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 ...

Andover, Massachusetts
Andover is a town in Essex County, Massachusetts, United States. It was Settler, settled in 1642 and incorporated in 1646."Andover" in ''Encyclopedia Britannica, The New Encyclopædia Britannica''. Chicago: Encyclopædia Britannica Inc., 15th ed., 1992, Vol. 1, p. 387. At the 2020 United States census, 2020 census, the population was 36,569. It is located north of Boston and south of Lawrence (Massachusetts), Lawrence. Part of the town comprises the census-designated place of Andover (CDP), Massachusetts, Andover. It is Twin towns and sister cities, twinned with its namesake: Andover, Hampshire, England. History Native Americans in the United States, Native Americans inhabited what is now northeastern Massachusetts for thousands of years prior to European colonization of the Americas. At the time of European arrival, Massachusett and Naumkeag people, Naumkeag people inhabited the area south of the Merrimack River and Pennacooks inhabited the area to the north.

Semiconductors
A semiconductor is a material with electrical conductivity between that of a conductor and an insulator. Its conductivity can be modified by adding impurities (" doping") to its crystal structure. When two regions with different doping levels are present in the same crystal, they form a semiconductor junction. The behavior of charge carriers, which include electrons, ions, and electron holes, at these junctions is the basis of diodes, transistors, and most modern electronics. Some examples of semiconductors are silicon, germanium, gallium arsenide, and elements near the so-called "metalloid staircase" on the periodic table. After silicon, gallium arsenide is the second-most common semiconductor and is used in laser diodes, solar cells, microwave-frequency integrated circuits, and others. Silicon is a critical element for fabricating most electronic circuits. Semiconductor devices can display a range of different useful properties, such as passing current more easily in one ...

Printed Circuit Board
A printed circuit board (PCB), also called printed wiring board (PWB), is a Lamination, laminated sandwich structure of electrical conduction, conductive and Insulator (electricity), insulating layers, each with a pattern of traces, planes and other features (similar to wires on a flat surface) Chemical milling, etched from one or more sheet layers of copper laminated onto or between sheet layers of a non-conductive substrate. PCBs are used to connect or Electrical wiring, "wire" Electronic component, components to one another in an electronic circuit. Electrical components may be fixed to conductive pads on the outer layers, generally by soldering, which both electrically connects and mechanically fastens the components to the board. Another manufacturing process adds Via (electronics), vias, metal-lined drilled holes that enable electrical interconnections between conductive layers, to boards with more than a single side. Printed circuit boards are used in nearly all e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Advanced Packaging (semiconductors)
Advanced packaging is the aggregation and interconnection of components before traditional integrated circuit packaging where a single die is packaged. Advanced packaging allows multiple devices, including electrical, mechanical, or semiconductor devices, to be merged and packaged as a single electronic device. Advanced packaging uses processes and techniques that are typically performed at semiconductor fabrication facilities, unlike traditional integrated circuit packaging, which does not. Advanced packaging thus sits between fabrication and traditional packaging -- or, in other terminology, between BEoL and post-fab. Advanced packaging includes multi-chip modules, 3D ICs, 2.5D ICs, heterogeneous integration, fan-out wafer-level packaging, system-in-package, quilt packaging, combining logic (processors) and memory in a single package, die stacking, wafer bonding/stacking, several chiplet A chiplet is a tiny integrated circuit (IC) that contains a well-defined subset of ...

Leveraged Buyout
A leveraged buyout (LBO) is the acquisition of a company using a significant proportion of borrowed money (Leverage (finance), leverage) to fund the acquisition with the remainder of the purchase price funded with private equity. The assets of the acquired company are often used as collateral for the financing, along with any equity contributed by the acquiror. While corporate acquisitions often employ leverage to finance the purchase of the target, the term "leveraged buyout" is typically only employed when the acquiror is a financial sponsor (a private equity investment firm). The use of debt, which normally has a lower cost of capital than Equity (finance), equity, serves to reduce the overall cost of financing for the acquisition and enhance returns for the private equity investor. The equity investor can increase their projected returns by employing more leverage, creating incentives to maximize the proportion of debt relative to equity (i.e., debt-to-equity ratio). Whi ...
