Introduction

A method for determining the integral density of structural defects nD
in SiO2+Si disk – wafer plates was developed, which is the basis of metal – dielectric – semiconductor (MDS) structures in the manufacture of large integrated circuits (LIC) for production technology to express the post-operational control of the perfection of the structure of multilayer epitaxial structures and the growth reliability of decent p-n junctions in the production of semiconductor devices [1-3]. Amplitude-dependent IF measurement (ADIF) can be used as a highly sensitive method to monitor the nanoplastic deformation eND
of SiO2+Si wafer plates [4-6].

Experimental procedure

The study of the influence of structural defects on the damping of vibrations of SiO2+Si wafer plates with diameter D ≈ 100 mm and thicknesses of hSiO2
≈ 600 nm allows the estimation of the degree of perfection of the crystalline structure. Ultrasonic (US) pulse-phase method using USMV-LETI, modernized USMV-KNU and computerized “KERN-4” devices with frequencies f┴

≈ 0.7 MHz and f║

≈ 1 MHz and were used [7-10].

Results and discussion

The temperature dependence of IF Q-1(T) in SiO2+Si wafer plates p-type, doped with B, KDB-7.5(100) with diameter D ≈ 100∙10-3 m, SiO2 layer thickness hSiO2
≈ 100 nm, and Si layer thickness hSi
≈ 460∙103 nm are shown. IF Q-1

Conclusions

The study of SiO2+Si wafer-plate vibrations at adjacent harmonic frequencies f0
and f2
made it possible to develop a technique for determining the structural defect density nD
and the broken layer depth hBL
.

Internal friction Q-1
, dynamical shear modulus G, dynamical elastic modulus Е, Poisson coefficient μ are dependent from SiO2+Si wafer-plate anisotropy.

The increase of the nanocomposite crystallinity degree at growth of multiwalled carbon nanotubes concentration filling with the nanotubes of matrix results in the decline of content of organized phase.

As the result of mechanical study the presence of the strong effect between polyamide, polyvinylchloride, polyethylene and multiwalled carbon nanotubes was confirmed. The presence of the strong interaction for nanocomposite between polyamide-6 (NH(CH2)5CO)n and multiwalled carbon nanotubes was confirmed by mechanical studies.
