METHOD OF PROVIDING A PLANARIZED POLYMER COATING ON A SUBSTRATE WAFER

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 planar...

Zusammenfassung:	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.
