Abstract
A micro-fluidic device includes a plurality of heaters on a substrate for heating the substrate. The plurality of heaters define a plurality of temperature regions having distinct temperatures on the substrate. A flow feature layer is formed above the substrate to define a channel extending across the substrate through each temperature region. As fluid is repeatedly pumped within the channel, it flows from one temperature region to a next temperature region to undergo thermal cycling.
