    摘要： A dielectric layer in a wiring substrate having a sloped sidewall. A photomask used to pattern the dielectric layer includes optical proximity features. The size and spacing of the optical proximity features are generally less than the resolution limit of the exposure tool used and do not print out on the layer. The optical proximity features provide a transition region between fully exposed material and un-exposed material, which results in a sloped sidewall of the photo-sensitive material after development. The sloped sidewall provides a more reliable thin film metal layer to contact through vias, and may be used to conserve wiring board area by allowing smaller via spacing.

    摘要： A liquid chemical formulation suitable for making a thin solid polycarbonate film contains polycarbonate material and a liquid typically capable of dissolving the polycarbonate material to a concentration of at least 1%. The polycarbonate material may consist of homopolycarbonate or/and copolycarbonate. Examples of the liquid include pyridine, a ring-substituted pyridine derivative, pyrrole, a ring-substituted pyrrole derivative, pyrrolidine, a pyrrolidine derativive, chlorobenzene, and cyclohexanone. A liquid film (36A) of the formulation is formed over a substructure (30) and processed to remove the liquid. The resultant solid polycarbonate film can later serve as a track layer through which charged particles (70) are passed to form charged-particle tracks (72). Apertures (74) are created through the track layer by a process that entails etching along the tracks. The aperture-containing polycarbonate track layer is typically used in fabricating a gated electron-emitting device.

    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.
