Typical hydrogen applications in the electronics industry include circuit manufacture, semiconductor production, quartz melting, polysilicon production, epitax wafer production, and fiber optic production. Due to the inherent requirement for high purity, electronics companies generally require liquid hydrogen, gas vaporized from liquid, or lower purity H₂ that is purified at the customer's site. Below is an illustration of hydrogen usage within the electronics industry:
