61Chemical vapor deposition — DC plasma (violet) enhances the growth of carbon nanotubes in this laboratory scale PECVD apparatus. Chemical vapor deposition (CVD) is a chemical process used to produce high purity, high performance solid materials. The process is often used in …
62Restricted randomization — Many processes have more than one source of variation in them. In order to reduce variation in processes, these multiple sources must be understood, and that often leads to the concept of nested or hierarchical data structures. For example, in… …
63Microelectromechanical systems — (MEMS) (also written as micro electro mechanical, MicroElectroMechanical or microelectronic and microelectromechanical systems) is the technology of very small mechanical devices driven by electricity; it merges at the nano scale into… …
64Copper indium gallium selenide solar cells — Copper indium gallium selenide (CuIn1 xGaxSe2 or CIGS) is a direct bandgap semiconductor useful for the manufacture of solar cells. Because the material strongly absorbs sunlight, a much thinner film is required than of other semiconductor… …
65Ultratech, Inc. — Ultratech, Inc. nasdaq|UTEK is a publicly traded international technology company based in San Jose, California which supplies equipment to global semiconductor fabs and foundries, and also makes industry leading tools for nanotechnology… …
66Vertical-cavity surface-emitting laser — The vertical cavity surface emitting laser (VCSEL; [v ɪxl] ) is a type of semiconductor laser diode with laser beam emission perpendicular from the top surface, contrary to conventional edge emitting semiconductor lasers (also in plane lasers)… …
67Nanoimprint lithography — is a method of fabricating nanometer scale patterns. It is a simple nanolithography process with low cost, high throughput and high resolution. It creates patterns by mechanical deformation of imprint resist and subsequent processes. The imprint… …
68Gravure (micro-fabrication) — La gravure (aussi appelée parfois par son nom anglophone, etching) est un procédé utilisée en micro fabrication, qui consiste à retirer une ou plusieurs couches de matériaux à la surface d un wafer. La gravure est une étape critique, extrêmement… …
69Stepper — A stepper is a device used in the manufacture of integrated circuits (ICs) that is similar in operation to a slide projector or a photographic enlarger. Steppers are an essential part of the complex process, called photolithography, that creates… …
70Polycrystalline silicon — Polycrystalline silicon, also called polysilicon, is a material consisting of small silicon crystals. It differs from single crystal silicon, used for electronics and solar cells, and from amorphous silicon, used for thin film devices and solar… …
