A method and apparatus for ultra thin wafer backside processing are disclosed. The apparatus includes an outer ring holding a high temperature grinding and/or dicing tape to form a support structure. An ultra thin wafer or diced wafer is adhered to the tape within the ring for wafer backside processing. The wafer backside processing includes ion implantation, annealing, etching, sputtering and evaporation while the wafer is in the support structure. Alternative uses of the support structure are also disclosed including the fabrication of dies having metalized side walls.

A gold/silicon eutectic die bonding method is disclosed. The method includes the steps of 1) vacuum evaporating a layer of titanium to a silicon wafer backside, the titanium layer having a thickness less than 200 Å, 2) immediately vacuum evaporating a layer of gold onto the titanium layer, the gold layer having a thickness in the range of 0.5 to 1.5 microns, 3) dicing the wafer, and 4) mounting the die onto a substrate at a eutectic temperature to form a gold/silicon eutectic alloy bond.
摘要:
A sensor assembly for monitoring physiological characteristics interfaces to a subject's ear. The sensor assembly has a projection that projects into the subject's concha. The projection may have a notch to accommodate the subject's anti-tragus. A clip connected to the projection holds a sensor against the subject's lobule. The sensor may comprise a pulse-oximetry-type sensor.
摘要:
A wafer level method for metallizing source, gate and drain contact areas of a semiconductor die includes the steps of (a) plating Ni onto the source, gate and drain contact areas of the semiconductor die, and (b) plating Au onto the source, gate and drain contact areas of the semiconductor die after completing step (a). A semiconductor package having plate interconnections between leadframe leads and the metalized passivation areas is also disclosed.
摘要:
A semiconductor package is disclosed. The package includes a leadframe having drain, source and gate leads, a semiconductor die coupled to the leadframe, the semiconductor die having metalized source and gate areas separated by a passivation area, a patterned source connection coupling the source lead to the semiconductor die metalized source area, a patterned gate connection coupling the gate lead to the semiconductor die metalized gate area, a semiconductor die drain area coupled to the drain lead and an encapsulant covering at least a portion of the semiconductor die and drain, source and gate leads.
摘要:
An elongate display track device has a plurality of track segments frangibly connected end-to-end to one another forming a continuous track for receiving a row of articles for sliding movement therealong. There are a front track segment defining an a-keyway, and a rear track segment defining a b-keyway. At least one first intermediate track segment has an a-key on one end and a b-key on the other end. The a-keys are mateable only with a-keyways and b-keys are mateable only with b-keyways. At least one second intermediate track segment has an b-keyway on one end a b-key on the other end. At least one third intermediate track segment has an b-keyway on one end an a-keyway on the other end. The track device is separated at the a-keys and a-keyways to shorten the track length and separated at the b-keys and b-keyways to lengthen the track to fit a shelf.
