摘要:
An array of submicron silicon (Si) tubes is provided with a method for patterning submicron Si tubes. The method provides a Si substrate, and forms a silicon dioxide film overlying the Si substrate. An array of silicon dioxide rods is formed from the silicon dioxide film, and Si3N4 tubes are formed surrounding the silicon dioxide rods. The silicon dioxide rods are etched away. Then, exposed regions of the Si substrate are etched, forming Si tubes underlying the Si3N4 tubes. Finally, the Si3N4 tubes are removed.
