    Abstract: The present disclosure provides, in various aspects, a method of forming a semiconductor device and accordingly formed semiconductor devices. In accordance with some illustrative embodiments herein, a fin is provided in an upper surface of a substrate, the fin having a height dimension and an initial width dimension. After forming a mask on the fin, wherein the mask only partially covers an upper surface of the fin, the fin is exposed to an etch process for removing material in accordance with the mask such that a channel portion connecting end portions of the fin is formed. Herein, a width dimension of the channel portion is smaller than a width dimension of the end portions. In accordance with some illustrative embodiments of the present disclosure, the channel portion may substantially have a cross-section of one of a triangular shape and a double-sigma shape.

    Abstract: The present disclosure provides an improved method for forming a thin semiconductor alloy layer on top of a semiconductor layer. The proposed method relies on an implantation of appropriate impurity species before performing deposition of the semiconductor alloy film. The implanted species cause the semiconductor alloy layer to be less unstable to wet and dry etches performed on the device surface after deposition. Thus, the thickness uniformity of the semiconductor alloy film may be substantially increased if the film is deposited after performing the implantation. On the other hand, some implanted impurities have been found to decrease the growth rate of the semiconductor alloy layer. Thus, by selectively implanting appropriate impurities in predetermined portions of a wafer, a single deposition step may be used in order to form a semiconductor alloy layer with a thickness which may be locally adjusted at will.

    Abstract translation: 本公开提供了一种用于在半导体层的顶部上形成薄半导体合金层的改进方法。 所提出的方法依赖于在进行半导体合金膜的沉积之前植入适当的杂质物质。 植入的物质导致半导体合金层在沉积后在器件表面上进行的湿法干蚀刻不太稳定。 因此,如果在进行植入之后沉积膜,则半导体合金膜的厚度均匀性可以显着增加。 另一方面,已经发现一些植入的杂质降低了半导体合金层的生长速率。 因此,通过在晶片的预定部分中选择性地注入适当的杂质,可以使用单个沉积步骤以形成具有可以随意局部调整的厚度的半导体合金层。
