Integrated circuit layout, also known IC layout or IC mask layout is the representation of an integrated circuit in terms of planar geometric shapes that correspond to shapes actually drawn on photomasks used in semiconductor device fabrication. Optical Microscope image of an integrated circuit showing defects in the aluminium layer deposition. ... As used in photolithography, a photomask is typically an optically transparent fused quartz blank imprinted with a pattern defined with chrome metal. ... Nasas Glenn Research Center clean room. ...
IC layout may be created by automatic EDA tools, such as place and route tools or [[schematic driven layout], or created and edited by an IC designer manually by means of IC layout editors. The later manual operation is informally known as "polygon pushing". Electronic design automation (EDA) is the category of tools for designing and producing electronic systems ranging from printed circuit boards (PCBs) to integrated circuits. ... Place and Route is a stage in design of: Printed circuit boards at which components are graphically placed on the board and the wires drawn between them. ... Look up Polygon on Wiktionary, the free dictionary For other use please see Polygon (disambiguation) A polygon (literally many angle, see Wiktionary for the etymology) is a closed planar path composed of a finite number of sequential line segments. ...
If a circuitlayout is designed by combining ordinary, common or knowncomponents or interconnections, protection for the circuitlayout shall beextended to the combination as a whole that has met the requirements prescribedin the preceding Paragraph.
In a case of an infringement of circuitlayout rights, the owner of the circuitlayout rights may request compensation for damages and request for a removal of the infringement; if a threat of infringement can be proved, a prevention of infringement may be requested.
An injured party as set forth in Paragraph 1, Article 29 of this Ac may request for the destruction of integratedcircuits containing the infringing circuitlayouts, and the publication of the contents of the court judgment, in whole or in part, in a newspaper with costs to be borne by the losing party.
The integratedcircuit was first conceived by a radar scientist, Geoffrey W.A. Dummer (born 1909), working for the Royal Radar Establishment of the British Ministry of Defence, and published in Washington DC on May 7, 1952.
These digits are fed to the dialer integratedcircuit 14 in serial fashion, in binary coded decimal form, on four input lines 15 from the diode matrix encoder 16, which in turn receives key depression input signals on 12 lines 17 from the 12 key pushbutton keyboard 18.
The output of the dialer integratedcircuit 14 to the relay driver 13 is a group of pulses, at a rate of 10 or 20 per second, corresponding in number to the numerical value of the corresponding depressed key of the keyboard 18.
