    摘要: For a semiconductor wafer substrate having an inter layer dielectric, a through-silicon via may be formed in the substrate by first depositing an etch stop film on top of the inter layer dielectric, followed by etching an opening through the etch stop film, the interlayer dielectric, and into the substrate. A dielectric liner is then deposited over the etch stop film and into the opening. For some embodiments, the dielectric liner may be etched away except for those portions adhering to the sidewall of the opening. Then a conductive material may be deposited into the opening and on the etch stop film. The excess conductive material may then be removed, and for some embodiments the etch stop film may also be removed.

    摘要: A semiconductor component (such as a semiconductor wafer or semiconductor die) includes a substrate having a front side and a back side. The semiconductor die/wafer also includes a stress balance layer on the back side of the substrate. An active layer deposited on the front side of the substrate creates an unbalanced stress in the semiconductor wafer/die. The stress balance layer balances stress in the semiconductor wafer/die. The stress in the stress balance layer approximately equals the stress in the active layer. Balancing stress in the semiconductor component prevents warpage of the semiconductor wafer/die.

    摘要: A semiconductor die has through silicon vias arranged to reduce warpage. The through silicon vias adjust the coefficient of thermal expansion of the semiconductor die, permit substrate deformation, and also relieve residual stress. The through silicon vias may be located in the edges and/or corners of the semiconductor die. The through silicon vias are stress relief vias that can be supplemented with round corner vias to reducing warpage of the semiconductor die.

    摘要: Glass preforms are cleaned by contacting each preform (11) with supercritical carbon dioxide which dissolves residual index-matching oil on the preform. The liquefied carbon dioxide is then converted to gaseous carbon dioxide which conveniently separates the index-matching oil so that it can be recovered and reused. The gaseous carbon dioxide is likewise recycled for use in cleaning other preforms, and so there is substantially no waste.
