Characteristics and limitation of scaled-down MOSFET's due to two-dimensional field effect
H. Masuda,Masaaki Nakai,M. Kubo +2 more
TL;DR: In this article, the authors investigated the practical limitations of minimum-size MOS-LSI devices through measurement of experimental devices and concluded that the smallest feasible device has a channel length of 0.52 µm and a gate oxide thickness of 9.4 nm when the supply voltage is 1.5 V.
Journal ArticleDOI
MOS area sensor: Part II—Low-noise MOS area sensor with antiblooming photodiodes
Shinya Ohba,Masaaki Nakai,Haruhisa Ando,S. Hanamura,S. Shimada,K. Satoh,K. Takahashi,M. Kubo,Tsutomu Fujita +8 more
TL;DR: In this article, a high-sensitivity 320 × 244 element MOS area sensor and a fixed pattern noise (FPN) suppressing circuit are reported, which is proved to stem mainly from inversion charge variations through horizontal switching MOS gate capacitances.
Patent
Protective circuit and device for metal-oxide-semiconductor field effect transistor and method for fabricating the device
TL;DR: In this paper, a metaloxide-semiconductor field effect transistor (MOSFET) is used to protect the gate and source of a high-speed operation, whereby the circuit is completed.
Patent
Analyzer having sensor with memory device
Satoshi Ozawa,Takafumi Kikuchi,Yoshiki Murakami,Masaaki Nakai,Koutarou Yamashita,Toshiko Fujii,Yuji Miyahara,Yoshio Watanabe +7 more
TL;DR: In this article, an analyzer includes an exchangeable and consumable element such as a sensor, column or reagent the characteristic of which specifies an analyzing condition, which is provided with a non-volatile semiconductor memory which holds the analyzing condition adapted for the element as data.
Journal ArticleDOI
