What does TCBG mean in CONTACT
TCBG (Top Contact Bottom Gate) is a type of transistor architecture where the source and drain contacts are located at the top of the transistor, while the gate contact is located at the bottom. This design offers several advantages over traditional transistor architectures, including reduced parasitic capacitance, improved electrostatic control, and higher switching speeds.
TCBG meaning in Contact in Contact
TCBG mostly used in an acronym Contact in Category Contact that means Top Contact Bottom Gate
Shorthand: TCBG,
Full Form: Top Contact Bottom Gate
For more information of "Top Contact Bottom Gate", see the section below.
- TCBG stands for Top Contact Bottom Gate. It is a type of thin-film transistor (TFT) technology used in the production of liquid crystal displays (LCDs).
- TFTs are semiconductor devices that control the flow of current in an LCD, allowing for the creation of images on the screen.
How TCBG Works
- In a TCBG TFT, the source and drain electrodes are located on the top surface of the semiconductor, while the gate electrode is located on the bottom surface.
- When a voltage is applied to the gate electrode, it creates an electric field that attracts or repels electrons in the semiconductor channel, controlling the flow of current between the source and drain electrodes.
Advantages of TCBG
