Full Description of ITO Coated Glass

The Indium tin oxide coated glass is one of the types of transparent conductive oxide (TCO) coated substrates. It is commonly known as ITO coated glass. The ITO coated glass having excellent conductive and high transmittance properties. The ITO glass is an N-type semiconductor. The chemical formula of Indium tin oxide is Sn:In2O3. The uniform thin layer of Indium tin oxide (ITO) over a glass substrate makes it highly transparent and low surface resistance. The ITO coating over a glass sheet is carried out in the entirely vacuumed condition by magnetron sputtering method at around 300 degree C. It is a single side coating, where coated surface is conductive, and another surface is insulated. In this approach, there is passivation layer of silicon dioxide (SiO2) in between ITO layer and borosilicate glass surface. The standard thickness of SiO2 is 25 nm. The passivation layer is essential to increase the quality as well as longevity of ITO coated glass plate. The borosilicate glass or float glass is a single side finished substrate. The maximum operating temperature of ITO coated glass slide is 350 degree Celsius (i.e. 662 0Fahrenheit).

Customers can choose coating thickness based on coating resistivity required for the job. If you want we can assist via mail or suggest you refer coating thickness versus resistivity chart to ease the decision.

The ITO coated glass plate is laser cut majorly in square and rectangular shape, sometimes it customized in circular shape also. It is also called as ITO coated glass coverslip. The square shaped standard ITO coated glass slides size is 25mm, 50mm, 100mm, and 200mm. The rectangular shaped ITO glass slide is 50mm x 25mm and 75mm x 25mm. The maximum produced size of ITO coated glass substrate is 405mm x 305mm. The standard thickness of float glass which conventionally used for coating is 0.5mm, 0.7mm, and 1.1mm. The Indium Tin Oxide conductivity depends on the surface resistance, which is reciprocal to conductivity. The specified surface resistivity of the ITO coated glass sheet is in the range of 10 ohms/sq. to 100 ohms per square. The transmittance of the Indium Tin Oxide (ITO) glass coverslips at 550nm are greater than 85%. The ITO film or layer thickness is in the range of 50nm to 200nm (i.e. 500Å – 2000Å). The surface roughness is 1-10 nm depending on their specifications, whereas the ITO work function is 4.8~4.9eV after a proper cleaning. It is also known as ITO wafer. The haze of the conductive glasses is less than 1%.

We can also customized size and specifications of the product as per buyer requirement. The Indium Tin Oxide coated over a polished and unpolished float glass as well as OLED soda lime substrate. The ITO conductive film provides over a quartz and Corning glass substrate. In some instances, double side coated slide can also manufacture. It majorly used in the research laboratories, educational institutes, and industries. In research, it widely utilized for the fabrication of Dye-Sensitized solar cell or organic cells. It is also majorly used for Indium tin oxide touch screen. We also offer a cost effective solutions for many applications based on the bulk requirement. We also provide ITO patterning of the substrate as per ordered designs. The laser and wet etching use for the details patterning develop by Photolithography method. The direct soldering is not possible over an ITO thin film, hence there is a use of conductive paste, conductive ink or copper foil conductive adhesive tape. The ITO coated glass storage temperature is less than 20 degree centigrade for a better life and results.


We package ITO coverslips very carefully in a special protective packaging to ensure it reaches you clean and without slightest damage. However, there are clients who prefer to clean the glass once it arrives before putting it to use. For all such cleaning purposes, we recommend clearing it with high-quality lint-free cotton dipped in the solvent called the isopropyl alcohol. Clients are warned not to wipe coatings with alkali. Dilute sodium hydroxide solutions are commonly used for patterning ITO. If you use acid of any kind it will cause irreversible damage ITO coating on the glass surface.

We also have Premium order options where customers can place an order for anti-reflective or Index Matching Coatings to increase transmittance on the coating.

