  • Patent number: 7217645
    Abstract: Solder is connected to the electrodes of the circuit board by using a temperature profile with a constant fusion temperature, a connection interface strength evaluation test is carried out on the soldered joints to obtain an appropriate reflow range free of decreases in the strength at the connection interface. On the basis of the appropriate reflow range obtained and using as the basis the chemical compound thickness which is determined uniquely by heat load, an appropriate reflow range in an optional temperature profile with one temperature peak is obtained. By carrying out connection in this appropriate reflow range, soldered joints can be obtained without decreases in the connection interface strength in the large-scale production stage.

  • Patent number: 7217658
    Abstract: High density plasma chemical vapor deposition and etch back processes fill high aspect ratio gaps without liner erosion or further underlying structure attack. The characteristics of the deposition process are modulated such that the deposition component of the process initially dominates the sputter component of the process. For example, reactive gasses are introduced in a gradient fashion into the HDP reactor and introduction of bias power onto the substrate is delayed and gradually increased or reactor pressure is decreased. In the case of a multi-step etch enhanced gap fill process, the invention may involve gradually modulating deposition and etch components during transitions between process steps. By carefully controlling the transitions between process steps, including the introduction of reactive species into the HDP reactor and the application of source and bias power onto the substrate, structure erosion is prevented.

  • Patent number: 7217683
    Abstract: Nanoscale chemicals based on polyhedral oligomeric silsesquioxanes (POSS) and polyhedral oligomeric silicates (POS) are taught as lubricants, mold release agents, and as additives to control the viscosity, lubrication, wear, and thermal properties of conventional lubricous materials. The precisely defined nanoscopic dimensions of POSS materials enable viscosity, miscibility, and thermal properties to be (increased) or reduced (decreased) as desired. A key feature to the successful tailoring of properties is the inherent thermal and chemical stability of the POSS/POS nanostructure and the ability to control its topology and chemical potential to match that of surfaces and other materials.
