Electronics Business Insurance

Whether your business produces consumer products, communications equipment, computer parts, or other technological or electronic components, working with electronics can expose your company to some specialized risks. You also must manage the risks that are common to many small businesses like property damage to your place of business or loss of important documents, files and records. Learn about the insurance coverages electronics businesses typically need, and most often purchase, from The Hartford.

1. 1. Introduction What is transparent electronics?  In transparent electronics the usual opaque semiconductor materials forming the basis for electronic device fabrication is replaced with transparent materials.
2. 2.  There are two technologies which preceded and underlie transparent electronics: 1. Transparent Conducting Oxides (TCOs) 2. Thin Film Transistors (TFTs)
3. 3. Transparent Conducting Oxides TCOs)  TCOs constitute an unusual class of materials possessing two physical properties (generally considered mutually exclusive): 1. High optical transparency. ( Eg>3.1eV) 2. High electrical conductivity.
4. 4. Transparent electronic devices Transparent Passive devices Transparent Active devices
5. 5. Transparent Passive devices  Transparent Thin Film Resistors  Transparent Thin Film Capacitors  Transparent Thin Film Inductors
6. 6. Transparent Thin Film Resistors
7. 7. Transparent Thin Film Capacitors

11. 11. Transparent Thin Film Transistors Constitutes the heart of transparent electronics Channel is formed from highly insulating, wide band gap transparent semiconductor(ZnO). Source, drain and gate contacts are made from highly conductive TCO (ITO). Two possible configurations are: a) Bottom gate b) Top gate
12. 12. Possible structure, (a) Bottom gate, and (b) Top gate.
13. 13. Operation of a bottom gate TFT
14. 14. Strengths and Weaknesses Strengths Weaknesses Visible transparency High resistance of TCO’s Large area Lack of complementary devices Low cost (solution based deposition and printing) Low temperature processing Free real estate Passive availability (R & C) Robust stable inorganic materials Safe, nontoxic materials Technological immaturity
15. 15. Applications Active Matrix LCD (AMLCD). Active Matrix Organic Light Emitting Device display backplane (AMOLED). Value added glass. Transparent electronics on opaque substrates.
16. 16. UV detectors and arrays • Transparent solar cells • UV detectors for spectrally resolved imaging. • Security applications: Invisible cameras and Invisible RFID’s
17. 17. Conclusion • Started as a mere electrical device technology during world war 2, transparent electronics now holds the key for many future advancements in security, entertainment efficient utilization of energy.
