Claim 7:
8. A semiconductor device structure, comprising:
a plurality of first fins protruding from a substrate, spaced apart from each other along a first direction;
a plurality of second fins protruding from the substrate, spaced apart from each other along the first direction and spaced apart from the plurality of first fins along a second direction different from the first direction; and
an insulating structure formed over the substrate and extending along the first direction and the second direction, comprising:
a first insulating layer having a first portion separating the plurality of first fins from the plurality of second fins, a second portion extending from the first portion and between two adjacent first fins of the plurality of first fins, and a third portion extending from the first portion and between two adjacent second fins of the plurality of second fins; and
a capping structure covering top surfaces of the first portion, the second portion, and the third portion of the first insulating layer.
