silicon
The dominant semiconducting material used in integrated circuits at this time (2001)
An element which is the primary component of computer chips Related terms: Chip
Silicon, atomic number 14 on the periodic table, is a semiconducting material from which integrated circuits (computer chips of all types--processors, memory chips, etc ; CCDs; transistors; etc ) are created Silicon is not found in its pure raw form in nature, but mostly in combination with other elements, as in sand and quartz A type of sand called quartzite is purified to create silicon for use by the semiconductor industry
A tetravalent, nonmetallic element used to fabricate CCDs
(SI) - A nonmetallic chemical element, number 14, which is a major component of many types of rocks and minerals on Earth; used to make glass, concrete, and semiconductors solar core - The central region of the sun's structure that consists of protons, neutrons, nuclei, and free electrons and is the site of proton-proton fusion reactions solar nebula - A diffuse mass of interstellar dust and/or gas that is thought to be the remnants of the material out of which the sun formed
A nonmetalic element analogous to carbon
Its oxide is silica, or common quartz, and in this form, or as silicates, it is, next to oxygen, the most abundant element of the earth's crust
a tetravalent nonmetallic element; next to oxygen it is the most abundant element in the earth's crust; occurs in clay and feldspar and granite and quartz and sand; used as a semiconductor in transistors
Second only to oxygen in abundance in Earth's crust, it never occurs free but is found in almost all rocks and in sand, clay, and soils, combined with oxygen as silica (silicon dioxide, SiO2) or with oxygen and metals as silicate minerals. It occurs in many plants and some animals. Pure silicon is a hard, dark gray solid with a metallic lustre and the same crystal structure as diamond. It is an extremely important semiconductor; doped (see dopant) with boron, phosphorus, or arsenic, it is used in various electronic circuit and switching devices, including computer chips, transistors, and diodes. Silicon is also used in metallurgy as a reducing (see reduction) agent and in steel, brass, and bronze. Its usual valence in compounds is
A solid element (number 14 on the periodic table) that is abundantly available in the form of SiO2 Its extreme abundance, moderate processing temperatures, and the stability of its native oxide make it the preferred semiconductor material
Do not confuse silicon with silicone
Atomic weight 28
A non-essential mineral Tissues such as arteries, tendons, skin, connective tissue, cornea and sclera (white of the eye) contain relatively large amounts of silicon Collagen, the protein glue that holds us together, contains silicon in silanolate form While vitamin C functions only as a catalyst in the formation of collagen, silicon is actually a structural part of collagen Silicon containing substances are found in all cartilage and in the material binding cells together Silicon may be needed for proper bone structure and growth
A tetravalent nonmetallic element (atomic number 14, atomic weight 32, chemical symbol Si) that occurs as the most abundant element next to oxygen in the earth’s crust
A brownish crystalline semimetal used to make the majority of semiconductor wafers
Called also silicium
Chemical symbol Si A non-metallic element, essential in the smelting of numerous ferrous and non-ferrous metals SILICON-BRONZE-An alloy of copper and 1 5-3% silicon with various third elements (zinc, tin, or manganese)
A brittle, grey, crystalline chemical element which, in its pure state, serves as a semiconductor substrate in microelectronics It is naturally found in compounds such as silicon dioxide
Silica is used in the form of sand and clay for many purposes; as quartz, it may be heated to form special glasses. Silicates are used in making glass, enamels, and ceramics; sodium silicates (water glass) are used in soaps, wood treatment, cements, and dyeing. See also silane; silicone
An element used in making the ceramic wafers out of which computer chips are punched
