Strain engineering has been a powerful strategy in fabrication and processing of a variety of electronic, optoelectronic, and photovoltaic devices. To implement these technologies, several processes have been proposed to generate strain in semiconductors in order to improve and control their physical properties by exploiting the influence of strain on the bandgap structure. The increasing importance of this strain-induced bandgap engineering in design and fabrication of devices has raised significant challenges at both fabrication and characterization levels. The latter in particular has sparked a surge of interest in developing a variety of spectroscopic and microscopic techniques to precisely probe strain and stress in ultra small semiconductor devices and structures. Up to date, conventional strain characterization techniques suffer from a number of limitations that prevent their use in routine inspection in semiconductor device production lines. This project addresses this very issue by establishing a fast, non-destructive, and large area mapping of strain in a variety of technologically important semiconductor materials and devices. This process will be implemented by improving the newly developed Photon etc.'s system for Raman Imaging (RIMA). Through this project we will expand the capabilities of this instrument to address materials and devices inspection issues that are of critical importance for electronic, optoelectronic, photovoltaic applications. A precise study of strain in semiconductor materials will provide Photon etc. with a strong asset to develop new market opportunities in semiconductor industry.
