    • A method for manufacturing a semiconductor device is provided to form a fine pattern through a simple method using self-aligned double patterning. A first oxide layer pattern(20a) is formed on a silicon substrate. The silicon substrate is etched to a predetermined depth by using the first oxide layer pattern as an etch mask. A first silicon layer pattern is formed on the silicon substrate and the first oxide layer pattern in order to form a groove between the oxide layer patterns. A second oxide layer pattern(40b) having a top surface corresponding to the top surface of the first oxide layer pattern is formed in the groove. A second silicon layer pattern is formed by removing a part of the first silicon layer pattern higher than the top surface of the second oxide layer pattern. A third silicon layer pattern(30c) is formed by heating the second silicon layer pattern.

    • A method of forming a silicon channel layer and a method of manufacturing a stack memory device are provided to improve the yield of the device by forming the silicon channel layer with minimized thickness distribution variations. A second substrate(126) jointed to a first substrate(100) is prepared, and then a polishing stop layer(130) having polishing selectivity different from a silicon(140) is formed on the second substrate. A silicon layer is formed on the polishing stop layer to cover a damaged edge region of the second substrate at an ion cutting process. The silicon layer is removed by a first chemical mechanical polishing process until the surface of the polishing stop layer is exposed. The polishing stop layer is removed, and then the second substrate is polished by a second chemical mechanical polishing process to form the second substrate as a silicon channel layer of the first substrate.

    • A method for manufacturing a stack-type semiconductor apparatus is provided to improve the thickness uniformity of a surface layer used as a channel silicon layer by completely removing a polishing sacrificial layer using slurries after forming a polishing stop layer. A first substrate having a surface layer(16) and a second substrate(20) are prepared. A semiconductor structure(25) is formed on the second substrate. A polishing stop layer including oxide or nitride is formed under the surface layer. A separating layer is formed under the polishing stop layer by using a hydrogen ion implantation. The first substrate and the second substrate are joined to each other so that the surface layer is contacted to the semiconductor structure. A bulk layer of the first substrate is separated from the second substrate by using the separating layer as a cutting surface. A CMP process is performed until the polishing stop layer of the joined first substrate is exposed. The polishing stop layer is removed so that the surface layer of the joined first substrate is exposed.
