摘要:
Ultrashort laser pulses are used to induce photodisruptive breakdown in vasculature in an animal to controllably produce hemorrhage, thrombosis or breach of the blood-brain barrier in individual, specifically-targeted blood vessels. Damage is limited to the targeted vessels such that neighboring vessels exhibit no signs of vascular damage, including vessels directly above and directly below the targeted vessel. Ultrashort laser pulses of lower energy are also used to observe and quantify the baseline and altered states of blood flow. Observation and measurement may be performed by TPLSM, OCT or other known techniques, providing a real-time, in vivo model for the dynamics and effects of vascular injury.

摘要:
A semiconductor package 10 comprising: terminals 14 electrically connected to a semiconductor device 11; and a resin 15 for sealing a part of the terminals 14 and the device 11; wherein an electrolytic plating layer 19 of Ag, Sn, or Ni is formed on each of bottom surfaces 17 of the terminals 14 partly projecting from the resin 15; an electroless plating layer 22 of Ni, Sn, Ag, Ag/Au, Ni/Au, Ni/Ag, Ni/Pd/Au, or Ni/Pd/Ag is formed thereon; and an electroless plating layer 22 comprising the same material as the electroless plating layer 22 previously formed on the bottom surface 17 of the protruding terminal 14, is formed on each lateral surfaces 20 of the protruding terminals 14. This configuration enables a lead frame material 32 to be etched from its bottom surface to separate the terminals 14 from each other, thereby preventing corrosion due to oxidation of the lateral surfaces (standoff sides) of the terminals 14 exposed by the etching, and further reducing a total manufacturing cost.
