silicon dioxide layer造句

• Do you get an silicon dioxide layer on the surface?
• The planar process created a flat surface structure protected with an insulating silicon dioxide layer.
• From that point on, the reaction rate slows down because the silicon dioxide layer covers the silicon atoms.
• With thinner layers, quantum effects led to the leakage of electrons across the silicon dioxide layer, shorting out the circuit.
• As oxidation continues, the silicon dioxide layer thickens, and the distance the oxidants must travel to reach the silicon increases.
• As the silicon dioxide layer grows, it eventually prevents the oxidants from coming in direct contact with the silicon atoms.
• The team found that the silicon dioxide layer needed to be four or five atoms thick to act as an insulator.
• As companies try to pack more and more transistors, a type of switch, on a chip, they need to make the silicon dioxide layer as thin as possible.
• The Lucent group discovered by experiment that the insulating silicon dioxide layers in a chip can block a flow of current only if they are thicker than about five silicon atoms deep; if less than this, current leaks through the insulating layer and the chip is rendered useless.
