摘要
Also disclosed herein are nanocrystalline diamond layers and methods for using them for use in forming semiconductor devices. The device may comprise a substrate having a processing surface and a support surface, a device layer formed on the processing surface, and a nanocrystalline diamond layer formed on the processing layer, wherein the nanocrystalline diamond layer has an average crystal grain size of 2 nm to 5 nm. . The method includes positioning a substrate in a process chamber, depositing a device layer on a processing surface, depositing a nanocrystalline diamond layer on the device layer, the nanocrystalline diamond layer having an average crystal grain size of 2 nm to 5 nm. Steps, patterning and etching the nanocrystalline diamond layer, etching the device layer to form a feature, and ashing the nanocrystalline diamond layer from the surface of the device layer.
