Abstract:
In described examples, an electronic system includes an electronic body (301) with terminal pads (310) and at least one capacitor embedded in the electronic body. The capacitor includes: an insulating and adhesive first polymeric film (302) covering the body surface except the terminal pads; a sheet (320) of high-density capacitive elements, the first capacitor terminal being a metal foil (321) attached to the first polymeric film (302), the second terminal being a conductive polymeric compound (324), and the insulator being a dielectric skin (323). Sheet (320) has sets of via-holes, including: a first set of holes reaching the metal foil (321), a second set of holes reaching the terminals (310), and a third set of holes reaching the conductive polymeric compound (324). An insulating second polymeric film (303) lines the sidewalls of the holes and planarizes the sheet surface. Metal fills the via-holes between the polymeric sidewalls and forms conductive traces and attachment pads on the system surface.
Abstract:
Processes for sealing porous low k dielectric film generally comprises exposing the porous surface of the porous low k dielectric film to ultraviolet (UV) radiation at intensities, times, wavelengths and in an atmosphere effective to seal the porous dielectric surface by means of carbonization, oxidation, and/or film densification. The surface of the surface of the porous low k material is sealed to a depth less than or equal to about 20 nanometers, wherein the surface is substantially free of pores after the UV exposure.

Abstract:
A method and an apparatus for depositing a dielectric layer to fill in a gap between adjacent metal lines. In preferred embodiments of the method, a first dielectric layer is deposited over the lines and subsequently etched using both chemical and physical etchback steps. After the etchback steps are completed, a second dielectric layer is deposited over the first dielectric layer to fill in the gap.
Abstract:
A first layer of a first material is formed on a surface of a semiconductor substrate over circuit features to a predetermined thickness. A trace layer of a second material is formed on the first layer. Then a second layer of material is formed on the trace layer. The second layer is then planarized. During planarization, the trace layer above the circuit features will be reached as the second layer is removed. Upon reaching the trace layer, planarization will terminate.
Abstract:
A method of applying spin-on glass (SOG) on a substrate over low-melting point, non-refractory materials such as aluminium (1a, 1b) is disclosed. In the method a layer of applied spin-on glass (4) is subjected to disconnection and outgassing of water and reaction by-products, and then capped with a protective dielectric layer resistant to moisture diffusion (5).
Abstract:
A method of applying a spin-on glass layer to a substrate is disclosed characterized in that the spin-on glass is applied as a plurality of contiguous thin layers that together form a composite layer. Each thin layer is cured prior to the application of the next layer at a temperature of at least about 300 °C, preferably 350 °C, for a time sufficient to permit catalyst connection and substantially eliminate volatile residual solvents contained therein. In this way cracking in organic SOGs can be substantially eliminated, and beneficial results can also be achieved with quasi-organic SOGs.
Abstract:
Systems and methods for providing 3D wafer assembly with known-good- dies are provided. An example method compiles an index of dies on a semiconductor wafer and removes the defective dies to provide a wafer with dies that are all operational. Defective dies on multiple wafers may be removed in parallel, and resulting wafers with all good dies stacked in 3D wafer assembly. In an implementation, the spaces left by removed defective dies may be filled at least in part with operational dies or with a fill material. Defective dies may be replaced either before or after wafer-to-wafer assembly to eliminate production of defective stacked devices, or the spaces may be left empty. A bottom device wafer may also have its defective dies removed or replaced, resulting in wafer-to-wafer assembly that provides 3D stacks with no defective dies.
