Printed electronics, printed electronics that is based on the principle. Some specific, science and technology is the use of traditional printing technology to produce electronic devices and systems. For most people, printed electronics is a very strange term. Even possible, even experts in the field of e-learning may not have heard of the term printed electronics. Many people will printed electronics with traditional printing technologies can not tell, or confused with electronic printing. But the fact is videotex traditional printing printing, printing even Shanghai is only a branch of traditional print media printing, but increased use of electronic means such as electronic publishing and computer only. So overall not printed electronics " electronic printing. " And if printed electronics to find a relatively similar areas, it should be made an integrated electronic system, just the manufacturing process of integrated circuit manufacturing work into print - Arts. Modern silicon integrated circuit manufacturing printed Shanghai has become extremely complicated technical field, from the preparation of single crystal silicon substrate material, in addition to the formation of crystal violet lithography apparatus at the cost of more than $ million on a silicon single crystal. Such a high investment in the production of integrated circuits has become the world's only a few companies can afford industry. In sharp contrast to the simplicity of printing production techniques. Compare the basic manufacturing processes and printing processes for manufacturing integrated circuits.
