    摘要: A low temperature, high energy soldering composition for joining metals together contains a fluxing agent and high energy metal particles that possess sufficiently high internal energy, suspended in the fluxing agent, such that the melting point of the high energy metal particles is depressed by at least three degrees Celsius below the normal bulk melting temperature of metal. A solder joint is effected by placing the high energy metal particles in contact with one or more of the metal surfaces and heating the high energy metal particles in the presence of a fluxing agent to melt the high energy metal particles and fuse them to the metal surface.

    摘要: A functional ink (200) suitable for use as a dielectric layer (303) in a printed semiconductor device (300) comprises a dielectric carrier (201) and a plurality of dielectric particles (202) sized less than about 1,000 nanometers that are disposed within the dielectric carrier. In a preferred approach the dielectric carrier comprises a dielectric resin and the dielectric particles comprise a ferroelectric material (such as, but not limited to, BaTiO3. So provided, this functional ink can be applied to a substrate (301) of choice through a printing technique of choice to thereby provide a resultant printed semiconductor device, such as a field effect transistor, having a relatively thin dielectric layer comprised of this functional ink.

    摘要: A low temperature-wetting solder paste for forming a tin-base solder connection comprises a mixture of compositionally distinct first and second solder powders. The first solder is formed predominantly of tin, preferably at least 90 weight percent. The second powder is formed of a tin alloy containing indium or bismuth and having a melting temperature less than the first powder. During soldering, the second powder melts during the early stages of the heating cycle to initiate wetting of the faying surfaces and promote dissolution of the first powder, thereby reducing the time and temperature required to form the solder connection.

    摘要: A backlighting device (300, 400, 500, 600) emitting light having a first wavelength includes a first radiation emission device (302), e.g., an electroluminescent lamp, for emitting radiation having a second wavelength. A layer (306) of a plurality of photon emitting particles (308), e.g., free standing quantum dots or phosphorus particles, emits light having the first wavelength in response to the first radiation emission device (302), the first wavelength being larger than the second wavelength. A transparent material (116, 120, 122) overlies the layer of a plurality of photon emitting particles (308), wherein the light having a first wavelength passes through the transparent material (116, 120, 122). Optionally, a filter (402) may be placed over the layer (306) to block the radiation having a second wavelength, and a scattering layer (604) may be placed over the layer (306) to scatter wavelength other than the first wavelength.
