We contribute with this paper to the understanding of positive charge build up upon hole injection in SiO 2 known to be an important degradation process. Our results are in agreement with a recently proposed model of charge generation [4,6] . We have

We have studied SIMOX buried oxide samples implanted with D + (10 14 –10 15 cm −2 ) or annealed in D 2 (300–500 kPa at 1073 K). Thermal desorption spectrometry (TDS) performed on these samples after removal of the top Si layer shows two main pe

The buried oxide (BOX) layer of SIMOX samples was implanted with 20–30 keV D+ ion implantation at doses from 1014 to 10 16 cm −2 . Other samples were exposed to pure deuterium gas (0–1 MPa) at temperatures in the range 800–1100 K. Thermal des

Commercial wafers of silicon implanted with oxygen (SIMOX), with a 190 nm silicon top layer and 360 nm buried oxide layer, were analysed using positron beam spectroscopy. Depth profiles of defects have been obtained in the depth range from 0 to 2 μm

We have fabricated nanometer width Co/Si metal lines on Si(100) surfaces by ultrahigh-vacuum scanning tunneling microscopy (UHVSTM) based nanolithography on the hydrogen-passivated surface, combined with vapor deposition of Co at room temperature and

In this paper we discuss the potential of positrons for the study of defects in the MOS system. It is shown that Doppler broadening measurements of the positron annihilation radiation reveals properties not detected by conventional techniques such as

Doppler-broadening measurements can be improved by using a second Ge-detector for the coincidence detection of the second annihilation photon. The coincidence condition in combination with an energy relation results in a reduction of the background b

This paper describes a study of the effect of an external electric field on the behavior of positrons in metal-oxide-silicon (MOS) systems. Doppler broadening measurements of the annihilation radiation were performed on capacitors with identical ther

An improved approach is presented for the analysis of positron beam Doppler broadening data. Instead of analyzing the energy‐dependent shape parameter, the so‐called S(E) data, we combined the shape S(E) and wing W(E) data by plotting them as a t

We describe a study of the generation of slow interface states (time constants ≳40 s) by vacuum ultraviolet irradiation (Kr lamp, hν=10 eV) on metal–oxide–silicon samples with approximately 30 nm of thermally grown SiO2 and a transparent alumi
