    摘要: A method for forming a planarized thin film dielectric film on a surface of a common circuit base upon which one or more integrated circuits are to be attached. The common circuit base includes raised features formed over its surface such that the raised features define a trench area between them. The method includes the steps of forming a first layer of the dielectric film over the common circuit base and over the raised features and the trench, then patterning the newly formed layer to remove portions of the layer formed over the raised features and expose the raised features. After the layer is patterned, formation of the dielectric film is completed by forming a second layer of the dielectric film over the patterned first layer. Additional film deposition and film patterning steps are performed to complete the layout of a thin film interconnect structure over said common circuit base, and an integrated circuit die is attached to the common circuit base and electrically connecting to the thin film interconnect structure. In a preferred embodiment, the first and second layers of the dielectric film are both formed from a photo-definable material and the patterning step includes exposing the first layer to light through a patterned mask corresponding to the raised features and developing the exposed layer with a developing solution to etch away portions of the first layer formed over the raised features.

    摘要: A method for testing for open circuits on a common circuit base having pads for making electrical contact to the common circuit base on both the top and bottom of the circuit base. The common circuit base includes a thin film metal interconnect structure formed on its upper surface and the thin film interconnect structure including an upper dielectric layer deposited over a thin film metalization layer that has contact openings etched through the dielectric layer at selected locations for the formation of contact pads. The method includes the steps of (1) forming a seed layer over the upper dielectric layer and over the contact openings; (2) forming a photoresist layer over the seed layer and patterning the photoresist layer to expose selected portions of the seed layer such that the selected portions correspond generally to the contact openings; (3) plating a conductive layer over the patterned seed layer to form plated contact pads that are electrically connected to an underlying thin film metalization layer; and (4) inspecting the plated conductive layer for open circuits prior to performing subsequent process steps and/or tests. In different embodiments, such subsequent process steps and/or tests include: stripping the photoresist in areas where the contact pads are not formed to expose the seed layer underlying the photoresist; removing the exposed seed layer and performing an electrical test on the common circuit base to determine if any short circuits exist in the interconnect structure.

    摘要: Highly sensitive devices for detecting nitric oxide and/or other gaseous analytes in gaseous samples are improved by the incorporation of a carbon monoxide scavenger in the interior of the device or in the device packaging. The release of carbon monoxide within the housing of the device by the plastic used in the construction of the housing or by anything within the device that releases carbon monoxide causes a loss in sensitivity due to competition between the carbon monoxide and the nitric oxide for the binding sites on the device sensor. The scavenger corrects this by either catalyzing the oxidation of carbon monoxide to the less competitive carbon dioxide or immobilizing the carbon monoxide by affinity-type or covalent binding. Analogous effects are achieved for analytes other than nitric oxide but that likewise encounter interference from carbon monoxide in binding to sensors.
