摘要:
In a method of manufacturing a semiconductor device such as a flash memory device, an insulating pattern having an opening is formed to partially expose a surface of a substrate. A first silicon layer is formed on the exposed surface portion of the substrate and the insulating pattern. The first silicon layer has an opened seam overlying the previously exposed portion of the substrate. A heat treatment on the substrate is performed at a temperature sufficient to induce silicon migration so as to cause the opened seam to be closed via the silicon migration. A second silicon layer is then formed on the first silicon layer. Thus, surface profile of a floating gate electrode obtained from the first and second silicon layers may be improved.
摘要:
In methods of forming an oxide layer and an oxynitride layer, a substrate is loaded into a reaction chamber having a first pressure and a first temperature. The oxide layer is formed on the substrate using a reaction gas while increasing a temperature of the reaction chamber from the first temperature to a second temperature under a second pressure. Additionally, the oxide layer is nitrified in the reaction chamber to form the oxynitride layer on the substrate. When the oxide layer and/or the oxynitride layer are formed on the substrate, minute patterns of a semiconductor device, for example a DRAM device, an SRAM device or an LOGIC device may be easily formed on the oxide layer or the oxynitride layer.
