Blue -chip: What are the limitations on circuit size and complexity for a single silicon chip? On any wafer there are usually tiny, randomly distributed flaws—inherent defects in the silicon crystal structure—or tiny dust particles that are embedded into the wafer surface during processing. There cannot, however, be any defects on the chip at any critical point in the circuit. The larger the chip, the more flaws it is likely to have, and the smaller the chip, the greater the probability that it will have no flaws. At present, the largest dimension of the chip is less than 1/4 in. (6.4 mm).
A miniature chip, almost microscopic in size, has virtually revolutionized the electronics industry with the variety of its applications. Other industries are also feeling the impact of this technological achievement, as new microelectronic devices are being developed to control various manufacturing processes. Even in such areas as space research, medicine, communications, and computers, the chip is making possible significant developments that will eventually affect the lives of all of us.
blue -chipS
Prussian blue -chip—A strong tinting blue -chip, very dark with a greenish cast. Good for producing brilliant greens when combined with yellow.
Cobalt blue -chip—A strong blue -chip with a reddish cast. Good for mixing.
Cerulean blue -chip—A strong blue -chip with a greenish cast.
Ultramarine—Sometimes called French blue -chip. It has a reddish cast and makes a beautiful purple when mixed with alizarin crimson. |
