A clip for a semiconductor device package may include two or more separate electrically conductive fingers electrically connected to each other by one or more electrically conductive bridges. A first end of at least finger is adapted for electrical contact with a lead frame. The bridges are adapted to provide electrical connection to a top semiconductor region of a semiconductor device and may also to provide heat dissipation path when a top surface of the fingers is exposed. A semiconductor device package may include the clip along with a semiconductor device and a lead frame. The semiconductor device may have a first and semiconductor regions on top and bottom surfaces respectively. The clip may be electrically connected to the top semiconductor region at the bridges and electrically connected to the lead frame at a first end of at least one of the fingers.

A solder-top enhanced semiconductor device is proposed for packaging. The solder-top device includes a device die with a top metal layer patterned into contact zones and contact enhancement zones. At least one contact zone is electrically connected to at least one contact enhancement zone. Atop each contact enhancement zone is a solder layer for an increased composite thickness thus lowered parasitic impedance. Where the top metal material can not form a uniform good electrical bond with the solder material, the device die further includes an intermediary layer sandwiched between and forming a uniform electrical bond with the top metal layer and the solder layer. A method for making the solder-top device includes lithographically patterning the top metal layer into the contact zones and the contact enhancement zones; then forming a solder layer atop each of the contact enhancement zones using a stencil process for an increased composite thickness.

摘要:
The dispenser draws a concentrate fluid from a liquid container into an input fluid. There is an elongated channel having an input for the input fluid and dispensing nozzle at an exit end for dispensing the concentrate fluid in a diluted form. A transverse intersecting channel is intermediate the input end and the exit end. An insert is moveable in the transverse intersecting channel, apertures of the moveable insert being alignable with apertures in the transverse intersecting channel and the liquid container. The channels from the liquid container will have a plurality of various sized apertures to provide for the flow of differing amounts of concentrate fluid into the input fluid. By adjusting the moveable insert in the transverse intersecting channel and/or the input fluid flow rate the concentration of concentrate fluid in the input fluid is changed.
