      Ultrathin Hf-Ti-O higher k gate dielectric films (~ nm) have been prepared by atomic layer deposition. Their electrical properties and application in ETSOI (fully depleted extremely thin SOI) PMOSFETs were studied. It is found that at the Ti concentration of Ti/(Ti + Hf) ~%, low equivalent gate oxide thickness (EOT) of ~ nm and acceptable gate leakage current density of A/cm2 Cited by: 1. For these reasons, the highk gate dielectrics have been intensively investigated in order to possibly replace the conventional SiO2 in silicon technology. Since high-k dielectrics provide the same capacitance with a thicker film, the leakage current reduction, therefore, less the standby power consumption is one of the huge advantages. high-k materials, while maintaining the same value of the capacitance required metal-oxygen bonds are more or less for controlling the current flow in the channel, can resolve all the aforementioned problems.

Silicon dioxide (SiO 2) has been used as a gate oxide material for decades. As metal-oxide-semiconductor field-effect transistors (MOSFETs) have decreased in size, the thickness of the silicon dioxide gate dielectric has steadily decreased to increase the gate capacitance and thereby drive current, raising device performance.

As the thickness scales below 2 nm.

Material requirements for high-k gate dielectrics There is a set of material and electrical requirements for a viable alternate high-k gate dielectric material [1,12,13]. Major requirements include: Larger energy band gap with higher barrier height to Si substrate and metal gate to reduce the leakage current.

Large k. The Penryn processor debuted Intel’s 45nm fabrication, and was the first to utilize high-k gate dielectrics and metal gate electrodes. This change in technology was significant for a number of reasons: the processes used were far in advance of Intel’s competition; it provided a basis on which Intel could build and scale down still further.

However, continual gate dielectric scaling will require high-K, as SiO 2 will eventually un out of atoms for furtherr scaling.

Most of the high-K gate dielectrics investigated are Hf-based and Zr-based [ref.
