Abstract:
Applying a photoresist layer containing a solvent to the top of an electronic wafer by spin coating. Before the layer dries the wafer is heated in an oven while controlling the solvent loss from the coating by maintaining the pressure of the solvent vapor and providing a slow solvent loss for planarizing the top surface of the polymer. The device is removed from the first oven and the bake cycle is completed in a standard convection bake oven.
Abstract:
A method of fabricating an anodic aluminum support system having an air bridge for metallic conductors. The method includes providing two or more metal layers separated by a coating of aluminum creating a multiple layer electrical interconnect system. The method includes the step of anodizing the aluminum and applying a photoresist mask to spaced portions of the top of the system. Thereafter, an etching solution is applied to the top of the system for removing the anodized aluminum, except for the portions covered by the mask, thereby providing a multilayer conductor system supported by pillars of anodic aluminum surrounded by low dielectric air.
