Indium Tin Oxide Coated Glass Slide

Indium Tin Oxide Coated Glass Slide Description

Indium tin oxide coated glass slide is one of the types of transparent conductive oxide (TCO) coated substrate. It is commonly known as ITO coated glass. The ITO coated glass has excellent conductive and high transmittance properties. The ITO glass is an N-type semiconductor. The uniform thin layer of Indium tin oxide 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 Celsius. 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.

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. 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 to 100 ohms per square. The transmittance of the ITO glass coverslips at 550nm is greater than 85%. The ITO film or layer thickness is in the range of 50nm to 200nm (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%.
