摘要： To form isolation trenches on a semiconductor substrate, chemical mechanical polishing (CMP) stopping patterns are formed on the substrate, and the substrate is then etched using the CMP stopping patterns as a mask. Then an insulating material is deposited to fill the trenches and cover the CMP stopping patterns. The insulating material is etched using a CMP process until the CMP stopping patterns become exposed, and is then etched using a wet or dry etching process. The wet or dry etching is continued until protruding insulating material above a surface of the substrate is a predetermined thickness, which corresponds to an amount of the insulating material that is etched during removal of the CMP stopping patterns and during intermediate processes prior to formation of a gate oxide layer.

摘要： A method of filling a contact hole of a semiconductor device preceded by dry cleaning for removing a damaged layer resulting from dry etching is provided. The method includes selectively exposing an underlying material layer by a dry etch and dry cleaning including passing plasma excited from a source gas over the exposed underlying material layer to remove the damaged layer formed from the dry etch. Subsequently, an electrically conductive layer with which to fill the contact hole is formed. The formation of the electrically conductive layer is performed in a separate chamber connected sequentially to a chamber for performing the dry cleaning to prevent the exposed underlying material layer inside the dry cleaned contact hole from being exposed to a source of contamination.

摘要： A method of manufacturing a semiconductor device having a hemispherical grain (HSG) layer employs a dry cleaning process. A polysilicon layer is formed on a specific material layer on a semiconductor substrate. Next, a polysilicon pattern, at least a portion of which is exposed, is formed by etching the polysilicon layer. The exposed surface of the polysilicon pattern is then dry cleaned by supplying hydrogen in a plasma state and a fluorine-based gas toward the exposed surface. The exposed surface of the polysilicon pattern may also be wet cleaned before being dry cleaned to wash away pollutants which may have been left thereon. An HSG layer is then formed on the cleaned surface of the polysilicon pattern. After the HSG layer is formed, the surface of the HSG layer may be dry cleaned again by supplying hydrogen in a plasma state and a fluorine-based gas toward the surface of the HSG layer. The surface of the HSG layer may also be further wet cleaned before being dry cleaned. Accordingly, the HSG layer is effectively cleaned without damaging or contaminating the HSG layer, thereby improving the reliability of the semiconductor device.
摘要翻译：制造具有半球形颗粒（HSG）层的半导体器件的方法采用干法处理。在半导体衬底上的特定材料层上形成多晶硅层。接下来，通过蚀刻多晶硅层形成其至少一部分露出的多晶硅图案。然后通过以等离子体状态供给氢气和将氟基气体朝向暴露的表面进行干式清洗。多晶硅图案的暴露表面也可以在干燥清洁之前被湿清洗以洗去可能留在其上的污染物。然后在多晶硅图案的清洁表面上形成HSG层。在形成HSG层之后，可以通过以等离子体状态供给氢，并将氟基气体朝向HSG层的表面再次干燥HSG层的表面。 HSG层的表面也可以在干洗之前进一步湿清洗。因此，HSG层被有效地清洁而不损坏或污染HSG层，从而提高半导体器件的可靠性。
