Single wafer SPM systems use a high volume of chemistry which runs to drain, while meeting the cleaning specifications below 28nm.
The data collected shows this new system meet the specifications, whilst saving more than 80%of SPM chemistry.

Abstract.
Here researchers will discuss stannous complex of succinimide as lubricating oil additive and its lubricating chemistry.
Structure of the complex Infrared spectrum of the complex indicates that nitrogen in succinimide has linked with stannous ion in dihydro-stannous chloride by stable chemical linkage-coordination chemical bond.
The proposed structure of the complex is The Characteristics of the Stannous Complex as Lubricant Additive Dispersibility Dispersibilty of the complex can be evaluated by spot test.
All mentioned above endow the complex compound with the modified performances of lubricating chemistry as engine oil additives.

There is system are based on polymeric sensor materials (structures).
Quantum chemical calculations were carried out in the programs HyperChem, which allowed receiving a geometric image of the molecule, as well as «GAUSSIAN», which obtaine polymer structure (refer with: Fig. 1) and thermodynamic parameters of stabilized structures.
Fig. 1 -1)-Cyclic trimer structure of polypyrrole; 2)- Cyclic trimer structure of polyacrylonitrile An algorithm modeling of polymer materials in the software package Matlab has been developed and implemented for these systems.
To do this, quantum chemistry calculations were carried out for the structures of silver-PAN.
