Design and optimization of Schottky diodes in CMOS technology with application to passive RFID systems Auto-ID lab Adelaide

Overview Introduction. Design and layout of Schottky diode. Modelling of designed SBD. Applications. Fabrication and measurements. Conclusion.

The General RFID Idea Normally a very weak reply is obtained The black spot

Example Applications What can you do with this technology ? Supply chain benefits – Reduce out of stocks, reduce inventory, speed up delivery, check freshness, track and trace, produce to demand, identify sources of diversion, identify counterfeiting, theft prediction, faster recalls Consumer benefits – Direct order from home, smart appliances, (e.g. microwave, washing machine, refrigerator), smart healthcare, assisted living New and less expected benefits – Customized products, smart recycling, checkout-less stores

Passive RFID RFID tag chip in standard CMOS technology. Low size. Low cost. Integration with existing logics and other modules. Supply sufficient operating power Metal directly deposited on N-Well. Titanium-Silicon/Tungsten-Silicon contact Functional but needs more improvements. Fabricated through MOSIS
