	Technique for modifying an integrated circuit layout - Patent 5231590
		The schematic circuit is then converted to a circuit layout by designing a number of masks which, when used to make an integrated circuit chip, implements the circuit initially designed as a schematic diagram.
		Integrated circuit packaging technology is not allowing the pads to be reduced in size as much as process technology is allowing the remaining portions of the circuit to be shrunk.
		The result is that circuit elements in the pad ring 13 must be rearranged in order to accommodate the relatively larger size pads that result after the overall circuit layout size is reduced.

	IP Australia : What is Intellectual Property? > Circuit Layout Rights
		Circuit layouts are usually highly complex and the intellectual effort in creating an original layout may be considerable and of great value.
		An integrated circuit or chip made from the plans is the key to the operation of all kinds of electronic devices, from heart pacemakers to personal computers.
		Accordingly, rights in an original layout subsist for 10 years from the first commercial exploitation, provided this occurs within 10 years from creation of the layout or 10 years from the year in which it was made, if not commercially exploited.

	PCB Layout - Printed Circuit Board Layout and Design
		The connections on the PCB should be identical to the circuit diagram, but while the circuit diagram is arranged to be readable, the PCB layout is arranged to be functional, so there is rarely any visible correlation between the circuit and the layout.
		These days most circuit boards are automatically assembled and tested - but you will still have people working on your circuit boards, and having a quality design can make all the difference between a product that is pleasant to work on and one that they will hate.
		The PCB layout also needs to take account of EMI and ESD compliance and we have a seperate page on some techniques that we use to get our PCBs to comply.

	Integrated Circuit - Background, How Integrated Circuit, Design, Raw Materials, The Manufacturing, Quality Control
		An integrated circuit, commonly referred to as an IC, is a microscopic array of electronic circuits and components that has been diffused or implanted onto the surface of a single crystal, or chip, of semiconducting material such as silicon.
		It is called an integrated circuit because the components, circuits, and base material are all made together, or integrated, out of a single piece of silicon, as opposed to a discrete circuit in which the components are made separately from different materials and assembled later.
		The first integrated circuits were created in the late 1950s in response to a demand from the military for miniaturized electronics to be used in missile control systems.

	Circuit Layout
		A "stick" diagram is a simplified layout form which does contain the information related to each of the process steps, but does not contain the actual size of the individual features.
		The objective is typically to layout the circuit using a minumal area.
		The layout also contains two cross-overs; one to connect the two inverters into a flipflop and another one to connect the output of the flipflop to a large area contact pad.

	Integrated circuit layout - Wikipedia, the free encyclopedia
		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.
		IC layout may be created by automatic EDA tools, such as place and route tools or schematic driven layout tools, 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".
