    摘要: A method of making a semiconductor device includes providing a first element formed of a first substantially electrically conductive material and having an upper surface. A second element adjacent to the first element is provided. The second element is formed of a first substantially non-electrically conductive material. An upper surface of the second element slopes downwardly toward the upper surface of the first element. A first layer of a second substantially non-electrically conductive material is disposed over the upper surface of the first element and the upper surface of the second element. The first layer has a thickness in the vertical direction that is greater in an area over the downward slope of the second element than in an area over the first element. An etching process is performed such that the layer is perforated above the upper surface of the first element and imperforated in the vertically thicker area above the downwardly sloping upper surface of the second element.

    摘要: A method for detecting an end point of an etching step conducted in an etching chamber. A target emission intensity level is selected for the etching step, and the etching step is performed in the etching chamber. A raw emission intensity level is sensed from the etching chamber during the etching step with an emission intensity level detector. The raw emission intensity level sensed from the etching chamber by the emission detector is modified with an emission intensity level modifier. The raw emission intensity level sensed with the emission intensity level detector from the etching chamber during the etching step is adjusted to the target emission intensity level by adjusting the emission intensity level modifier. The etching process is stopped upon occurrence of a predetermined spectral event sensed by the emission intensity level detector.

    摘要: A low-K value dielectric protection spacer for patterning through substrate vias (TSVs) through a low-K value wiring layer. A method for forming a low-K value dielectric protection spacer includes etching a via opening through a low-K value dielectric interconnect layer. A protective layer is deposited in the via opening and on the low-K value dielectric interconnect layer. At least a portion of the protective layer is etched from the bottom of the via opening and from a horizontal surface of the low-K value dielectric interconnect layer. The etching leaving a protective sidewall spacer on a sidewall of the via opening. A through substrate via is etched through the bottom of the via opening and through the semiconductor substrate. The through substrate via is filled with a conductive material.

    摘要: The cost associated with alignment in a stacked IC device can be reduced by aligning multiple die instead of a single die during the alignment step. In one embodiment, the alignment structures are placed in the scribe line instead of within the die itself. Aligning four die instead of one eliminates the need for as many alignment indicators and thus more silicon on the wafer can be used for active areas. In addition, this method allows for yield improvement through binning of dies having the same yield configuration.

    摘要: A voltage-switchable dielectric layer may be employed on a die for electrostatic discharge (ESD) protection. The voltage-switchable dielectric layer functions as a dielectric layer between terminals of the die during normal operation of the die. When ESD events occur at the terminals of the die, a high voltage between the terminals switches the voltage-switchable dielectric layer into a conducting layer to allow current to discharge to a ground terminal of the die without the current passing through circuitry of the die. Thus, damage to the circuitry of the die is reduced or prevented during ESD events on dies with the voltage-switchable dielectric layer. The voltage-switchable dielectric layer may be deposited on the back side of a die for protection during stacking with a second die to form a stacked IC.

    摘要: A system and method prevent corrosive elements (or at least the oxidizing agent) from making contact with metal connections at the interface between two layers of a stacked IC device. When layers are positioned in proximity to each other, a cavity is formed at the boundary of the planar surfaces of the layers. This cavity is bounded by a peripheral seal between the layers. In one embodiment, a vacuum is created within the cavity thereby reducing the corrosive atmosphere within the cavity. In another embodiment, the cavity is filled with an inert gas, such as argon. Once the cavity has oxidizing elements reduced, the peripheral seal can be encapsulated to prevent seepage of contaminants into the cavity.
