Method to fabricate multi-level silicon-based microstructures via use of an etching delay layer
| Abstract: New methods for fabrication of silicon microstructures have been developed. In these methods, an etching delay layer is deposited and patterned so as to provide differential control on the depth of features being etched into a substrate material. Structures having features with different depth can be formed thereby in a single etching step. |
