    摘要: Ultra-low capacitance interconnect structures, preferably Through Silicon Via (TSV) interconnects and methods for fabricating said interconnects are disclosed. The fabrication method comprises the steps of providing a substrate having a first main surface, producing at least one hollow trench-like structure therein from the first main surface, said trench-like structure surrounding an inner pillar structure of substrate material, depositing a dielectric liner which pinches off said hollow trench-like structure at the first main surface such that an airgap is created in the center of hollow trench-like structure and further creating a TSV hole and filling it at least partly with conductive material.

    摘要: The present invention is related to a method for singulating chips from a stack of layers, such as the layers on a wafer or substrate. The stack of layers includes a front end of line (FEOL) layer upon the substrate layer, with the substrate layer having a first surface and a second surface. The FEOL is positioned on top of the first surface, and a back end of line (BEOL) layer is positioned on top of the FEOL. The method includes etching singulating trenches through the BEOL, through the FEOL and at least partially through the substrate layer, depositing a passivation layer on the stack provided with singulating trenches, whereby the sidewalls of the etched singulating trenches are at least partially passivated. Dicing, such as blade dicing, laser dicing or trench etch dicing is performed, releasing the chip from the stack of layers.

    摘要: A method is presented in which an active element, e.g. a semiconductor device, is embedded in a passive circuitry formed on a low-cost substrate, having good dielectric properties. After forming the active element on a first substrate, the active elements are singulated and transferred to a second substrate. The active element is bonded to this second substrate and the portion of the first substrate, on which this active element is created, is removed selectively to the active element and the low-cost substrate. On this second substrate passive circuitry may be present or it can be formed after the attachment of the active element. The passive circuitry is interconnected to the active element or other components or dies present on the low-cost substrate.

    摘要: A method for detecting embedded voids present in a structure formed in or on a semiconductor substrate is described. The method includes performing a processing step P1 for forming the structure; measuring the mass M1 of the substrate; performing thermal treatment; measuring the mass M2 of the substrate; calculating the mass difference between the mass of the substrate measured before and after the performed thermal treatment; and deducing the presence of embedded voids in the structure by comparing the mass difference with a pre-determined value.
