We describe uncooled infrared focal plane arrays (IRFPAs), which consist of pn junction diodes fabricated on a silicon-on-insulator (SOI) layer using a complementary metal oxide semiconductor (CMOS) process. Based on this technique, we released the M

We developed silicon-on-insulator (SOI) diode-based uncooled infrared focal plane arrays (IRFPAs), in which single-crystal pn junction diodes formed in an SOI layer are used as temperature sensors. These diodes, based on silicon large-scale integrati

In this study, we develop a shutter-less algorithm for a silicon-on-insulator (SOI) diode uncooled infrared focal plane array (IRFPA). The optimal non-uniformity correction is calculated onboard. The effectiveness of the proposed algorithm was verifi

We develop a shutter-less method for replacing mechanical shutters. To verify the effectiveness of the proposed method, we fabricated a silicon-on-insulator (SOI) diode uncooled 320 × 240 infrared focal plane array (IRFPA) with 17 μm pixel pitch ut

We found that the offset field (H off ) of a top-pinned magnetic tunnel junction (MTJ) with a CoPd/Ru/Ta/CoFeB-synthetic antiferromagnetic (SAF) free layer can be reduced by controlling the exchange coupling energy (J ex ) value. A micromagnetic simu

Synthetic antiferromagnetic (SAF) free layers consisting of [Co (0.3 nm)/Pd (0.7 nm)]n/Ru/Ta/CoFeB were investigated for use in the free layers of top-pinned magnetic tunnel junctions (MTJs). We found that interlayer exchange coupling properly provid

We applied Co20Fe60B20 layers with thicknesses from 1.2 to 1.5 nm to the sensing layers of MgO based magnetic tunnel junctions (MTJs) with spin-valve-type structures annealed at 350 °C for magnetic field sensors. The CoFeB layer on MgO had in-plane

We have investigated (Ba,Sr)TiO 3 (BST) films grown on Ru by a liquid source chemical vapor deposition (CVD). Inductively coupled plasma mass spectrometry (ICP-MS) analysis revealed the decline of (Ba+Sr)/Ti molar ratio of the initial BST-layer on Ru
