Any thin but rigid plate of solid material, esp. of discoidal shape; -- a term used commonly to refer to the thin slices of silicon used as starting material for the manufacture of integrated circuits.
thin (thickness depends on wafer diameter, but is typically less than 1 mm), circular slice of single-crystal semiconductor material cut from the ingot of single crystal semiconductor; used in manufacturing of semiconductor devices and integrated circuits; wafer diameter may range from 25 mm to 300 mm; learn more.
All semiconductor devices are fabricated on wafers. Round wafers are used in order to simplify automated handling during manufacturing. CCDs are typically fabricated on 4", 5", or 6" wafers. The semiconductor industry as a whole is currently moving toward 8" wafers, although one day wafers will be as large as an LP or record (12" in diameter)! The larger the wafer, the larger the number of devices that can fit on one wafer--thus reducing manufacturing costs.
A polished slice cut from a drawn cylinder of monocrystalline silicon, and the starting point in chip manufacture. A wafer is less than 1 mm thick and may have a diameter between 25 and 300 mm, depending on the material involved.
This refers to a flat round piece of silicon that is used in the manufacture of microprocessors. Fabrication plants, or fabs, typically will take a wafer and carve many several microprocessors into it. Over the years, wafer size is increasing, so that more chips can be fit on a single wafer. Wafers are created by taking a cylinder of silicon and slicing it - much like taking a loaf of bread, and cutting slices - but to much more precise measurements.
A disk of semiconductor material that forms the base on which a number of identical integrated circuits are built. In some cases, two or more designs may be built on the same wafer. In most facilities, five or more wafers are brought through each fabrication step simultaneously in a group known as a wafer lot.
A round flat disk most often made of silicon that is patterned with several die by semiconductor thin-films processing. Each wafer has a flat or notch cut into its edge to help with aligning or orienting the wafer.
A thin, right cylindrical section slice of a semiconductor ingot or boule, from which discrete semiconductors or integrated circuits are manufactured. For RF/microwave devices, a wafer is typically 4 - 6 inches or 100 - 200 mm in diameter, and from 0.005 to 0.030 inches thick.
a round disc of semiconductor material most commonly Silicon, although Gallium Arsenide and other semiconductor materials are also used. Wafers are a few millimeters thick and are available in a variety of diameters with 100 millimeter, 125 millimeter, 150 millimeter and 200 millimeter being the most common and 300 millimeter just entering use. Many Integrated Circuits are simultaneously fabricated on wafers during the wafer fabrication process.
When most semiconducting material is purified, it comes out in long sausages between 1 and 8 inches in diameter, which are then sliced into wafers, roughly 1 millimeter thick. The wafer is then used as the substrate for forming semiconductor devices.
Thin circular cutout from silicon crystal where a matrix and chips are etched. The most ubiquitous size is 200mm or 8 inchs. A technological transition is underway towards 300mm or 12 inchs. 300mm is used for the most advanced integrated circuits and those for which the line width is inferior to 110nm.
A flat, thin piece of semiconductor material used in the construction of a chip. A wafer goes through a series of photomasking and etching steps to produce the final chip,which has leads attached and ... more
In cooking, a wafer can refer to a crisp, sweet, very thin, flat, and dry cake that is often used to decorate ice cream. Wafers can also be made into cookies with cream flavoring sandwiched between them. They frequently have a waffle surface pattern.
Eating a wafer will restore lost stamina. Most wafers are snapped up soon after a reset, but there are some that are only useful to lower-level players, and these are normally lying around for some time. They're in the villa, the monastery and the formal gardens.
