摘要： A method of forming a silicon nitride layer in a semiconductor device manufacturing process. The silicon nitride layer (SixNyHz) is formed by PE-CVD technique at low temperature to have at most 0.35 hydrogen composition. The resulting silicon nitride layer has substantially no Si—H bonding as compared with a silicon nitride layer formed at high temperature, thereby reducing thermal stress variation during annealing. The resulting silicon nitride layer exhibits reduced thermal stress variation before and after deposition, preventing a popping phenomenon and reducing the stress applied to the underlying layer.

摘要： In a method of manufacturing a phase-changeable memory device, a lower electrode is formed on a substrate. Silicon oxynitride is then deposited on the lower electrode at a temperature of about 450° C. to about 650° C. to form an insulating interlayer that is relatively dense on the lower electrode. The insulating interlayer is partially etched to form a contact hole exposing the lower electrode. A phase-changeable material layer pattern filling up the contact hole is formed on the insulating interlayer such that the phase-changeable material layer pattern makes contact with the lower electrode.

摘要： A stacked semiconductor device includes a first gate structure formed on a substrate, a first insulating interlayer covering the first gate structure on the substrate, a first active pattern formed through and on the first insulating interlayer and contacting the substrate, a second gate structure formed on the first active pattern and the first insulating interlayer, a buffer layer covering the second gate structure on the first active pattern and the first insulating interlayer, a second insulating interlayer formed on the buffer layer, and a contact plug formed through the first and second insulating interlayers, which contacts with the substrate and is insulated from the second gate structure by the buffer layer. Operation failures of a transistor in the stacked semiconductor device can be reduced because the buffer layer prevents a word line from being electrically connected to the contact plug.

摘要： Methods of forming trench isolations are provided. A method includes providing a semiconductor substrate having a cell array region and a peripheral region. At least one cell trench in the cell array region and at least one peripheral trench wider than the cell trench in the peripheral region of the substrate are formed. The cell and the peripheral trenches have sidewalls. A first dielectric layer that partially fills the cell and peripheral trenches is formed over the substrate. At least one photoresist pattern that exposes at least the cell trench partially filled with the first dielectric layer is formed over the substrate. The first dielectric layer formed on the sidewalls of the exposed cell trench is etched by using the photoresist pattern as a etch mask. Subsequently, the photoresist pattern is removed. A second dielectric layer filling the cell and peripheral trenches is formed over the substrate where the photoresist pattern is removed.

摘要： Methods of forming capacitors include forming a first mold layer and a second mold layer on a substrate, forming storage electrodes through the mold layers, the storage electrodes arranged in rows extending in a first direction and spaced apart from adjacent storage electrodes along the first direction by a first interval. The storage electrodes are spaced apart from adjacent storage electrodes along a second direction oblique to the first direction by a second interval smaller than the first interval. First and second sacrificial layers are formed on the storage electrodes layer partially filling up a gap between adjacent storage electrodes along the first direction and filling up a gap between the adjacent storage electrodes along the second direction. Sacrificial spacers may be formed on sidewalls of the storage electrodes by etching the sacrificial layers. The second mold layer may be etched using the sacrificial spacers as etching masks to define a plurality of stabilizing structures. Resulting devices are also disclosed.
