Physical and Predictive Models of Ultra Thin Oxide Reliability in CMOS Devices and Circuits

نویسنده

  • James H. Stathis
چکیده

The microelectronics industry owes its considerable success largely to the existence of the thermal oxide of silicon. However, recently there is concern that the reliability of ultra-thin dielectrics will limit further scaling to slightly thinner than 2nm. I will review the physics and statistics of dielectric wearout and breakdown in ultra thin SiO2-based gate dielectrics and discuss the implications of recent long term (>1 year) stress experiments on ultrathin SiO2 and oxynitride films.

Effect of Heavy Ion irradiation and Electrical Stress on Ultra-Thin Gate Oxide SOI MOSFETs

An accelerated wear-out of ultra-thin gate oxides used in contemporary deep-submicron CMOS technologies is one of the effects observed in MOSFETs submitted to irradiation with high LET particles [1-5]. The damage introduced in the gate oxide by an impinging ion may in fact act as a seed for further degradation produced by electrons and holes injected at high fields during a subsequent electrica...

A Novel Design of a Multi-layer 2:4 Decoder using Quantum- Dot Cellular Automata

The quantum-dot cellular automata (QCA) is considered as an alternative tocomplementary metal oxide semiconductor (CMOS) technology based on physicalphenomena like Coulomb interaction to overcome the physical limitations of thistechnology. The decoder is one of the important components in digital circuits, whichcan be used in more comprehensive circuits such as full adde...

Reliable CMOS VLSI Design Considering Gate Oxide Breakdown

As technology scales down into the nanometer region, the reliability mechanism caused by time dependent dielectric breakdown (TDDB) has become one of the major reliability concerns. TDDB can lead to performance degradation or logic failures in nanoscale CMOS devices, and can cause significant increase of leakage power in the standby mode. In this paper, the TDDB effects on the delay and power o...

Ultra-Thin, High Quality HfO2 on Strained-Ge MOS Capacitors with Low Leakage Current

Ultra-thin HfO2 MOS capacitors on strained-Ge (s-Ge) have been fabricated with an extracted effective oxide thickness (EOT) of 4.9 Å and leakage current less than 0.2 A/cm at |VG| < 0.5 V. The CV measurements show little hysteresis and areal capacitance scaling for 50×50 to 200×200 μm devices. A high series resistance is observed, likely due to a 500 meV valence band offset between the s-Ge and...

Ultra Thin Dielectrics for CMOS-Elements

The continued demand for higher density electronic circuits will meet several barriers with the next few years. One of the more obvious ones is the need for reliable method to grow ultra thin dielectric films, such as Al O , AlN, TiO , Si N and Si N . Doping of the oxide with nitrogen has been supposed to alleviative both, 2 3 2 3 4 x y the tunneling and boron transport issues. Here, we dissolv...
