EM Microelectronic Produces the World's First IC Operating Lower Than 0.5V Using Fully Depleted SOI Technology.Business Editors/High-Tech Writers MARIN, Switzerland--(BUSINESS WIRE)--Oct. 28, 2002 EM Microelectronic announced today that it is ready to start producing a high-performance, ultra-low-voltage and ultra-low-power integrated circuit integrated circuit (IC), electronic circuit built on a semiconductor substrate, usually one of single-crystal silicon. The circuit, often called a chip, is packaged in a hermetically sealed case or a nonhermetic plastic capsule, with leads extending from it for using fully depleted de·plete tr.v. de·plet·ed, de·plet·ing, de·pletes To decrease the fullness of; use up or empty out. [Latin d silicon-on-insulator (FD SOI (Silicon On Insulator) A chip architecture that increases transistor switching speed by reducing capacitance (build-up of electrical charges in the transistor's elements), and thus reducing the discharge time. The power requirement is also reduced in some designs. ). This is believed to be the first IC in FD SOI operating at a guaranteed voltage lower than 0.5V over the whole voltage and temperature range. This breakthrough has been permitted by EM Microelectronic's unique expertise acquired over 25 years in designing and producing ultra-low-power and ultra-low-voltage integrated circuits Integrated circuits Miniature electronic circuits produced within and upon a single semiconductor crystal, usually silicon. Integrated circuits range in complexity from simple logic circuits and amplifiers, about 1/20 in. (1. for the microelectronic industry. "The chip being produced is a sophisticated circuit to be used in the watch industry, containing more than 50% of analog cells. The analog portion of the circuit is operating at 0.5V, while the digital part works even down to 0.35V," said Mougahed Darwish, president of the management board of EM Microelectronic. "We are also developing a voltage reset IC with an astonishingly a·ston·ish tr.v. as·ton·ished, as·ton·ish·ing, as·ton·ish·es To fill with sudden wonder or amazement. See Synonyms at surprise. low reset threshold voltage The threshold voltage of a MOSFET is usually defined as the gate voltage where a depletion region forms in the substrate (body) of the transistor. In an NMOS the substrate of the transistor is composed of p-type silicon which has more positively charged electron holes compared to of 0.7V. This IC will be of ideal use with the coming generation of sub-1V microcontrollers, and is perfect in portable applications, which are becoming increasingly complex." Besides the well-known high-frequency applications that most semiconductor manufacturers are focusing on today using partially depleted (PD) SOI technologies, EM Microelectronic is developing its own 0.5um FD SOI process with properties including ultra-low threshold voltage down to 0.4V and high temperature operation up to 225 degrees C. As such, EM is the only European semiconductor manufacturer to produce FD SOI in 0.5um technology. The properties of this process include dual gates, 3 metal layers, silicide sil·i·cide n. A compound of silicon with another element or radical. Noun 1. silicide - any of various compounds of silicon with a more electropositive element or radical and elevated source and drain. Highly accurate and stable manufacturing capabilities allow EM to reach a very thin silicon film thickness of 40nm. Commercial use for the FD SOI technology is targeted at applications requiring either ultra-low-voltage operation or high performance at extremely high temperature. It is ideal for handheld and battery-powered applications. It also includes automotive engine control, field-powered RF tag used in very hot environments, automotive immobilization Immobilization Definition Immobilization refers to the process of holding a joint or bone in place with a splint, cast, or brace. This is done to prevent an injured area from moving while it heals. , smart card IC, well logging equipment and analog front-end for pressure, temperature, magnetic and optical sensors. FD SOI also has a bright future for use on system-on-chip since high component integration and low-power requirements drive the use for ultra-low voltage technologies. EM pursues an active development by integrating EEPROM (Electrically Erasable Programmable ROM) A rewritable memory chip that holds its content without power. Although EEPROMs spawned flash memory, EEPROMs are byte addressable at the write level, whereas flash chips must erase a block of bytes before rewriting. memory cells to its process. As a leader and pioneer in this market, EM plans to offer foundry services at its headquarters for FD SOI to customers interested in using this advanced technology.

MOS (1) (Metal Oxide Semiconductor) See MOSFET. (2) (Mean Opinion Score) The quality of a digitized voice line. It is a subjective measurement that is derived entirely by people listening to the calls and scoring the results from transistors built in SOI technology show superior performance in low-voltage operation. Partially depleted means that the top silicon is thick enough (100-200nm) for the depletion width not to reach the buried oxide so that a neutral region exists below the channel and depletion region. Partially depleted SOI best suits applications requiring a higher operation frequency. Fully depleted means that the top silicon is thinner (50nm or less) than the depletion width beneath the channel and the depletion region extends to the buried oxide. SOI realizes both ultra-low voltage and high-temperature operations.
