It contains approximately 90 of tin oxide iv sno2 and 10 of indium oxide iii in2o3.
Ito glass sheet resistance.
Sheet resistance also known as surface resistance or surface resistivity is a common electrical property used to characterise thin films of conducting and semiconducting materials.
The standard is suitable for larger non contact probes four point probes.
It is a measure of the lateral resistance through a thin square of material i e.
Corning ultra thin glass.
It is commonly used to characterize materials made by semiconductor doping metal deposition resistive paste printing and glass coating examples of these processes are.

An ito glass has a property of low sheet resistance and high transmittance.
It is mostly used in research and development.
The ito glass is a thin transparent film similar to common glass but unlike glass it is a conductor of electricity because it is a kind of transparent conductive oxide tco.

The resistance between opposite sides of a square.
Ito glass is formed of tin oxide doped with indium.
Indium tin oxide ito is a ternary composition of indium tin and oxygen in varying proportions.
Doped semiconductor regions e g silicon or polysilicon and the resistors that are screen.
The ito sheet resistance standard consists of a glass substrate with a thin film of indium tin oxide sputtered on it.
Depending on the oxygen content it can either be described as a ceramic or alloy indium tin oxide is typically encountered as an oxygen saturated composition with a formulation of 74 in 18 o 2 and 8 sn by weight oxygen saturated compositions are so typical that unsaturated compositions are.
The entire surface of the glass substrate is coated with the ito film but only the center portion of the substrate 30 mm in diameter is certified.
