Monolithic 3D Integration of III-V HEMTs on Glass Using Ultra-Thin Dielectric Bonding Layer: A High-Frequency and Low-Loss Active Glass Platform for Sub-THz Applications
Jaeyong Jeong, Yurim Choi, Seongju Kim, Hyeongjun Kim, Jimin Kwon, Sanghyeon Kim

The growing demand for sub-THz wireless systems requires not only high-frequency RF devices but also compact, low-loss integration platforms. In this work, we demonstrate a monolithic III-V/glass RF platform using a low-temperature wafer bonding technique, where III-V enables high-frequency transistors and glass offers a low-loss, low-cost, and dimensionally stable platform. The InGaAs HEMTs fabricated on a glass substrate achieve f<inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink=

Two-dimensional (2D) indium selenide (In2Se3) has great potential for next-generation processing-in-memory applications owing to high intrinsic carrier mobility and strong ferroelectricity. However, the lack of wafer-scale, back-end-of-line (BEOL) compatible growth and inherent polarization-induced hysteresis limit their viability in logic circuits. Here, we report thermal evaporation of a non-ferroelectric κ-phase In2Se3 film that forms uniformly over 4-inch wafer-scale at <450 °C. Structural c

Oxygen‐Tunnel Indium Tin Oxide Vertical Channel Transistors with Enhanced Current Density and Reliability for Monolithic 3D Compute‐In‐Memory Systems

SJR Q1Advanced Functional MaterialsOA

ABSTRACT Monolithic three‐dimensional integration demands embedded memory technologies that achieve extreme density scaling under limited back‐end‐of‐line thermal budget. Atomic layer deposition‐grown amorphous oxide semiconductors (AOS) are attractive for this purpose because of their excellent conformality and intrinsically low off‐state current I OFF, enabling vertical channel transistors (VCTs) for capacitor‐less gain‐cell memory operation. However, in VCT, oxygen‐deficient AOS channels requ

SJR Q1Advanced Functional MaterialsOA

ABSTRACT Atomically thin 2D semiconductors enable excellent electrostatic control even in highly scaled transistors with few‐nanometer gate lengths. The electrical characteristics of 2D transistors can vary significantly with the number of layers, yet how device behavior evolves with channel thickness remains statistically unexplored. This limitation mainly arises from the difficulty of obtaining large numbers of single‐crystal flakes with well‐controlled thickness and fabricating devices. Here,

Statistically Resolving Thickness‐Dependent Electrical Characteristics in Multilayer‐MoS 2 Transistors (Adv. Funct. Mater. 45/2026)

Single-Flake Transistor In the Research Article (DOI: 10.1002/adfm.202532204), Yongwoo Lee, Haksoon Jung, Jimin Kwon, and co-workers demonstrate that 3-8 layer MoS2 flakes can be reliably classified using pixel intensity contrast in the red, green, and blue optical channels. This approach enables large-scale correlation between optically identified layer number and electrical characteristics, providing a foundation for statistically resolving thickness-dependent electrical behavior in 2D transis

Active BSCDN Benchmark Framework with Backside-Compatible CNFET Logic Technology
Yehyun Shin, Ikkyum Kim, Minho Park, Junghyun Yoon, Seunghun Baek, Seongmin Eum, Heesoo Yang, Yurim Choi, Jaeyong Jeong, Sanghyeon Kim, Haksoon Jung, Seongju Kim

This study presents a benchmark framework for digital blocks featuring an active backside clock distribution network (BSCDN), which incorporates clock buffers and sinks implemented using backside-compatible logic based on carbon nanotube field-effect transistors (CNFETs). The proposed framework includes the fabrication, characterization and TCAD modeling of complementary CNFETs, neural network-based compact modeling, standard cell characterization, and a block-level benchmark comparing the perfo
