What is the gate oxide thickness?

Gate oxide is formed by thermal oxidation of the silicon of the channel to form a thin (5 – 200 nm) insulating layer of silicon dioxide.

Gate oxide is formed by thermal oxidation of the silicon of the channel to form a thin (5 – 200 nm) insulating layer of silicon dioxide.

What is the effect of radiation environment in an oxide?

Ionizing radiation can induce significant charge buildup in these oxides and insulators leading to device degradation and failure.

How does radiation affect concrete?

During its lifetime, concrete will change properties naturally due to its normal aging process, however nuclear exposure will lead to a loss of mechanical properties due to swelling of the concrete aggregates, and thus damaging the bulk material.

What causes radiation damage?

Radiation is the energy released from atoms as either a wave or a tiny particle of matter. Radiation sickness is caused by exposure to a high dose of radiation, such as a high dose of radiation received during an industrial accident.

What are thin and thick oxides?

Thin oxide transistors are used wherever possible to achieve small area and low power consumption and thick gate oxide transistors are used to ensure low leakage current and to achieve higher voltage swing.

Why is the gate oxide thickness of MOS devices being reduced?

The gate oxide thickness of metal-oxide-semiconductor (MOS) devices is being reduced step by step to match the reductions in integrated circuit scale [1 ]. The minimum gate oxide thickness is limited by the maximum allowable leakage current and device reliability.

What is gate leakage in nano CMOS?

Gate Leakage in Nano-CMOS Both ON and OFF states contribute to gate oxide leakage. Transient effect is significant and can be captured via effective tunneling capacitance. ION and IOFF metrics to quantify gate leakage current during steady state.

Does gate oxide have to have a low atomic diffusion coefficient?

A gate oxide must withstand processing to temperatures of ∼1000 °C without changing its state. It must also not mix with either the Si channel or the poly-Si or metal-gate electrode, or allow components of the gate electrode to diffuse through it. All these aspects require the gate oxide to have low atomic diffusion coefficients.

Does electron injection induce oxide degradation in thin gate oxide?

As a result, the stored charges generate the dielectric breakdown of thin gate oxide [ 1, 3, 5–9 ]. Electron injection induced hole trapping near the gate-oxide interface was suggested as a possible mechanism for oxide degradation [ 5, 10, 11 ].
