    摘要: A first insulating interlayer is formed on a substrate including first and second regions. The first insulating interlayer has top surface, a height of which is greater in the first region than in the second region. A first planarization stop layer and a second insulating interlayer are formed. The second insulating interlayer is planarized until the first planarization stop layer is exposed. The first planarization stop layer and the first and second insulating interlayers in the second region are removed to expose the substrate. A lower mold structure including first insulation layer patterns, first sacrificial layer patterns and a second planarization stop layer pattern is formed. The first insulation layer patterns and the first sacrificial layer patterns are alternately and repeatedly formed on the substrate, and a second planarization stop layer pattern is formed on the first insulation layer pattern.

    摘要: Example embodiments relate to a method of treating a substrate after performing a cleaning step with a liquid chemical in a single substrate spin cleaner. A method of treating a substrate according to example embodiments may include forming a film of deionized water on a surface of the substrate during rinsing, and drying the substrate by supplying a drying gas to the water film on the surface of the substrate. When rinsing the substrate, the rotating speed of the substrate may be reduced to about 50 rpm or less to form a film of water on the surface of the substrate. The film of water may shield the surface of the substrate from direct exposure to atmospheric air. The film of water may be maintained on the surface of the substrate when commencing the supply of the drying gas. Consequently, the number of water marks on the dried substrate may be reduced or prevented.
