Abstract:
A method for planarizing a high step-height integrated circuit structure within an integrated circuit. There is first formed upon a semiconductor substrate a high step-height integrated circuit structure. Formed then adjoining the high step-height integrated circuit structure is a patterned Global Planarization Dielectric (GPD) layer. There is then formed upon the exposed surfaces of the semiconductor substrate, the high step-height integrated circuit structure and the patterned Global Planarization Dielectric (GPD) layer a reflowable dielectric layer. Finally, the reflowable dielectric layer is reflowed.
