    • A recess is formed (dug) into the surface of a substrate to form a gate channel in the recess, so that a monocrystalline source/drain region can be formed at a level higher than that of the channel. The process includes the steps of: (a) forming an insulating layer and an oxidation preventing layer on a semiconductor substrate, and removing the oxidation preventing layer of a channel region of the transistor by an etching process; (b) forming an oxide layer on the channel region of the transistor by thermally oxidizing the semiconductor substrate, removing the oxidation preventing layer, and carrying out a first ion implantation on the whole surface; (c) removing the oxide layer, and forming the channel of the transistor in the form of a recess so as for the recess to be positioned lower than the surface of the substrate; (d) forming a gate electrode in the recess; and (e) carrying out a second ion implantation on the whole surface, and carrying out a heat treatment to form a source/drain region.
    • 在衬底的表面中形成(挖出)凹部以在凹部中形成栅极沟道,使得单晶源极/漏极区域可以形成在高于沟道的水平。 该方法包括以下步骤:(a)在半导体衬底上形成绝缘层和防氧化层,并通过蚀刻工艺除去晶体管的沟道区的氧化防止层; (b)通过热氧化半导体衬底,去除氧化防止层,并在整个表面上进行第一离子注入,在晶体管的沟道区上形成氧化物层; (c)去除所述氧化物层,以及形成所述晶体管的沟槽形式,以使所述凹部定位成低于所述衬底的表面; (d)在所述凹部中形成栅电极; 和(e)在整个表面上进行第二离子注入,进行热处理以形成源/漏区。

    • Example embodiments relate to a semiconductor memory device and a method of fabricating the same. Other example embodiments relate to a phase change memory device and a method of fabricating the same. There are provided a phase change memory device and a method of fabricating the same for improving or maximizing a production yield. The method comprises: after first removing a first hard mask layer used to form a contact pad electrically connected to a semiconductor substrate, forming a lower electrode to be electrically connected to the contact pad through a first contact hole in a first interlayer insulating layer formed on the contact pad and to have a thickness equal or similar to a thickness of the first interlayer insulating layer; and forming a phase change layer and an upper electrode on the lower electrode. Because change of the resistance value of the lower electrode is reduced or prevented, which has been caused due to a non-uniform thickness of a conventional first hard mask layer, a production yield may be improved.
    • 示例性实施例涉及半导体存储器件及其制造方法。 其他示例性实施例涉及相变存储器件及其制造方法。 提供了一种相变存储器件及其制造方法,用于改善或最大化产量。 该方法包括:在首先去除用于形成与半导体衬底电连接的接触焊盘的第一硬掩模层之后,通过形成在第一层间绝缘层上的第一层间绝缘层中的第一接触孔形成下电极以与接触焊盘电连接 所述接触焊盘的厚度等于或类似于所述第一层间绝缘层的厚度; 并在下电极上形成相变层和上电极。 由于由于常规的第一硬掩模层的厚度不均匀而导致的下部电极的电阻值的变化被降低或防止,所以可以提高生产率。
