Vertical-cavity surface-emitting laser chip bonding by surface-tension-driven self-assembly for optoelectronic heterogeneous integration
Yuka Ito,Takafumi Fukushima,Hisashi Kino,Kang-Wook Lee,Koji Choki,Tetsu Tanaka,Mitsumasa Koyanagi +6 more
TL;DR: In this paper, a 12-channel vertical-cavity surface-emitting laser (VCSEL) is self-assembled on Si and glass wafers using water surface tension as a driving force.
Journal ArticleDOI
High Level Oscillations With Narrow Linewidth in Magnetic Nano-Contact Spin Torque Oscillator With Synthetic AF Spin-Valve Structure
H. Endo,Tetsu Tanaka,Masaaki Doi,Susumu Hashimoto,Hiromi Fuke,Hitoshi Iwasaki,Masashi Sahashi +6 more
TL;DR: In this paper, the current induced magnetization dynamics, so called spin torque oscillation, in magnetic nano-contact MR element with a synthetic antiferromagnetic type spin-valve structure under high in-plane applied magnetic field of 0.9-1 kOe was investigated.
Proceedings ArticleDOI

K. W. Lee,C. Nagai,Jichoel Bea,Takafumi Fukushima,Tetsu Tanaka,Mitsumasa Koyanagi,R. Suresh,X. Wu Xilinx +7 more
TL;DR: In this article, the authors proposed a novel hybrid bonding technology with a high stacking yield using ultra-high density Cu nano-pillar (CNP) for exascale 2.5D/3D integration.
Journal ArticleDOI
Transcatheter aortic valve implantation in a patient with severe aortic valve stenosis, colon cancer, and obstructive ileus: A case report.
Tetsu Tanaka,Kazuyuki Yahagi,Taishi Okuno,Yu Horiuchi,Takayoshi Kusuhara,Motoi Yokozuka,Sumio Miura,Kengo Tanabe +7 more
TL;DR: TAVI could be useful for symptomatic severe AS in high-risk patients prior to non-cardiac surgery, especially for malignant tumors, and transcatheter aortic valve implantation may be a useful option to reduce the incidence of complications and the time to surgery for the malignancy.
Proceedings ArticleDOI
Revisiting the silicon-lattice in the high-density 3D-LSIs — In the perspective of device reliability
TL;DR: In this article, the dependence of device reliability on the lattice perfectness of the active silicon in the high-density 3D-LSIs containing through-silicon via (TSV) and microbump (μ-bump) is extensively investigated using hard X rays at SPring8.
