The paper presents the experimental results obtained in manufacturing of micro and nano-optical components using electron beam lithography (EBL) in a mono or multi-layer resist, lift-off and the soft lithographic techniques to transfer high-resolution patterns into other materials. The pattern from the master fabricated by EBL was transferred onto an(More)
This paper presents the results of an experimental study regarding the increase in the efficiency of the silicon solar cells, using various methods for texturing the front surface. Designing, patterning and surface etching processes led to obtain reined structures with very low losses of the incident optical radiation. This paper aims to compare the(More)
The paper presents the microfabrication technique of an integrated microsystem able to be used for power semiconductor devices air forced cooling. The paper studies the as obtained silicon microfluidic devices, their characteristics and applications. This technology for silicon surface microprocessing, uses a thick resist (≫20 µm) as a(More)
This paper presents the solar cells fabrication on multicrystalline silicon substrate with maximum efficiency of 13% by laboratory technology and main equipments used to characterization of such devices. The main objective was the minimizing the production cost maintaining the device performances. For these reasons the general concept of the technology(More)
The usual electrodes from electrophysiology are resistive. A variable metal-skin contact resistance frequently generates unpleasant artifacts. The capacitive electrodes avoid this disadvantage and are suitable for variable biosignals recording. The main novelty of this paper is the manufacturing of capacitive electrodes with all terminals on the top(More)
