A thin-film transistor (TFT) is a special type of field-effect transistor (FET) where the transistor is made by thin film deposition. TFTs are grown on a supporting (but non-conducting) substrate , such as glass .
Paul K. Weimer, also of RCA, implemented Wallmark's ideas and developed the thin-film transistor (TFT) in 1962, a type of MOSFET distinct from the standard bulk MOSFET. It was made with thin films of cadmium selenide and cadmium sulfide. The idea of a TFT-based liquid-crystal display (LCD) was conceived by Bernard Lechner of RCA Laboratories in
An oxide thin-film transistor (oxide TFT) or metal oxide thin film transistor is a type of thin film transistor where the semiconductor is a metal oxide compound. An oxide TFT is distinct from a metal oxide field effect transistor where the word "oxide" refers to the insulating gate dielectric (normally silicon dioxide). In an oxide TFT, the ...
The concept of a thin-film transistor (TFT) was first proposed by John Wallmark who in 1957 filed a patent for a thin film MOSFET in which germanium monoxide was used as a gate dielectric. Thin-film transistor was developed in 1962 by Paul K. Weimer who implemented Wallmark's ideas. [16] The TFT is a special type of MOSFET. [17]
It is currently used as the thin-film transistors for use in organic light-emitting diode (OLED) TV displays. IGZO-TFT and its applications are patented by JST. [4] They have been licensed to Samsung Electronics [4] (in 2011) and Sharp [5] (in 2012). In 2012, Sharp was the first to start production of LCD panels incorporating IGZO-TFT. [6]
More specifically, the use of polycrystalline silicon in thin-film transistors (LTPS-TFT) has high potential for large-scale production of electronic devices like flat panel LCD displays or image sensors. [1] LTPS is polycrystalline silicon that has been synthesized at ~650 °C and lower, compared to traditional methods (above 900 °C).

Like a TFT-LCD display, millions of roughly 0.2 mm pixels each containing a thin-film transistor form a grid patterned in amorphous silicon on the glass substrate. [1] Unlike an LCD, but similar to a digital camera's image sensor chip, each pixel also contains a photodiode which generates an electrical signal in proportion to the light produced ...
