    摘要: A method of manufacturing a DNA (deoxyribonucleic acid) chip is provided. The DNA chip has a plurality of transistors formed on a substrate and an organic layer and a DNA probe sequentially stacked on a gate of the transistor. The method includes forming an inter-layer insulation layer on the substrate to cover the transistors, planarizing the inter-layer insulation layer, forming at least two contact holes exposing gate electrodes of the transistors in the inter-layer insulation layer, selectively forming organic layers on the exposed gate electrodes, attaching a first DFR (dry film resist) layer to the upper surface of the inter-layer insulation layer to cover the contact holes, removing a portion of the first DFR layer covering a first contact hole among the contact holes, attaching a first DNA probe to the organic layers in the first contact hole, and removing a remaining portion of the first DFR layer.
