WebConventional cleanroom-based photolithography (PL) is one of the most widely used and established fabrication techniques in the semiconductor and microfabrication industry. However, its spatial resolution is limited by the diffraction limit of light. Web1 mrt. 2009 · When NA is near 1.0 or even greater, polarization starts to play an important role in lithographic imaging. The contrast of the image depends on the polarization state of the illumination light, the NA of the projection lens and the ratio of refractive indices of incident and transmitted medium [8].The polarization effects can be understood in terms …
