The STMicroelectronics group totals close to 50,000 employees, 16 advanced research and development units, 39 design and application centers, 16 main manufacturing sites and 78 sales offices in 36 countries.
The STMicroelectronics group was formed in June 1987 as a result of the merger between SGS Microelettronica of Italy and Thomson Semiconducteurs of France. In May 1998, the company changed its name from SGS-THOMSON Microelectronics to STMicroelectronics.
The primary focus of the STâ€™s Post Silicon Technology group is the scouting for new generations of Non-volatile Memories where the storage element is made of organic materials and non-conventional polymers.
Beyond the evolving technology aimed at pushing conventional CMOS logic and memories to the nanometric scale following Mooreâ€™s law, the Company is investing in more advanced research, to prepare for post-CMOS and post-silicon technology. The most important research issues in this area are:
- Molecular Electronics, which integrates functional organic molecules into solid state devices, as computational/non-volatile storage units, through a low-cost and silicon compatible technology for the 32nm node and beyond.
- Innovative materials, with chemical-physical and optical properties suitable to the development of Non-volatile Memories and other electronic applications. STâ€™s efforts go from the synthesis and characterization of materials to the fabrication of device prototypes using low cost deposition techniques.
- Polymer and hybrid electronics applications, focusing on the integration of innovative materials with low-cost processing techniques to develop novel device concepts. The team is in charge of transferring prototypes into real product demonstrators facing up to scaling and optimization aspects.
- Carbon Nanotube (CNT) elements, to be incorporated into industrial electronic (semiconductor) practice. Special attention is paid to the elaboration of low cost and reliable methods of CNT growth on chip and to the application of CNT as active nano-elements to operate with charge and spin of single electrons. That could mean future Integrated Circuits improved in terms of reduction of energy consumption and increasing of speed and reliability. The research into the nano-dimensional world requires the development of new quantum mechanical and finite element methods in order to design and model CNT nano-devices.
- Multi-scale Technology Modeling, in which the variety of computational techniques are used to determine equilibrium structures, energy spectra, density of states and the effects induced by defects in molecular structures. Potential applications of developed techniques, that aim to reduce costs and time consuming of PST experimental activities, include Molecular Electronics, Organic Light Emitted Diodes and Carbon Nanotubes.
