Description

Title:Interference
Author(s):Maduzia, Joe
Subject(s):Mechanical Science and Engineering
Abstract:This image shows a 4" silicon wafer with a thermal silicon dioxide film grown. The wafer is still inside a long quarz tube furnace at MNMS Cleanroom where the film was grown. This film is uneven. The variation in film thickness is seen as changing colors. This image also shows the angle dependent light reflectivity of the quartz tube. Quartz is typically transparent to visible light, but at low angles quartz reflects the colored light of the wafer back toward the camera.The same effect can be seen on pavement on the road. If you look far enough you can typically see a reflection of the sky on the road ahead, as concrete and other materials are reflective at certain angles.
