Abstract: Elongated fins of a first semiconductor material are insulated from and formed over an underlying substrate layer. Elongated gates of a second semiconductor material are then formed to cross over the elongated fins at channel regions, and the gate side walls are covered by sidewall spacers. A protective material is provided to cover the underlying substrate layer and define sidewall spacers on side walls of the elongated fins between the elongated gates. The first semiconductor material and insulating material of the elongated fins located between the protective material sidewall spacers (but not under the elongated gates) is removed to form trenches aligned with the channel regions. Additional semiconductor material is then epitaxially grown inside each trench between the elongated gates to form source-drain regions adjacent the channel regions formed by the elongated fins of the first semiconductor material located under the elongated gates.

Abstract: A brush-cleaning apparatus is disclosed for use in cleaning a semiconductor wafer after polishing. Embodiments of the brush-cleaning apparatus implemented with a multi-branch chemical dispensing unit are applied beneficially to clean semiconductor wafers, post-polish, using a hybrid cleaning method. An exemplary hybrid cleaning method employs a two-chemical sequence in which first and second chemical treatment modules are separate from one another, and are followed by a pH-neutralizing-rinse that occurs in a treatment module separate from the first and second chemical treatment modules. Implementation of such hybrid methods is facilitated by the multi-branch chemical dispensing unit, which provides separate chemical lines to different chemical treatment modules, and dispenses chemical to at least four different areas of each wafer during single-wafer processing in an upright orientation. The multi-branch chemical dispensing unit provides a flexible, modular building block for constructing various equipment configurations that use multiple chemical treatments and/or pH neutralization steps.

Abstract: One or more embodiments are directed to semiconductor packages that are assembled using a sacrificial material, that when removed, separates the assembled packages into individual packages. The sacrificial material may be removed by a blanket technique such that a mask, pattern, or alignment step is not needed. In one embodiment the sacrificial material is formed on the lead frame on a connecting bar of a lead frame between adjacent leads. After the molding step, the connecting bar is etched away exposing a surface of the sacrificial material. The sacrificial material is removed, thereby separating the assembled packages into individual packages.

Abstract: A shallow trench is formed to extend into a handle substrate of a semiconductor-on-insulator (SOI) layer. A dielectric liner stack of a dielectric metal oxide layer and a silicon nitride layer is formed in the shallow trench, followed by deposition of a shallow trench isolation fill portion. The dielectric liner stack is removed from above a top surface of a top semiconductor portion, followed by removal of a silicon nitride pad layer and an upper vertical portion of the dielectric metal oxide layer. A divot laterally surrounding a stack of a top semiconductor portion and a buried insulator portion is filled with a silicon nitride portion. Gate structures and source/drain structures are subsequently formed. The silicon nitride portion or the dielectric metal oxide layer functions as a stopping layer during formation of source/drain contact via holes, thereby preventing electrical shorts between source/drain contact via structures and the handle substrate.

Abstract: An integrated transistor in the form of a nanoscale electromechanical switch eliminates CMOS current leakage and increases switching speed. The nanoscale electromechanical switch features a semiconducting cantilever that extends from a portion of the substrate into a cavity. The cantilever flexes in response to a voltage applied to the transistor gate thus forming a conducting channel underneath the gate. When the device is off, the cantilever returns to its resting position. Such motion of the cantilever breaks the circuit, restoring a void underneath the gate that blocks current flow, thus solving the problem of leakage. Fabrication of the nano-electromechanical switch is compatible with existing CMOS transistor fabrication processes. By doping the cantilever and using a back bias and a metallic cantilever tip, sensitivity of the switch can be further improved. A footprint of the nano-electromechanical switch can be as small as 0.1×0.1 μm2.
