potential B$ market value. In this project, you will be employed at the Photonic Integration group (PhI), and have the opportunity to work with experts from NXP and the IC group.

About us

The Photonic Integration (PhI) group at TU/e has a long track record of setting pioneering results in indium phosphide (InP) based semiconductor technology. The group initially focused on InP photonics, but now also includes InP electronics, by leveraging the well-established and highly transferable semiconductor expertise. Our group consists of approximately 80 members, including 8 permanent faculty members, each specializing in a different technology vector. We are a key player in the field, as evidenced by our founding and coordinating role in the globally leading Joint European Platform for photonic integrated components and circuits JePPIX. We take a leading role in driving InP-based semiconductor technology towards the next level. A key enabler for our work is our state-of-the-art Nanolab cleanroom facility, which specializes in III-V materials processing.

Eindhoven University of Technology is an internationally top-ranking university in the Netherlands that combines scientific curiosity with a hands-on attitude. Our spirit of collaboration translates into an open culture and a top-five position in collaborating with advanced industries. Fundamental knowledge enables us to design solutions for the highly complex problems of today and tomorrow. Some impressions of our photonics research can be seen in this video.
