Patent ID: 8518829

Claim:
A method of forming a nanopore array, the method comprising: patterning a front layer of a substrate to form front trenches, the substrate including a buried layer disposed between the front layer and a back layer; depositing a membrane layer over the patterned front layer and in the front trenches; patterning the back layer and the buried layer to form back trenches, the back trenches being aligned with the front trenches; forming a plurality of nanopores of the nanopore array through the membrane layer; depositing a sacrificial material in the front trenches and the back trenches; depositing front and back insulating layers over the sacrificial material; and heating the sacrificial material to a decomposition temperature of the sacrificial material to remove the sacrificial material and form pairs of front and back channels without bonding the substrate, wherein the front channel of each channel pair is connected to the back channel of its respective channel pair by an individual nanopore.
