The field effect transistor, FET is a key electronic component using within many areas of the electronics industry. The FET used in many circuits constructed from discrete electronic components in areas from RF technology to power control and electronic switching to general amplification. The 2.0 L (1,998 cc) fuel-injected, turbocharged FET version of the FE produced 135 hp (101 kW; 137 PS) at 5250 rpm and 175 lb⋅ft (237 N⋅m) at 2800 rpm. It was a variant of the 8-valve SOHC FE Featuring a small turbocharger and no intercooler producing 7 psi (0.48 bar) of boost. As such it features the same 86 mm (3.39 in) bore. We would like to show you a description here but the site won’t allow us.
One-Transistor FeFET memory
- FE Technologies has transformed the way our library clients work – creating efficient Library RFID circulation processes, and designing an outstanding user experience for the library’s own customers.
- A ferroelectric field-effect transistor (Fe FET) is a type of field-effect transistor that includes a ferroelectric material sandwiched between the gate electrode and source-drain conduction region of the device (the channel). Permanent electrical field polarisation in the ferroelectric causes.
Due to the fact that hafnium oxide represents the state-of-the-art gate insulator for literally all high-k metal-gate (HKMG) process nodes, the inherent advantage of ferroelectric HfO2 is immediately revealed: You can take a standard HKMG transistor, modify its gate insulator to become ferroelectric and end up with the industry’s first nonvolatile HKMG transistor, the FeFET (see Fig. 3).
Fefet Operation
The FeFET shows nonvolatile characteristics due to the fact that the two stable, remanent polarization states of the now ferroelectric gate insulator modify the threshold voltage even when supply voltage is removed. Accordingly, the binary states are encoded in the threshold voltage of the transistor (see Fig. 4). Even though similar to Flash in its operation, the FeFET provides orders of magnitude improvement in almost any performance attribute (see also “Major differentiation to competition”). The FeFET for HKMG is introduced in order to become what Flash is today for Poly / SiON technology nodes: The overall leader in nonvolatile memories.

Fig. 4: Illustration of FeFET (n-type) functionality. When the ferroelectric polarization is pointing downwards (left) electrons invert the channel region permanently bringing the FeFET into the 'ON'-state. If the polarization is pointing upwards (middle), permanent accumulation is created and the FeFET is in the 'OFF'-state. Accordingly, binary states are encoded in the threshold voltage of the transistor (right).
