Abstract: A substrate including plasmonic continuous film with curved surface and a method for manufacturing the same. More particularly, a substrate for an ultrasensitive spectroscopic sensor includes bowl-shaped plasmonic curved nanodimples and spiked plasmonic nanotips formed at contact points between the nanodimples at the same time, thereby greatly increasing the total volume of hotspots and being capable of concentrating and analyzing an extremely small amount of a sample.
