Abstract: PURPOSE: A method for fabricating an electronic device is provided to reduce byproducts by performing a heat treatment after a hole passing through an interlayer dielectric is formed and by discharging the byproduct on an interface between an etching stopper layer and the interlayer dielectric. CONSTITUTION: The interlayer dielectric is selectively eliminated. A hole is formed that passes through the interlayer dielectric and reaches the etching stopper layer(4). A heat treatment is performed while the hole is open.

The interlayer dielectric and the buried plug are selectively removed by using chemical amplification type resist as an etching mask, and a groove pattern for burying an upper interconnection is formed in the upper main surface of the interlayer dielectric. The buried plug left in the hole is eliminated to connect the groove pattern with the hole. The etching stopper layer is selectively removed to expose a lower interconnection(20). The groove pattern and the hole are filled with a conductive material to form the upper interconnection and a contact part simultaneously.
