  • Method of making gold-cobalt contact for silicon devices
    Patent number: 4065588
    Abstract: A contact for a silicon device comprises a layer of gold on the silicon, and a layer of cobalt on the gold layer. The contact is made by depositing gold on the silicon, depositing cobalt on the gold and heating the structure at a temperature between about 300.degree. and about 370.degree. C in a reducing gas atmosphere.

  • Method of electrolessly depositing nickel-phosphorus alloys
    Patent number: 3953624
    Abstract: Nickel-phosphorus alloys are electrolessly deposited such that initial deposition takes place at a relatively rapid rate and at a particular acid pH, then when the nickel content of the bath has dropped to a low level, pH drops rather abruptly and the final material deposited has a high phosphorus content relative to the layers initially deposited. In this method the phosphorus content of the surface layers is closely controlled to maintain uniform behavior of the plating in subsequent soldering, wire-bonding and welding operations.
