It's possible that you have an electronic device that usesFinFET technology and you don't
The word FinFET has become an abbreviation for "field-effect transistorFin", which in Spanish meansFin field effect transistor (fin): This is a transistor that is built on a silicone insulator substrate.The FinFET transistor consists of a source, a drain contact, and a gate to control the flow of current.
Imec recently introduced the smallestsilicon FinFET, which functions as a biosensor. The developers managed to create an ultra-small transistor: the fin width is 13 nm, and the gate length is 50 nm.
Thanks to the high degree of integration and lowcost field-effect transistors (FETs) have attracted great interest for work in the field of biosensing - detection of DNA, proteins, viruses and pH determination. When biomolecules bind to the chemically modified dielectric surface of the gate, its threshold voltage changes, resulting in a measurable signal.
Despite the continuous progress of research inIn this area, biosensitive transistors - BioFET devices - have not yet shown their full potential in the market. Imec investigated how an advanced generation of CMOS FETs (short-gate finFETs) can improve the sensitivity of BioFETs. This will help to use it in applied medicine. Such finFETs offer advantages in terms of high integration and parallelism, but very little is known about their potential as BioFETs.
Imec looks forward to mass production and integration of its transistor devices, where tens of thousands of BioFETs operate in parallel.
With its bio finFET devices up to 50 longnanometers imec demonstrated a reliable signal for DNA hybridization and detection of tens of DNA molecules on a nanometer-sized FinFET surface. Based on experiments and simulations, imec predicts that single-molecule detection with signal-to-noise ratio (SNR)> 5 will be possible with FinFET transistors with a wavelength of less than 70 nm.

Electronic component from semiconductormaterial, usually with three terminals, capable of driving a significant current in the output circuit from a small input signal, which makes it possible to use it for amplification, generation, switching and conversion of electrical signals. Currently, the transistor is the basis of the circuitry of the vast majority of electronic devices and integrated circuits.
A nanometer is a fractional unit of length in the International System of Units, equal to one billionth of a meter.
