Abstract: A fabricating method of a stop layer includes providing a substrate. The substrate is divided into a memory region and a peripheral circuit region. Two conductive lines are disposed within the peripheral circuit region. Then, an atomic layer deposition is performed to form a silicon nitride layer to cover the conductive lines. Later, after forming the silicon nitride layer, a silicon carbon nitride layer is formed to cover the silicon nitride layer. The silicon carbon nitride layer serves as a stop layer.

Abstract: A method of fabricating a metal-insulator-metal capacitor includes providing a dielectric layer. The dielectric layer is etched to form a first hole including a first convex profile bulging into the dielectric layer. Subsequently, the dielectric layer is etched to form a second hole including a second convex profile bulging into the dielectric layer. A first metal layer is formed to conformally cover the capacitor trench. An insulating layer is formed to cover the first metal layer. Finally, a second metal layer is formed covering the insulating layer.

Abstract: A manufacturing method for a shallow trench isolation. First, a substrate is provided, a hard mask layer and a patterned photoresist layer are sequentially formed on the substrate, at least one trench is then formed in the substrate through an etching process, the hard mask layer is removed. Afterwards, a filler is formed at least in the trench and a planarization process is then performed on the filler. Since the planarization process is performed only on the filler, so the dishing phenomenon can effectively be avoided.
