The electronics industry provides circuits and active electrical components. Integrated circuits that are used in electronic devices are built on wafers made of semiconductor materials. Silicon is the most widely used semiconducting material. Silicon wafers undergo extreme cleaning procedures prior to chip manufacturing. The cleanliness of the silicon wafers is checked using contact angle measurements. Polymers are also used in the electronics industry as insulating layers in the fabrication of chips and chip carriers. The quality and uniformity of the coatings is of the utmost importance.
