The problem of using diamond as a dielectric in the devices of microcircuits is an insufficient resolution of optical devices for controlling the light refraction coefficient, respectively, the dielectric permeability . In the work a fragment of a c-C monocrystal sample (a diamond variety) has been investigated. The dielectric permeability has been determined at the level of a spatial cell, which is presented in the hexagon anamorphous. This is a hexagonal prism with the base planes in the form of hexagons, in the center and in the angles of which the carbon atoms are arranged. The value  has been determined by the interaction of charges of central atoms in the base planes of the prism and bond electrons. This value has been calculated with accuracy up to the 7-th symbol after decimal point and can be used for practical purposes.

The practical application of the elliptical orbital model for calculation of the potential distribution between adjacent atoms will permit to determine the energy of the particles moving to the surface from space while depositing c -C films. The visualization of c -C cell in hexagonal amorphous has been presented. The visualization has revealed the tetrahedrons as well as the orbitals location and form. The orbitals look as flat, convex, closed curves, which envelope each pair of adjacent atoms. The parameters of these curves have been determined. The calculated values of orbitals parameters of c -C tetrahedrons are consistent with the ellipse mathematical definition. The process of producing diamond films depends on the state of the gas phase particles and on the deposition surface topology, as well as on position and the form of orbitals in cubic carbon crystal tetrahedron.

Cubic carbon c -C (diamond variety) is promising for use as a dielectric. The obstructing factors in the c -C application in microelectronics are the extreme conditions of its formation - pressure and high temperature, which are inadmissibly far from those applied in production. During the c -C synthesis the external pressure applied to raw material, and essentially bringing closer the carbon atoms and the transformation of their electronic cells, occur before the moment of formation of molecular bonds. The parameters of this transformation structure are fixed in a crystal grid as a reflection of the outwardly compression force and electric (pushing apart) force - of electrons located on orbitals of atoms. In the paper the construction of the c -C space cell (hexagonal prism) with elliptic orbitals of the bond of carbon atoms has been presented, the interaction of charges - the participants of the orbital formation - has been described. One of bonds for the purpose of assessment of the pressure value, necessary for bringing closer the reacting atoms in formation of this bond has been calculated. It has been shown that at the moment of bringing closer the carbon atoms, at which the balance of electric forces (these forces push apartt atoms) and compression forces and, also, of the outwardly force, the bond formation is possible.

The structure of the crystals of the (B, Al, Ga, In, Tl) metals nitrides has been presented by the closed-up tetrahedrons so that the «nitrogen» tetrahedron includes the apex of the «metal» one, and the «metal» one that one of the «nitrogen» tetrahedron. The parameters of the wurtzite and cubic syngony - the position and the distance between atoms, the nitrogen radius, the displacement of different atoms from the center of the tetrahedron masses, etc. - have been determined.

The specific features of the diamond structure and its interaction with the gas phase carbon atoms have been considered. The cause of the sequence of the c-C crystal three-layer structure has been revealed. It has been shown that the process of forming the layers of the carbon cubic crystal is spontaneous.

The active state of carbon atoms is achieved in plasma at rigid energetic conditions. Proportion of particles with enough energy to activate carbon atoms is small. This work considers the result of energy input to carbon atom, which was in inert state. It was shown that subsequent excitement and recombination activated carbon atoms. Active atoms formed covalent bonds with other atoms in crystal diamond. The states of carbon atoms and its subsequent transitions to the active state were revealed. The calculations have found that carbon atoms activization energy value is equal to 17,581079 eV.

Based on assumption of the energetic balance of the interaction between reagents (CH and O) and products (CO, HO) the energy of the bond between the carbon atoms in ethane - of the model of the carbon atoms state in the cubic carbon crystal - has been determined. It is in accordance with the excitation quintet state of carbon atoms.

Energy spectrum of gas particles in plasma is broad, ranging from fractions to 10s of electron volts. Proportion of particles with required energetic parameters, participating in cubic carbon c -C synthesis, is small. External energy deposition can transfer an inert carbon atom to active state and change its electronic configuration. Binding energy of c -C atom depends on energy sources interaction. In this work, the calculations found the binding energy value that was compared with value of energy of the bond between the carbon atoms in ethane. The advisability of external source, activated carbon atoms generator, is marked. It has been established that by adding accelerated carbon atoms with energy of 9,687 eV into reactor it is possible to increase productivity of films, coatings and bulk crystals growth.
