Below is a picture of an Integrated Circuit (IC), also called a microchip. This particular IC is an old erasable programmable read-only memory chip. The IC package has a window that allows the memory to be erased by exposing the chip to ultraviolet light. This window also allows us to see the tiny silicon chip itself (inset image in upper right). Notice the tiny wires that connect the chip circuitry to the electrical contacts (the ‘legs’) of the IC package.

Close this window when finished.
