Abstract:
In some embodiments, a method of forming an opening in a material comprises forming RIM over target material. Radiation is impinged onto the RIM through a masking tool over a continuous area of the RIM under which a target-material opening will be formed. The masking tool during the impinging allows more radiation there-through onto a mid-portion of the continuous area of the RIM in a vertical cross-section than onto laterally-opposing portions of the continuous area of the RIM that are laterally-outward of the mid-portion of the RIM in the vertical cross-section. After the impinging, the RIM is developed to form a RIM opening that has at least one pair of laterally-opposing ledges laterally-outward of the mid-portion of the RIM in the vertical cross-section elevationally between a top and a bottom of the RIM opening. The developed RIM is used as masking material while etching the target material through the RIM opening to form the target-material opening to have at least one pair of laterally-opposing ledges laterally-outward of a mid-portion in the target-material opening in the vertical cross-section elevationally between a top and a bottom of the target-material opening. Other aspects and constructions independent of manufacture are disclosed.

Claim (Index 16):
An integrated circuit structure comprising:\n an insulating material above integrated circuitry, the insulating material having an opening therein that extends elevationally inward to an upper conductive node of the integrated circuitry, the opening having multiple annular ledges elevationally between a top and a bottom of the opening; a conductive line of a redistribution layer (RDL) above the insulating material, the RDL conductive line extending elevationally inward into the opening over the multiple annular ledges and being directly electrically coupled to the upper conductive node, all conductive material of the RDL conductive line that is in the opening less-than-filling the opening; a first insulative material in the opening in the insulating material; and a second insulative material in the opening in the insulating material, the second insulative material being atop and directly against the first insulative material in the opening in the insulating material and being of different composition from that of the first insulative material.
