Method to provide a layer with uniform etch characteristics

The present invention includes a method and a composition to form a layer on a substrate having uniform etch characteristics. To that end, the method includes controlling variations in the characteristics of a solid layer, such etch characteristics over the area of the solid layer as a function of t...

Zusammenfassung:	The present invention includes a method and a composition to form a layer on a substrate having uniform etch characteristics. To that end, the method includes controlling variations in the characteristics of a solid layer, such etch characteristics over the area of the solid layer as a function of the relative rates of evaporation of the liquid components that comprise the composition from which the solid layer is formed.
