摘要:
To improve the bonding layer for connecting wires to semiconductor chips with contact fingers, or contact strips, on the carrier, the bonding layer is formed as spongy, microporous structure, applied to discrete positions of the contact strips by screen printing, and secured to the metallic connecting strip by a diffusion zone. Preferably, the bonding layer comprises a metal of gold, palladium, silver, aluminum and copper, or an alloy of at least two of these metals, or a base alloy of one of those metals, for example gold applied as a gold paste having an average grain size of less than 5 micrometers, the layer being between 2 to 30 micrometers thick, preferably 3 to 10 micrometers.

摘要:
An illumination unit having at least one LED as light source, the LED emitting primary radiation in the range from 300 to 485 nm, this radiation being partially or completely converted into longer-wave radiation by phosphors which are exposed to the primary radiation of the LED, in which unit the conversion takes place at least with the aid of a phosphor which emits yellow-orange with a peak emission wavelength at 540 to 620 nm and originates from the class of the Eu-activated sialons, the sialon corresponding to the formula Mp/2Si12−p−qAlp+qOqN16−q:Eu2+, where M=Ca individually or in combination with Mg or Sr, where q=0 to 2.5 and p=0 to 3.
摘要:
A white-emitting luminescence conversion LED uses a chlorosilicate phosphor which, in addition to Ca and Mg, contains a europium doping, and also a garnet phosphor of the rare earths, in particular Y and/or Tb. In this way, it is possible to achieve a high color rendering and a high constancy of the lighting properties under differing temperature conditions.
摘要:
To improve the bonding layer for connecting wires to semiconductor chips with contact fingers, or contact strips, on a substrate carrier, the bonding layer is formed as spongy, microporous structure, applied to discrete positions of the contact strips by screen printing, and secured to the metallic connecting strip by a diffusion zone. Preferably, the bonding layer comprises a metal of gold, palladium, silver, aluminum and copper, or an alloy of at least two of these metals, or a base alloy of one of these metals, for example gold applied as a gold paste having an average grain size of less than 5 micro-meters, the layer being between 2 to 30 micrometers thick, preferably 3 to 10 micrometers. The metal is part of a paste of the metal in an evaporative organic carrier. After screen printing, the carrier is eliminated by heating; subsequent heating converts the metal to a spongy microporous structure bonded to the substrate carrier by a diffusion zone.
