Silver nanoparticles embedded in DLC matrix, were prepared by co-deposition of RF-Sputtering and RF-PECVD method from acetylene gas and sliver target. The RF power and initial pressure of chamber were fixed. Variations of morphology, optical and electrical properties of these films over time were investigated

Abstract Unprotected copper conductors are prone to oxidation and corrosion, especially when in contact with salt water or at high temperature. In this study, we compared commercially available coating graphene oxide plasma-enhanced chemical vapor deposition (PECVD) coated wires terms of antioxidation anticorrosion protection. Samples were subjected aging tests a spray chamber. Thereafter, both...

Firsts results on particle detection using a novel silicon pixel detector are presented. The sensor consists of an array of 48 squar pixels with 380 lm pitch based on a n–i–p hydrogenated amorphous silicon (a-Si:H) film deposited on top of a VLSI chip. Th deposition was performed by VHF-PECVD, which enables high rate deposition up to 2 nm/s. Direct particle detection using bet particles from Ni...

Techniques for cost-efficient operation of SiNx:H systems with a capability for hydrogen passivation in a manufacturing environment are analyzed. We conclude that SiNx:H performance may be optimized by a variety of techniques, and that the cost and productivity of the deposition tool may be the determining factors in the industry’s decision for a particular technique. PECVD constitutes the curr...

Due to its outstanding chemical stability and mechanical properties, silicon carbide (SiC) is one of the best materials for harsh environment applications. In this work, bulk micromachining technique was utilized to fabricate a PECVD SiC pressure sensor. This technique simplified the process and solved the stickiness problem in surface micromachining. The whole fabrication temperature is under ...
