Summary
Summary
1. Inkjet, Gravure, Screen, Flexography, Offset, and their variations are
possible printing techniques for electronics.
2. Accuracy, resolution, and thickness cannot be precisely control ed without
photolithography.
3. Both organic and inorganic materials can be used. But organic materials
have advantage on flexibility.
Opportunity and Chal enge
1. Both lithography and printing are necessary now. The combination of the
two techniques might balance in high efficiency, low cost, and
environmental friendly purposes.
2. For integration, the printing speed and alignment issue are the key
development topics.
