	Metrology - Wikipedia, the free encyclopedia
		Metrology is variously described as the science of measurement; the science of accuracy and precision; the history of measures; the history of measurement and other definitions.
		Metrology was originally a study of historical measurement examining ancient, beginning of history documents from Assyria, Egypt, Greece and Roman origin.
		The studies by John Greaves (1602-1652) and Eduard Bernard (1638-1697) assert that a basic unit of measurement was used between cultures of the time based on the foot or cubit and that the basic measure of length cubed and filled with rainwater gives the basic measure of weight as a standard.

	Why Study Metrology?
		I had pursued the study of metrology because I knew it was a promising field, providing a solid method of investigating several topics of ancient history, but I did not suspect that I had involved myself in a controversy touching upon basic issues of intellectual life.
		My studies of ancient metrology have led me to two general conclusions: first, that metrology was born mainly from the practices of the international merchant class of the ancient world and, second, that metrology provided the foundation for the scientific rational vision of the world.
		The attack against metrology began in England, where classical studies had taken the aspect of dilettante exercises, and received general support in a moment in which it was felt, rightly or wrongly, that England would be worsted in a liberal world of capitalistic competition.

	Metrology For Information Technology - NISTIR 6025
		The VIM further notes that metrology includes all aspects both theoretical and practical with reference to measurements, whatever their uncertainty, and in whatever fields of science or technology they occur.
		In physical metrology, reference data is quantitative information, related to a measurable physical or chemical property of a substance or system of substances of known composition and structure, which is critically evaluated as to its reliability.
		IT metrology differs from physical metrology in several ways including; the SI dimensioning system is not as relevant; less analytical methods exist to quantify uncertainty; and the area is relatively new compared to physical metrology.

	Future Fab Intl.
		As has been frequently stated, the biggest inhibition for metrology research is the availability of materials and structures for future technology generations.
		Two papers focus on advanced metrology which is needed for process control of device structures with smaller feature sizes, new materials and new device architectures: scatterometry and model-based infrared (IR) spectroscopy.
		Metrology operations are therefore required to provide the in-line checks to ensure engineering that the devices being built are meeting the required specifications, which leads to a functional device at the end of the manufacturing process.
