Abstract: The distance between a discrete or passive electrical component and an electrical semiconductor device and substrate or carrier is minimized by shortening the lead length connections of the passive component. One or more passive electronic components are mounted within the body of a carrier or board by creating a cavity in the substrate or carrier that is directly below a semiconductor device. The passive component is electrically connected to the substrate and device using solder bump technology resulting in much shorter lead length connections to and from the passive component.

Abstract: According to the present invention, when a wiring layer using copper is formed, an interlayer insulation film is formed on a semiconductor substrate having a conductive portion of an element. A contact hole, which is connected to at least the conductive portion, is formed in the interlayer insulation film. A wiring groove is formed in the surface of the interlayer insulation film including a region where the contact hole is formed. A barrier metal having a tungsten carbide film on its surface is formed on the surface of the interlayer insulation film and in the wiring groove and contact hole in contact with the conductive portion. A copper film is then formed on the barrier metal in contact with the tungsten carbide film. After that, the contact hole and wiring groove are completely filled with the copper film by heat treatment. An excess portion is removed from the copper film except in the contact hole and wiring groove thereby to form a copper buried wiring layer.

Abstract: The present invention provides a structure for a semiconductor device, capable of eliminating the generation of defective products due to poor connection. In the present semiconductor device, an n-type high concentration diffusion layer 2 is selectively formed on the P-type silicon substrate 1, and on the diffusion layer 2, a silicon oxide film 3 is formed as a first interlayer insulating film 3. A silicon plug 4 is disposed on the n-type high concentration diffusion layer 2. On the top end surface of the polysilicon plug 4, a silicide pad 5 is formed in a self-aligning manner such that the width of the silicide pad 5 is larger than that of the polysilicon plug 4. A second interlayer insulating film is formed so as to cover the first interlayer insulating film 3 and the silicide pad 5, and a tungsten plug 7 is disposed on the silicide pad 5. On the second interlayer insulating film, wiring 8, made of an aluminum-copper alloy and connected to the tungsten plug, is formed.

Abstract: A typical integrated circuit interconnects millions of microscopic transistors and resistors with aluminum wires buried in silicon-dioxide insulation. Yet, aluminum wires and silicon-dioxide insulation are a less attractive combination than gold, silver, or copper wires combined with polymer-based insulation, which promise both lower electrical resistance and capacitance and thus faster, more efficient circuits. Unfortunately, conventional etch-based techniques are ineffective with gold, silver, or copper, and conventional polymer formation promote reactions with metals that undermine the insulative properties of polymer-based insulations. Accordingly, the inventor devised methods which use a liftoff procedure to avoid etching problems and a non-acid-polymeric precursor and non-oxidizing cure procedure to preserve the insulative properties of the polymeric insulator. The resulting interconnective structures facilitate integrated circuits with better speed and efficiency.
