Opis:
The characteristic dome-like shape distribution of electric parameters (with the biggest values in the middle and the lowest values in the corners of the gate) has been observed in our investigations. Taking the results of the papers into account, the following hypothesis was drawn: the shape distribution of electrical parameters has been caused by the irregular shape of stress distribution under the metal gate. To prove or deny the assumed hypothesis, a lot of investigations on stress and strain in MOS structures are being performed. The study of the atomic composition of electronic components constitutes the starting point of their characterization. Therefore, in this paper, we present experimental results of hydrogen, oxygen, aluminum, silicon, and copper concentrations in MOS structures carried out by the Rutherford backscattering spectrometry and elastic recoil detection methods. These techniques allow inter alia determination of silicon and oxygen content as a function of the position x on a wafer. On the basis of depth profile elastic recoil detection measurements performed on Al and AlSiCu gates, a much larger hydrogen content in the surface layer for MOS structure with Al gate was confirmed. Copper atoms were detected only in the AlSiCu gate.

Opis:
The semi-isolating GaAs (100) samples irradiated with fluence 3 × $10^{15}$ ions/$cm^{2}$ of $In^{+}$ ions were characterized by using the methods: Rutherford backscattering spectroscopy, nuclear reaction analysis and ellipsometric spectroscopy. The values of the thicknesses layers enriched with oxygen and the implanted were determined by the methods of nuclear reaction analysis and Rutherford backscattering spectroscopy. Multilayer models were applied for determination of the optical constants (refraction and extinctions coefficients) of investigated samples. The thickness of native oxide covering the surface of implanted GaAs and refraction coefficients were increased after implantation with indium. The spectrum of extinction indexes as a function of light wavelength has two bands near the light wavelengths 400 nm and 480 nm. The observed effects can be interpreted as formation of local oxides of In and InAs precipitates or ternary alloys in enriched with oxygen layers at the surfaces of implanted GaAs.

Opis:
Semi-insulating GaAs wafers have been implanted with 250 keV In^{+} ions at a fluence of $3 \times 10^{16} cm^{-2}$. The samples prepared in this way were subsequently annealed at a temperature of 600°C or 800°C for 2 h. Thicknesses of the native oxide layers on implanted GaAs after samples storage in air were evaluated using the Rutherford backscattering spectrometry with the nuclear reaction $O^{16}(α,α)O^{16}$ method. The chemical composition of native oxide layers on $In^{+}$ implanted and annealed GaAs has been studied using X-ray photoelectron spectroscopy. $As_{2}O_{3}$, $As_{2}O_{5}$, $Ga_{2}O_{3}$, $GaAs$, $InAs$ and $InAsO_4$ compounds were detected in these layers.

Opis:
Depth distribution of implanted species and microstructure of oxygen-containing Czochralski grown silicon (Cz-Si) implanted with light ions (such as $H^{+}$) are strongly influenced by hydrostatic pressure applied during the post-implantation treatment. Composition and structure of Si:H prepared by implantation of Cz-Si with $H_{2}^{+}$; fluence D = 1.7 × $10^{17} cm^{-2}$, energy E = 50 keV (projected range of $H_{2}^{+}$, $R_{p}(H)$ = 275 nm), processed at up to 923 K under Ar pressure up to 1.2 GPa for up to 10 h, were investigated by elastic recoil detection Rutherford backscattering methods and the depths distributions of implanted hydrogen and also carbon, oxygen and silicon in the near surface were determined for all samples. The defect structure of Si:H was also investigated by synchrotron diffraction topography at HASYLAB (Germany). High sensitivity to strain associated with small inclusions and dislocation loops was provided by monochromatic (λ = 0.1115 nm) beam topography. High resolution X-ray diffraction was also used.

Opis:
The paper presents slow positron beam studies of the stainless steel grade 304 AISI samples annealed in the flow $N_2$ atmosphere and sandblasted under different pressure from 1 to 7 bar. Heating of specimens caused formation of an additional layer on the surface which can be identified as oxides. Sandblasting reduces the thickness of the oxide layer and also defects concentration (vacancies as we suppose) decreases in dependence on pressure applied during blasting. Additionally, the atomic concentrations of oxygen have been obtained using nuclear methods (Rutherford backscattering and nuclear reactions) in the near surface layers of the studied samples.
