providing a first layer above a substrate;
providing a block copolymer layer above the first layer;
converting the block copolymer layer to a mask by selectively removing domains of the block copolymer layer;
etching pores through the first layer in regions exposed by the mask; and
forming a channel through the substrate, the channel being configured to provide fluid communication between a first and a second end of the channel, the first end of the channel being directly below the etched pores of the first layer,
whereby fluid passing through the channel and the pores is filtered by the pores, when the filter is in use.
