Silicon Galaxy

Camera: Canon Eos R8

Lens: Canon RF100-400 F5.6-8 with 27mm extension & Raynox DCR-250

This is a silicon wafer used in the semiconductor industry, this particular one was used for testing and has a unique appearance, as well as incredible colors at high magnification.

From a distance while having an interesting appearance the intricacy of it is still well out of view, or as a friend of mine said, plain on the surface, but bursting with colors within. With most of the following images being over 2x magnification a grain of rice would nearly fill the frame.

All of these shots were taken with only white light, the process used to create semiconductors on the silicon wafer involves “doping” the silicon with other elements, these test pads were most likely acting as shields being used to block other elements from being deposited onto the silicon in that area, a consequence of this process is light reflects slightly differently across the surface of the wafer, the thickness of the metal deposited also varies shifting the light constantly, and as this was only a test there are many imperfections. However at this magnification it all results in an effect that looks very similar to a galaxy.
