Public Company
A public company is a company whose ownership is organized via shares of share capital, stock which are intended to be freely traded on a stock exchange or in over-the-counter (finance), over-the-counter markets. A public (publicly traded) company can be listed on a stock exchange (listing (finance), listed company), which facilitates the trade of shares, or not (unlisted public company). In some jurisdictions, public companies over a certain size must be listed on an exchange. In most cases, public companies are ''private'' enterprises in the ''private'' sector, and "public" emphasizes their reporting and trading on the public markets. Public companies are formed within the legal systems of particular states and so have associations and formal designations, which are distinct and separate in the polity in which they reside. In the United States, for example, a public company is usually a type of corporation, though a corporation need not be a public company. In the United Kin ...

Probe Card
A probe card (commonly referred to as a DUT board) is used in automated integrated circuit testing. It is an interface between an electronic test system and a semiconductor Wafer (electronics), wafer. Use and manufacture A probe card or DUT board is a printed circuit board, printed circuit board (PCB), and is the interface between the integrated circuit and a test head, which in turn attaches to automatic test equipment, automatic test equipment (ATE) (or "tester"). Typically, the probe card is mechanically docked to a Wafer testing prober and electrically connected to the ATE . Its purpose is to provide an electrical path between the test system and the circuits on the wafer, thereby permitting the testing and validation of the circuits at the wafer level, usually before they are diced and packaged. It normally comprises a PCB and some form of contact elements, usually metallic. A semiconductor manufacturer will typically require a new probe card for each new device wafer and ...

Technology Companies Established In 1940
Technology is the application of Conceptual model, conceptual knowledge to achieve practical goals, especially in a reproducible way. The word ''technology'' can also mean the products resulting from such efforts, including both tangible tools such as Kitchen utensil, utensils or machines, and intangible ones such as software. Technology plays a critical role in science, engineering, and everyday life. Technological advancements have led to significant changes in society. The earliest known technology is the stone tool, used during prehistory, followed by the control of fire—which in turn contributed to the Brain size, growth of the human brain and the development of language during the Pleistocene, Ice Age, according to the cooking hypothesis. The invention of the wheel in the Bronze Age allowed greater travel and the creation of more complex machines. More recent technological inventions, including the printing press, telephone, and the Internet, have lowered barriers to ...

Companies Formerly Listed On The Nasdaq
A company, abbreviated as co., is a legal entity representing an association of legal people, whether natural, juridical or a mixture of both, with a specific objective. Company members share a common purpose and unite to achieve specific, declared goals. Over time, companies have evolved to have the following features: "separate legal personality, limited liability, transferable shares, investor ownership, and a managerial hierarchy". The company, as an entity, was created by the state which granted the privilege of incorporation. Companies take various forms, such as: * voluntary associations, which may include nonprofit organizations * business entities, whose aim is to generate sales, revenue, and profit * financial entities and banks * programs or educational institutions A company can be created as a legal person so that the company itself has limited liability as members perform or fail to discharge their duties according to the publicly declared incorporation ...

LCD Manufacturing
LCD manufacturing is the process of making liquid crystal display (LCD) panels. It involves using glass and silicon substrates. Photolithography is used to pattern the substrates, and liquid crystal materials are added. In the case of a color TFT LCD, color filters are patterned in layers to make red, green, and blue pixels. Liquid crystal displays are manufactured in cleanrooms, borrowing techniques from semiconductor device manufacturing. Process A class of photolithography known as display lithography is used to etch patterns into substrates. LCD manufacturing shares some of the process with OLED manufacturing. The process flow involves multiple separate components that are joined together: a process for making a thin-film transistor (TFT) backplane, a process for making color filters, and a liquid crystal cell process. Large-scale chemical vapor deposition (CVD) systems have been used in the manufacture of LCDs. Once LCD panels are manufactured, they can be measured for col ...

Through-silicon Via
In electronic engineering, a through-silicon via (TSV) or through-chip via is a vertical electrical connection (Via (electronics), via) that passes completely through a silicon wafer or die (integrated circuit), die. TSVs are high-performance interconnect techniques used as an alternative to wire bond, wire-bond and flip chips to create 3D packages and Three-dimensional integrated circuit, 3D integrated circuits. Compared to alternatives such as Package on package, package-on-package, the interconnect and device density is substantially higher, and the length of the connections becomes shorter. Classification Dictated by the manufacturing process, there exist three different types of TSVs: ''via-first TSVs'' are fabricated before the individual component (transistors, capacitors, resistors, etc.) are patterned (front end of line, FEOL), ''via-middle TSVs'' are fabricated after the individual component are patterned but before the metal layers (Back end of line, back-end-of-li ...

Silicon
Silicon is a chemical element; it has symbol Si and atomic number 14. It is a hard, brittle crystalline solid with a blue-grey metallic lustre, and is a tetravalent metalloid (sometimes considered a non-metal) and semiconductor. It is a member of group 14 in the periodic table: carbon is above it; and germanium, tin, lead, and flerovium are below it. It is relatively unreactive. Silicon is a significant element that is essential for several physiological and metabolic processes in plants. Silicon is widely regarded as the predominant semiconductor material due to its versatile applications in various electrical devices such as transistors, solar cells, integrated circuits, and others. These may be due to its significant band gap, expansive optical transmission range, extensive absorption spectrum, surface roughening, and effective anti-reflection coating. Because of its high chemical affinity for oxygen, it was not until 1823 that Jöns Jakob Berzelius was first able to p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Integrated Circuits
An integrated circuit (IC), also known as a microchip or simply chip, is a set of electronic circuits, consisting of various electronic components (such as transistors, resistors, and capacitors) and their interconnections. These components are etched onto a small, flat piece ("chip") of semiconductor material, usually silicon. Integrated circuits are used in a wide range of electronic devices, including computers, smartphones, and televisions, to perform various functions such as processing and storing information. They have greatly impacted the field of electronics by enabling device miniaturization and enhanced functionality. Integrated circuits are orders of magnitude smaller, faster, and less expensive than those constructed of discrete components, allowing a large transistor count. The IC's mass production capability, reliability, and building-block approach to integrated circuit design have ensured the rapid adoption of standardized ICs in place of designs using discre ...
