Witrynafabrication is to deposit/pattern a polymer layer (e.g., poly-imide) on the front side of the wafer. After this, the silicon wafer is etched from the back side to form arrays of silicon islands. A thinning down step may be employed to reduce the thickness of the silicon islands. Finally, another polymer WitrynaPolyimides are increasingly being used in integrated circuit manufacture. The use of a polyimide as a fabrication aid includes application of the polyimide as a photoresist, planarization layer and insulator. In these applications, the polymers are applied to a wafer substrate and subsequently cured in the desired pattern by a suitable method.
