Thin Films Research


Thin film research is centered in two main areas; thin films for microelectronic applications and thin films for photonic applications.  Below I list the various research projects we have with links to those individual projects for more information.




Microelectronics Applications
  -  research in this area is centered on low dielectric constant materials.  Here we are mainly interested in nanoporous materials and their chemical, mechanical, thermal, electrical, and interfacial properties.



Mechanical Properties  -  measurement and prediction of eleastic modulus as a function of porosity


Thermal Properties  -  measurement and prediction of thermal conductivity as a function of porosity


Electrical Properties  -  diffusion of metals and other dopants into nanoporous materials


Interfacial Properties  -  stability of thin films deposited on nanoporous substrates


Chemical Properties  -  reactive ion etching behavior of nanoporous materials

Processing Issues - processing of nanoporous materials, control of porosity, thickness etc.

 




Photonics Applications - research in this area is focused on materials for integrated optical components and light emitting diodes.  The work involves dense and nanoporous organic, inorganic and hybrid materials.


Integrated Optical Waveguides - fabrication of integrated optical waveguides for telecommunications applications and for on-chip optical communications.  Fabrication processes include solid-state ionic diffusion and plasma deposition.



Integrated Optical Components -
development of micromirrors, gratings, etc. associated with making the analog of an optical integrated circuit or optical printed circuit board
