Classification: CPC H | IPC H

Claim 15:
16. A method of forming a semiconductor device structure, comprising:
patterning a substrate to define a plurality of first fins spaced apart from each other along a first direction;
cutting the plurality of first fins along the first direction to form a plurality of second fins and a plurality of third fins spaced apart from the plurality of second fins along a second direction different from the first direction;
filling a first space between the plurality of second fins and the plurality of third fins and a second space between two adjacent second fins of the plurality of second fins and a third space between two adjacent third fins of the plurality of third fins with an insulating layer;
recessing the insulating layer, so that a top surface of the recessed insulating layer lower than top surfaces of the plurality of second fins and the plurality of third fins; and
forming a capping structure to cover the top surface of the recessed insulating layer.
