"Nanospin Electrons " Multilayer Spatterning

Note: In nanoelectronics and  "nano spin electrons" technology  , special parameters and systems must be used to perform such processes. For example, in the metal marking process,  it is inevitable to use copper metal instead of the common aluminum metal for internal connections between different practical parts. However, the rapid penetration of  Cu atoms under Si during heat treatment leads to the formation of a copper silicide layer and ultimately causes the destruction of the electronic component.

To solve this  problem, usually in  "Nano Spin Electrons"  they use an intermediate layer of retarding materials such as Ta, w or Mo as a penetration barrier to improve the thermal stability of the Si/Cu layer  . In the characterization of  "nano spin electrons"  and Si/Ta/Cu multi-layer systems, there is an effect of negative bias voltage on improving the electrical and structural properties of the penetration barrier of the Ta sputtering layer in the Si/Ta system. Surface processes of the Si layer, including burning, are carried out by plasma and ion beam technology. This kind of  integrated circuits with their unique characteristics in the nanometer scale have various applications of mesoscopic systems.

Modeling  of Si/Cu nanospin electrons  based on a relationship between molecular mechanics and solid mechanics, an energy-equivalent model is used for the mechanical properties and nanomolecular structure of the sputtering layer of materials.  Macroscopic properties of  "nano spin electrons"  Like melting point, boiling point and electrical conductivity, it is done through a sample that is large enough to be measured under normal laboratory conditions. When the melting point of a nanomolecule is measured, in fact, the behavior of a  large number of nanoparticle molecules is examined, and this is not true for all materials; When the material size is reduced and reaches nanometer dimensions, completely different behavior and properties may be seen compared to the same material in large dimensions. Properties of   "Nanospin Electrons" It can depend on its size. This fact can be contradicted by the well-known fact that the properties of substances (solid, liquid and gas) are only related to the atoms and molecules that make up the substance and their bonding type or to the arrangement of the atoms. This is in the macro and micro dimensions. It is true, but everything is modified in nano dimensions, as a result of which the material properties may undergo fundamental changes.

Conclusion:

In nanoelectronics and  "nano spin electrons"  technology , special parameters and systems must be used to perform such processes. For example, in the metal marking process,  it is inevitable to use copper metal instead of the common aluminum metal for internal connections between different practical parts. However, the rapid penetration of  Cu atoms under Si during heat treatment leads to the formation of a copper silicide layer and ultimately causes the destruction of the electronic component.