Cleaning And Handling of Product

While cleaning of ITO slides, safety apparel and protection should be wear. The cleaning process should be done in the fume hood to avoid contamination and maintain impurity free environment.
At the time of slides handling, the researcher should use powder free non-latex gloves, which should be handled carefully. While experimenting, if researched use substrate with bare hands, then chances of contamination of coated surface due to finger oil is very high. Therefore it advised using nylon or polyester gloves. Each slide is well packed in moisture free paper and placed is a way that, it should not rub each other.
During experimenting organic contaminant and dust particle present in the surrounding may adsorb on the surface of Indium tin oxide coating and hence cleaning of substrate become mandatory. Following is the cleaning method for ITO products.

Techinstro Advised to Use The Following Procedure For Ito Layer Cleaning.

  • Sonication of the sample plays an important role in the cleaning process of the substrate.
  • Initially, take acetone and mixed with the substrate, which is to be cleaned and sonicate approximately for 20 minutes.
  • Then take out of sample out of sonicator and make it dry.
  • Take Isopropyl alcohol (IAP) along with ITO plate for re-sonication for 20 minutes.
  • Now take out the sample and placed in UV-ozone instrument to remove the remaining organic contaminant. It also increases the hydroxyl concentration due to oxidation at surfaces.
  • Then placed the substrate in a vacuum oven to remove organic solvent used during the cleaning process.
  • After proper cleaning, placed the sample in a desiccator until its uses.

Lead Attachment (Electrode Formation) / Electrical Connections

To use the ITO coated glass plate as an electrode, it is necessary to attached leads to the conductive part of the ITO plate. There are various methods are available to make better electrical contact with conductive film and probes. The thickness of Indium tin oxide layer is mere hence it is important to attached probe at proper coating layer point. The contact between two is made by alligator clips in a way that the clips cut through coating or embed in it. It develops resistance between contacts and reduces current which is carried by conductive coatings. It also shows the drop in voltage.

In another method, the probes are attached with the help of highly conductive silver paste or bus compositions. In this case, the silver bus is applied on the ITO surfaces (i.e. on edges) and dried over there. The surface becomes highly conductive with the ITO transparent layer. Then attach the alligator pins in a way that it should penetrate silver bus and transparent conductor and make excellent contact in between. In this case, the silver bus material and ITO plate are both conductive; hence there is no high voltage and current drop.

An alternative method of electrode formation, the copper conductive tape is used for the connection of probe and Indium Tin oxide coated plate. The conductive copper tape which is having lower thickness is placed on a substrate and probe in a manner that it gets firmly attached to each other. This made development of mere resistance and current is passed without a drop. The observed voltage drop is low.

In one of the methods of attaching probe with conductive coatings with the help of silver bus composition or silver paste, but in this case, a fine wire of highly conductive metal such as copper, platinum, gold, silver etc. has been used. This method is known to be highly used method through out.

Electrical Characteristics Measurements

While selecting ITO coated glass plate( ITO Glass ), the resistivity is very important. The demand of resistivity is varied according to the application of end users. There are numbers of methods available to determined resistance.

As per the basic properties of electricity, resistance is a ration of the voltage applied between two electrodes attached to the surface of the thin conductive layer of the sample and current passes between them. In a case of ITO sample, the resistance is known as surface resistance “Rs”.

The resistivity of ITO glass sample is measured by multimeter or 4 probe tester.

By using a multimeter, there are following two ways to determine surface resistance.

1). The distance between two probes of multimeter should be 1 cm and placed the probe at an angle of 45 degrees to the surface so that you can get the exact resistivity of the substrate.
2). Cut ITO thin film in a square shape and coat the copper foil on upward and down side of the ITO film. Then place two probes on the copper foil and get reading for the sheet resistance.

The ITO coating is not uniform and isotropic due to its morphological variability. At the time of experiment, error or misplacing of electrodes orientation on the surface of ITO substrates also responsible for the resistance deviation. When alligator pins are attached to the substrate, there are chances of damaging thin film coating are higher. Hence it is advisable to touch surface lightly with the probe. This experiment also includes fringing effect, which is having some contact resistance.
