  • Patent number: 7687304
    Abstract: A material for forming a conductive structure for a micromechanical current-driven device is described, which is an alloy containing about 0.025% manganese and the remainder nickel. Data shows that the alloy possesses advantageous mechanical and electrical properties. In particular, the sheet resistance of the alloy is actually lower and more stable than the sheet resistance of the pure metal. Accordingly, when used for conductive leads in a photonic device, the leads using the NiMn alloy may provide current to heat the photonic device while generating less heat within the leads themselves, and a more stable output.

  • Patent number: 7618845
    Abstract: A QFN integrated circuit is mounted on a leadframe having multiple lead lands and resin material encapsulates the integrated circuit leaving the lead lands exposed. Subsequently a sawing operation divides the lead lands into multiple leads, and the leadframe and resin material are partitioned to form packages. The pitch of the resultant leads is not limited by the pitch of the lead lands of the leadframe, so the leadframe can be of the relatively cheap generic leadframe variety, in which the pitch of the lead lands is higher than the desired pitch of the leads of the completed package. The sawing operation may further include reshaping the diepad area of the leadframe to produce heat sink fins, for improved heat dissipation. The proposed process is suitable both to produce packages including only a single integrated circuit, and also to produce multi-chip modules.
