Si recess structure formed by plasma-induced physical damage and its effects on the device performance were studied. The depth of Si recess region (dR) was determined from the experiments by using an inductively coupled plasma reactor with simple Ar gas mixtures. Threshold voltage shift (DeltaVth) of n-ch MOSFETs with the recess structure was modeled by using device simulation for various dR. The...
Polarities of plasma charging damage in n- and p-channel MOSFETs with Hf-based high-k gate stack (HfAlOx/SiO2) were studied for two different plasma sources (Ar-and Cl-based gas mixtures), and found to depend on plasma conditions, in contrast to those with conventional SiO2. For Ar-plasma, which was confirmed to induce a larger charging damage, both n- and p-ch MOSFETs with high-k gate stacks suffer...
Novel 3D stacked gate-all-around multichannel CMOS architectures were developed to propose low leakage solutions and new design opportunities for sub-32 nm nodes. Those architectures offer specific advantages compared to other planar or non planar CMOS devices. In particular, ultra-low IOFF (< 20 pA/mum) and high ION (> 2.2 mA/mum) were demonstrated. Moreover, those transistors do not suffer...
We have observed new charge trapping phenomena in sub-80-nm DRAM recessed- channel-array-transistor (RCAT) after Fowler-Nordheim (FN) stress. Gate stack process strongly affected the charge trapping and the trap generating in oxide bulk and interface of RCAT. According to the trapped charges and/or the generated traps after FN stress, the data retention time and writing capabilities of DRAM were dramatically...
