Nanofabrication Through the Replication of a Block Copolymer Template

Image courtesy Young-Rae HongAn example of nanofabrication through the replication of a block copolymer thin film template.  Top portion of the image shows an array of gold dots, 30 nm diameter and 18 nm thick, on a silicon wafer substrate.  The lower potion shows the mask through which these dots were deposited:  a 10 nm-thick silicon nitride membrane, perforated with holes of 30 nm diameter.
