CBD system also is used as DIP coater to growth thin film or  the quantum dots and metal oxides and all-in solutions.

The CBD coater is a complete solution coating system.


FYTRONIX CBD  COATER includes

The system contains the following elements:
CBD controller 
Heating Plate
Temperature Controller
Magnetic Stirrer

CBD coater growth any film in a chemical bath on heating plate or magnetic stirrer. The bath temperature is automatically controlled by temperature controller from RT to 100 oC or more. 

CBD  COATER

The FYTRONIX CBD COATER is a tool to  growth thin film or quantum dots thin films. This CBD coater is widely used in ındustry and academia. The film thickness of the films is controlled by the Ph of solution or dipping cycle of the coater. The rate of withdrawal can be controlled with a  high degree of accuracy and reproducibility.
 
What is Chemical Bath Deposition (CBD)?
The technique of CBD involves the controlled precipitation from solution of a compound on a suitable substrate. The technique offers many advantages over the more established vapor phase synthetic routes to semiconductor materials, such as CVD, MBE and spray pyrolysis. Factors such as control of film thickness and deposition rate by varying the solution pH, temperature and reagent concentration are allied with the ability of CBD to coat large areas, in a reproducible and low cost process. In addition, the homogeneity and stoichiometry of the product are maintained partly by the solubility product (Ksp) of the material in question. A wide range of chalcogenide (e.g. CdS, ZnS and MnS) and chalcopyrite materials (e.g. CuInS2 and CuInSe2) have been prepared by CBD methods.
Typical CBD processes for sulfides employ an alkaline media containing the chalcogenide source, the metal ion and added base. A chelating agent is used to limit  the hydrolysis of the metal ion and impart some stability to the bath, which would otherwise undergo rapid hydrolysis and precipitation. The technique under these conditions relies on the slow release of S2- ions into an alkaline solution in which the free metal ion is buffered at a low concentration.
A major drawback of the CBD process is the inefficiency of the process, in terms of the utilisation of starting materials and their conversion to thin films. The extent of the heterogeneous reaction on the substrate surface is limited by two major factors, the competing homogeneous reaction in solution (which results in massive precipitation in solution) and deposition of material on the CBD reactor walls. We are developing continuous flow-recyclable CBD processes for the fabrication of CdS thin films for use as window materials in n-CdS:p-CdTe solar cells (see below). The large scale exploitation of these devices is partly dependent on a reduction of the potential environmental impact of the technology, as cadmium-containing compounds and wastes are highly regulated in the EU and elsewhere.
