John Bessant,Richard Lammingubstantial industrial base that existed for producing vacuum tubes disappeared -with one exception. That exception is, of course, the CRT, which is evident in televisions, computer displays, and a host of other information display terminals. Until recently, there was nothing that could take its place, and it 978-1-4615-9732-2

John Bessant,Richard Lammingtions of cleanliness and particle generation in the equipment area are an issue only for certain kinds of equipment like plasma-enhanced CVD and orientation film rubbing. Otherwise, the same considerations and level of performance as for semiconductor manufacturing are required.

John Bessant,Richard Lammingion of the orientational order of the material by external fields (electric, magnetic, flow gradient or anchoring field at a substrate), conferring at the same time the anisotropy of many physical properties intrinsic to liquid crystals. Further modification of a material can be made by incorporatin
