In semiconductor electronics fabrication technology, a self-aligned gate is a transistor manufacturing approach whereby the gate electrode of a MOSFET (metal–oxide–semiconductor field-effect transistor) is used as a mask for the doping of the source and drain regions. This technique ensures that the gate is naturally and precisely aligned ...
FlexFET is a planar, independently double-gated transistor with a damascene metal top gate MOSFET and an implanted JFET bottom gate that are self-aligned in a gate trench. . This device is highly scalable due to its sub-lithographic channel length; non-implanted ultra-shallow source and drain extensions; non-epi raised source and drain regions; and gate-last fl
N-channel, metal gate processes (in the 1970s) imposed a very high standard of cleanliness (absence of sodium) – difficult to achieve in that timeframe, resulting in high manufacturing costs. Polysilicon gates – while sensitive to the same phenomenon, could be exposed to small amounts of HCl gas during subsequent high-temperature processing ...
U.S. manufacturing slumped further in June, reaching levels last seen when the nation was reeling from the initial wave of the COVID-19 pandemic, but price pressures at the factory gate continued ...
Drawing of round head rivets, 1898 A typical technical drawing of a universal head solid rivet Riveters work on the Liberty ship SS John W. Brown (December 2014).. Rivet holes have been found in Egyptian spearheads dating back to the Naqada culture of between 4400 and 3000 B.C. Archeologists have also uncovered many Bronze Age swords and daggers with rivet holes where the handles would have been.
Sinclair ZX81 ULA. A gate array is an approach to the design and manufacture of application-specific integrated circuits (ASICs) using a prefabricated chip with components that are later interconnected into logic devices (e.g. NAND gates, flip-flops, etc.) according to custom order by adding metal interconnect layers in the factory.
An analogy may be found in a water system that employs a water main (sprue) and smaller pipes (runners) to individual houses. The gate is the location at which the molten plastic enters the mold cavity and is often evidenced by a small nub or projection (the "gate mark") on the molded piece.
