Course Description

Today, literally hundreds of polymeric materials have found widespread use in the manufacture of microwave, electronic, and photonic systems . This is due in part to their structures that can be tailored to provide a wide range of physical properties, and also due to the ease of processing and fabrication of polymers.

This course presents some important applications of polymers in electronic and photonic applications. The course begins with an overview of polymer materials which includes in detail both advantages and disadvantages of polymers and comparison of polymers with other materials. It also presents the development of intrinsically conducting polymers that exhibit conductivities similar to metal. Following this, it explores the lithography processing techniques associated with the use of polymer materials such as processing conditions, photolithography methods, and patterning methods. Described in detail are the characteristics of polymer resists and issues of packaging and chip materials to illustrate the importance of polymer materials and processing in attaining VLSI devices in electronic applications. In addition, it addresses significant issues regarding nonlinear optical polymers and microwave loss in polymers, followed by a discussion of processing and fabrication techniques for integrated optical waveguides, an emerging technology for polymers in photonic applications. And finally, the course outlines recent advances in developments and applications of polymer based materials. BACK
