Semiconductors (707/768)

Eight Major Steps to Semiconductor Fabrication, Part 6: The Addition of Electrical Properties

May 27, 2015

Did you know that semiconductors are miniature high-rise buildings?

If you get a chance to see a cross section of a semiconductor chip under a high-resolution electron microscope, you will see layer after layer of materials piled up like a skyscraper.

To fabricate such structures, the photolithography and etching processes (which we discussed previously), along with a few others, are repeated a few hundred times until layers of thin film material result in a semiconductor chip.

Today, we will be going over this “thin-film process,” in which a semiconductor chip gets its electrical properties.
