  • Patent number: 9434076
    Abstract: The present disclosure relates to a wafer transfer robot having a robot blade that can be used to handle substrates that are patterned on both sides without causing warpage of the substrates. In some embodiments, the wafer transfer robot has a robot blade coupled to a transfer arm that varies a position of the robot blade. The robot blade has a wafer reception area that receives a substrate. Two or more spatially distinct contact points are located at positions along a perimeter of the wafer reception area that provide support to opposing edges of the substrate. The two or more contact points are separated by a cavity in the robot blade. The cavity mitigates contact between a backside of the substrate and the robot blade, while providing support to opposing sides of the substrate to prevent warpage of the substrate.

  • Publication number: 20160005642
    Abstract: Among other things, one or more semiconductor arrangements comprising isolation trenches, and techniques for forming such isolation trenches are provided. A substrate comprises a front side surface and a backside surface. One or more devices are formed over the front side surface. A wet etch is performed to form a tapered portion of an isolation trench. A dry etch is performed to form a non-tapered portion of the isolation trench. Because both the wet etch and the dry etch are performed, etching time is reduced compared to merely using the dry etch due to the wet etch having a relatively faster etch rate than the dry etch. In an embodiment, the isolation trench provides isolation for a current leakage path associated with a device or other material formed over the front side surface. In an embodiment, metal is formed within the isolation trench for backside metallization.

  • Publication number: 20150375992
    Abstract: A semiconductor arrangement and methods of formation are provided. The semiconductor arrangement includes a micro-electro mechanical system (MEMS). A via opening is formed through a substrate, first dielectric layer and a first plug of the MEMS. The first plug comprises a first material, where the first material has an etch selectivity different than an etch selectivity of the first dielectric layer. The different etch selectivity of first plug allows the via opening to be formed relatively quickly and with a relatively high aspect ratio and desired a profile, as compared to forming the via opening without using the first plug.

  • Patent number: 9224615
    Abstract: A method of etching a trench in a substrate is provided. The method repeatedly alternates between using a fluorine-based plasma to etch a trench, which has trench sidewalls, into a selected region of the substrate; and using a fluorocarbon plasma to deposit a liner on the trench sidewalls. The liner, when formed and subsequently etched, has an exposed sidewall surface that includes scalloped recesses. The trench, which includes the scalloped recesses, is then bombarded with a molecular beam where the molecules are directed on an axis parallel to the trench sidewalls to reduce the scalloped recesses.

  • Patent number: 9159723
    Abstract: A novel method for manufacturing a semiconductor device and a semiconductor device are provided. The semiconductor device includes a substrate, a trench capacitor, a contact pad, an inter-layer dielectric (ILD) layer and contact elements. The trench capacitor includes a doped region, a first dielectric layer, a bottom electrode, a second dielectric layer and a top electrode, in which the contact pad is positioned on the doped region. The ILD layer has contact windows, and the contact elements are disposed therein. Because of the presence of the contact pad positioned on the doped region, the thickness of the ILD layer over the top electrode is increased but still satisfying the requirement of the maximum depth limit to the contact windows of etching the ILD layer.
