A comparative study of MOS structures metallized in planar and cylindrical magnetron systems and in a conventional d.c. diode sputtering system was conducted. In all cases the influence of the discharge led to distortion and hysteresis in high freque

A charge-based DLTS technique is proposed for characterizing the interface states and, with some restrictions, the bulk traps in MIS, p–n, and Schottky-barrier diodes. The technique uses very simple devices — a mechanical chopper and a standard e

A1N films were deposited onto silicon substrates in d.c. planar magnetron system by means of reactive sputtering of aluminium in an atmosphere of nitrogen. The influence of the deposition conditions and of post-deposition annealing on the properties

The variation of the fixed oxide charge and the surface state densiy concentration are investigated in MOS structures under γ-irradiation from a 60Co source. SiO2 in the studied samples was obtained in a planar plasma reactor at low temperature (300

Different sources of error are discussed for the case of the use of a static technique to determine the interface state density in MOS systems. A direct Q–U analysis is recommended in order to eliminate the error when numerical differentiation is u

Stripping of different types of photoresist in O2 plasma in a planar reactor is investigated. Data are presented on the dependence of the stripping rate on the O2 pressure, temperature, and power density. Also, contamination by residues from the phot

SiO2 layers on Si substrates are obtained in planar reactor by decomposition of tetra-ethoxy silane in oxygen plasma. The layers deposited at substrate temperature of 300 °C show some porosity, hygroscopicity, increased etching rate, and water incor

The radiation damage in a Si-SiO2 system exposed to O2 plasma in a planar reactor is investigated in dependence on the exposure time, the substrate temperature, and the pressure of O2. Capacitance-voltage (C-U) techniques and a static method are used
