Semiconductor wafers. Scattered semiconductor wafers viewed from above. Wafers are divided up into blocks to make the integrated circuits ('chips') used in electronic devices. Integrated circuits are made by impregnating the wafer with impurities to create transistors. Tens of thousands of transistors can be fitted on a single chip and connected by conducting pathways.
