Abstract:
A method for manufacturing a semiconductor device includes providing a substrate structure including a substrate, a plurality of fins on the substrate, a hardmask layer on the fins, and a first insulating layer on the substrate for isolating the fins. The first insulating layer has an upper surface substantially flush with an upper surface of the hardmask layer. The method also includes etching back the first insulating layer to form a second insulating layer having an upper surface lower than a bottom surface of the hardmask layer, performing an oxidation process or an annealing process on the second insulating layer, removing the hardmask layer after performing the oxidation process or the annealing process, and etching back the second insulating layer to form an insulating region having an upper surface lower than an upper surface of the fins.

Claim (Index 11):
A semiconductor device, comprising:\n a substrate; a plurality of fins on the substrate and having rounded corners and edges on an upper portion of the fins; a hardmask layer on the fins; and an insulating region on the substrate for isolating the fins and having an upper surface lower than an upper surface of the fins.
