    Abstract: A method for bonding at low or room temperature includes steps of surface cleaning and activation by cleaning or etching. The method may also include removing by-products of interface polymerization to prevent a reverse polymerization reaction to allow room temperature chemical bonding of materials such as silicon, silicon nitride and SiO2. The surfaces to be bonded are polished to a high degree of smoothness and planarity. VSE may use reactive ion etching or wet etching to slightly etch the surfaces being bonded. The surface roughness and planarity are not degraded and may be enhanced by the VSE process. The etched surfaces may be rinsed in solutions such as ammonium hydroxide or ammonium fluoride to promote the formation of desired bonding species on the surfaces.

  • Publication number: 20140197375
    Abstract: A tensile strain state in semiconductor components is adjusted. A pretensioned (tensile strain) layer is applied to a substrate (FIG. 1, (A)). Bridge structures (FIG. 1, (B)) are introduced in the layers by lithography and etching. The bridges are connected to the layer on both sides and are thus continuous. The geometric shape of the bridges, formed with a cross-section modulation, is determined by the windows (FIG. 1 (C)) in the layer. When the substrate is etched selectively, the bridge is undercut through the windows. The geometric structuring of the cross-section (FIG. 1, (D)) causes a redistribution of the originally homogeneous strain when the bridges are detached from the substrate, with the larger cross-sections relaxing at the expense of the smaller cross-sections, where the pretension is increased. Only a multiplication of stresses (or strain) originally present in the sample is possible, with the multiplication factor determined by lengths, widths and depths, and/or the relationships thereof.

  • Patent number: 8754338
    Abstract: An electronics interconnection system is provided with reduced capacitance between a signal line and the surrounding dielectric material. By using a non-homogenous dielectric, the effective dielectric constant of the material is reduced. This reduction results in less power loss from the signal line to the dielectric material, and therefore reduces the number of buffers needed on the signal line. This increases the speed of the signal, and reduces the power consumed by the interconnection system. The fabrication techniques provided are advantageous because they can be preformed using today's standard IC fabrication techniques.

  • Patent number: 8754504
    Abstract: A thinning method of a wafer is provided. The method includes the following steps. First, a wafer having a first surface, a second surface, and a side surface is provided, and the side surface is connected between the first surface and the second surface. At least one semiconductor device is formed on the first surface. Then, an anisotropy etching process is performed to the second surface with a mask to remove portions of the wafer while remaining the side surface thereby forming a number of grooves in the second surface and at least one reinforcing wall between the grooves. As a result, a thinned wafer is obtained.
