In this study the bending reliability of an isotropic conductive adhesive (ICA) filled between two printed circuit foils (PCF) as interconnection for a System-in-Foil is evaluated. The filling is realized by a Jet-Dispense process on oxygen plasma treated, as well as non-plasma treated foils. The samples are tested on a bending test setup capable of real-time electrical measurements during bending...
Nanodiamonds (NDs) are often considered as inert platforms with high interests for biomedical applications. They are well adapted for drug delivery, and may display embedded fluorescence. We report here on a new way to consider these nanocarbon particles, by revealing therapeutic capacities coming from electronic properties of NDs. With an optimized surface chemistry, the generation of Reactive Oxygen...
The search for extraterrestrial life is one of the most challenging science topics for the next decades. Space missions, like ExoMars, plan to land and search for biological remnants on planets and moons in our nearby Solar system. Planetary protection regulations defined by COSPAR prevent that during the mission biological contamination of the bodies occur through the space probes. Therefore decontamination...
This paper presents XPS depth profiling study on the materials used in amorphous indium-gallium-zinc oxide thin-film transistors (a-IGZO TFTs) having Ti and Mo source/drain (S/D) electrodes. The XPS results suggest that there are some differences between Ti/a-IGZO and Mo/a-IGZO interface regions for the chemical states of the materials. The chemical states of the back-channel surfaces are also found...
This paper introduces the preliminary results of developing a spider-inspired hydrophobic hairy structure for air shield forming underwater. A fabrication procedure is proposed for rapid production of samples in various hair densities. The samples can form dry islands in a puddle of water. Wetting tests are performed to confirm the importance of hair density and water kinetics. Further analysis of...
Tungsten coating has been electrodeposited form Na2WO4-ZnO-WO3 molten salts in an open air condition. The electro-chemical mechanism of tungsten in such molten salts has been studied by cyclic voltametry and chrono-amperometryt. It has been found that a cathode reduction peak appears at a potential of about 700 micro-volt (vs platinum quasi-reference electrode) and the outcome of iso-potential electrolysis...
A The developing of green remanufacturing for vehicle engine was introduced briefly. Based on the analyzing of key part's failure mode and remanufacturing of armored vehicle engine this paper introduced the remanufacturing technology program for a tank diesel engine and introduced a preliminary evaluation criterion which is an exploratory development for the construction of index system on there manufacturing...
Plasma immersion ion implantation (PBII) has been regarded as an effective tool to enhance surface properties. The implantation dynamics during plasma ion implantation of small component used in micro-electromechanical systems (MEMS) has seldom been investigated. Numerical simulation of PBII by Particle-in-cell/Monte Carlo collision method has been launched to understand the effect of small target...
Passivation of interfaces corresponding to the nanoposts' sidewalls in InP-based intersubband quantum-box (IQB) lasers has resulted in interfacial-state densities < 1011/cm2. High-quality regrowths of semi-insulating InP around dry-etched, passivated, 40 nm-diameter nanoposts were realized.
In this article we demonstrated a way to transport droplets by an arrowed micro-pillar array surface with hydrophobic parylene. We developed successfully that the lightly hydrophilic parylene surface can be changed to hydrophobic one treated with fluorine-based plasma (CF4 and SF6) for 10 seconds. Otherwise, we designed the ratchet pattern similar to the one proposed by A. Shasty in 2007. The droplet...
The structural integrity of polymeric interfaces has been critical in enabling microelectronic applications. This paper demonstrates a systematic approach in investigating the strengthening of the polymeric interface between a thinly deposited polysiloxane optical cladding deposited onto flexible substrate. The surface of the polyimide substrate was modified with plasma treatment. Surface properties...
The interaction of streams of charged particles and plasma streams with structural materials is connected with implementation of the wide range of processes: collisional, thermophysical, thermomecanical, thermal fatigue, diffusive, thermo-chemical and plasma-chemical. Now there are works taking into account these factors and, especially, their interrelation. All these processes influence both character...
In this contribution we report on plasma modification of natural textile fibres, like raw wool and wool yarn and cotton wool and cotton yarn. Radiofrequency plasmas (13.56 MHz) generated in parallel plate configuration at low pressure and in dielectric barrier discharge (DBD) configuration at atmospheric pressure have been used. At low pressure the samples were treated at different times (1-30 min)...
Stretchable electronics consist of a stretchable substrate material with embedded electronic components connected by electronic interconnections. Since little or no stretchable electronic components are available, it is vital to engineer electronic interconnections which are stretchable. Today metals (copper, nickel and gold) are the best option to realize the interconnections with high performance...
Novel 3D stacked gate-all-around multichannel CMOS architectures were developed to propose low leakage solutions and new design opportunities for sub-32 nm nodes. Those architectures offer specific advantages compared to other planar or non planar CMOS devices. In particular, ultra-low IOFF (< 20 pA/mum) and high ION (> 2.2 mA/mum) were demonstrated. Moreover, those transistors do not suffer...
Plasma-exposed Si surface related to Si recess in source/drain region was investigated in detail for various superposed bias configurations with frequencies of 13.56 MHz and 400 kHz. Two different bias powers were utilized by an inductively coupled plasma reactor (ICP). The surface layer (SL) and the interfacial layer between the SL and Si substrate (IL) were analyzed by spectroscopic ellipsometry...
Summary form only given. Selective etching technology has been developed for selective removal of surface layer of polymer on micro and nano polymer matrix composites, leaving fillings virtually intact. This technology is useful for the coatings and composite industry for quality control of the product or in electronic industry for developing new nano-based sensor devices, and also elseware. The two...

Field emission cathodes consisting of cesium iodide (CsI) coated graphite fibers have been investigated as promising electron sources for high power microwave (HPM) devices. After conditioning for removing adsorbed water vapor, these cathodes have operated stably for more than one million pulses and release little or no plasma. One of the most useful properties of the Csl coatings appears to be a...
