    摘要: A method is described for forming an element of a microelectronic circuit. A sacrificial layer is formed on an upper surface of a support layer. The sacrificial layer is extremely thin and uniform. A height-defining layer is then formed on the sacrificial layer, whereafter the sacrificial layer is etched away so that a well-defined gap is left between an upper surface of the support layer and a lower surface of the height-defining layer. A monocrystalline semiconductor material is then selectively grown from a nucleation silicon site through the gap. The monocrystalline semiconductor material forms a monocrystalline layer having a thickness corresponding to the thickness of the original sacrificial layer.

    摘要: A n-gate transistor, and method of forming such, including source/drain regions connected by a channel region and a gate electrode coupled to the channel region. The channel region has many angled edges protruding into the gate electrode. The many angled edges are to act as electrically conducting channel conduits between source/drain regions.

    摘要: A method is provided for forming sub-micron-size structures over a substrate. A width-defining step is formed over the substrate. A width-defining layer is formed over an edge of the width-defining step. The width-defining layer is etched back to leave a spacer adjacent the width-defining step. A length-defining step is formed over the substrate. A length-defining layer is formed over an edge of the length-defining step. The length-defining layer is etched back to leave a spacer adjacent a first edge of the length-defining step and across a first portion of the spacer left by the width-defining layer. The length-defining step is then removed. The spacer left by the width-defining layer is then etched with the spacer left by the length-defining layer serving as a mask, to form the structure.
