    摘要: In a method of manufacturing a semiconductor device such as a SONOS type semiconductor device, a trench is formed on a substrate. An isolation layer protruding from the substrate is formed to fill the trench. After a first layer is formed on the substrate, a preliminary second layer pattern is formed on the first layer. The preliminary second layer pattern has an upper face substantially lower than or substantially equal to an upper face of the isolation layer. A third layer is formed on the preliminary second layer and the isolation layer. A fourth layer is formed on the third layer. The fourth layer, the third layer, the preliminary second layer pattern and the first layer are partially etched to form a gate structure on the substrate. Source/drain regions are formed at portions of the substrate adjacent to the gate structure.

    摘要: Methods for forming a mold for a storage electrode in a semiconductor device include forming an interlayer dielectric layer including a contact plug on a substrate. A first mold dielectric layer is formed of a first material on the interlayer dielectric layer. A second mold dielectric layer is formed of a second material on the first mold dielectric layer. The second material has a different etch selectivity than the first material. A first opening is formed that penetrates the first and second mold dielectric layers. The first opening is dry etched to define a second opening having a larger width in the first mold dielectric layer than in the second mold dielectric layer based on the different etch selectivity of the first and second mold dielectric layers to define the mold for the storage electrode.

    摘要: A method of removing a photoresist may include permeating supercritical carbon dioxide into the photoresist on a substrate having a conductive structure including a metal. The photoresist permeating the supercritical carbon dioxide may be easily removable. The photoresist permeating the supercritical carbon dioxide may be removed using a photoresist cleaning solution from the substrate. The photoresist cleaning solution may include an alkanolamine solution of about 8 percent by weight to about 20 percent by weight, a polar organic solution of about 25 percent by weight to about 40 percent by weight, a reducing agent of about 0.5 percent by weight to about 3 percent by weight with the remainder being water. The photoresist may be easily removed without damaging the conductive structure in a plasma process.
