### ** History of DRC**
The Device Research Conference (DRC) began in the pre-transistor era with the 1942 establishment of the Conference on Electron Device Research (CEDR). Following William Shockley’s 1948 CEDR presentation of the transistor device, the Solid-State Device Research Conference (SSDRC) was established, with invitation-only attendance.

In the ensuing decades, many exciting firsts were presented at SSDRC, including the use of impurity diffusion in silicon and germanium, the first practical MOSFET, and the first lattice-matched heterojunction.

In 1969, under the leadership or Herbert Kroemer and Cal Quate, the CEDR and SSDRC merged into DRC. In 1970, attendance was opened to all, and the first DRAM (dynamic random-access memory), room temperature lasers, and first CCD (charge-coupled device) were reported—all in the same 1970 DRC meeting!

1976 saw the first official coordination of tandem meetings between DRC and the Electronic Materials Conference (EMC) to bring together the electronic materials and device communities—a custom which persists to this day. In 1991, DRC began publishing its digest with IEEE; they can all be found [here on IEEE Xplore](https://ieeexplore.ieee.org/xpl/conhome/1000199/all-proceedings). Throughout this period, DRC featured reports of many novel and record-setting devices, including the HEMT (High Electron Mobility Transistor), VCSEL (Vertical Cavity Surface Emitting Laser), HBT (Heterojunction Bipolar Transistor), and nanoscale MOSFETs.

In recent years, DRC has continued to be the world’s premier forum to present innovative semiconductor device research with work on organic thin film transistors, graphene and carbon nanotube transistors, and 2D materials all featuring prominently in the 1990s through to the present day. In 2017, we celebrated DRC’s 75th anniversary with special sessions and an [article in the Journal of the Electron Device Society](https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=8168249&isnumber=8232486). DRC technical topics continue to evolve with emerging device trends such as memory devices, quantum devices, optoelectronics/photonics, and wide bandgap power devices to reflect the exciting work being done by a diverse community of device engineers around the globe.

Today, as we look forward to the next 75+ years of device innovation, DRC continues to lead the way in showcasing top-caliber research, facilitating vibrant discussion and debate and acting as a platform to nurture the next generation of device engineers. We welcome you to join us at the next DRC!

technical paper

We have investigated the effect of Si surface atomically flattening on the memory characteristics of MFSFETs utilizing ferroelectric HfN (Fe-HfN) gate insulator for analog memory application. The Fe-HfN does not form the interfacial layer so that the Si surface flatness directly affects to the MFSFET characteristics. Not only the static and memory characteristics but the low-frequency noise characteristics of MFSFET were significantly improved by the Si surface atomically flattening which is important for the analog memory application.

MFSFET with Ferroelectric HfN for Analog Memory Application


Based on DFT and NEGF computation, we explored that Ar and N2 do not
change captured properties of pristine graphene devices. However, they can influence the captured properties of graphene with point defects like carbon vacancy and stone wales defect, which are present inherently in the material. Thus, we can say that Ar and N2 gas
does not provide a completely inert environment for graphene.



Late News: Are Argon and Nitrogen Gases Really Inert to Graphene Devices

Gallium Oxide is an emerging ultra-wide band gap semiconductor with promising material properties relevant for high performance power electronic devices. State-of-the-art electron mobilities, contact resistance values, breakdown voltages and power figures of merit are demonstrated in β-Ga2O3 epitaxial films and devices.

High Performance Homoepitaxial Gallium Oxide Power Devices on Bulk and Composite Substrates

A Superconducting nanowire (ScNW) is among the most promising superconducting devices with possible applications in several avenues of cryogenic electronics. Recent demonstrations proved that the ScNWs can be utilized to design cryogenic oscillators, with possible usage in cryo-neuromorphic systems. The dynamics of the ScNW oscillator is unlike any other non-SC oscillator. Hence, a systematic design space expiration is highly necessary. In this work, we conduct a simulation-based study of the ScNW oscillators to identify the material/device-circuit co-design opportunities.

Design Space Analysis of Superconducting Nanowire-based Cryogenic Oscillators

Up-scaling of quantum information processors requires the cryogenic control CMOS devices to be operated in the few millivolt regime. However, MOSFETs show inverse subthreshold slope SS values which saturate well above the theoretical Boltzmann limit at cryogenic temperatures. In addition to this saturation of SS caused by band tailing, inflection degrades SS as a function of the gate voltage. We show gate stack engineering as an approach to counteract those phenomena which facilitate the realization of steep slope cryogenic MOSFETs.

Interface Engineering for Steep Slope Cryogenic MOSFETs

We report in this work the GaN camel diode varactors which show good breakdown voltage, low reverse current density and good quality factor. This varactor technology combining has potential to be applied to RF front-ends where high power handling capability is imperative.

Free-Standing High Power GaN Multi-Fin Camel Diode Varactors

This work reports the first radio frequency (RF) characterization of ultra-thin ALD-grown amorphous indium oxide transistors down to 150 nm channel lengths. Record RF performance among amorphous oxide semiconductors is achieved including operation up to 22 GHz.
