WebThe new wafer-level package (WLP) technology uses larger solder balls, typically measuring 300 to 500 µm in diameter. Solder bumped flip chips typically use solder spheres to connect the device directly to the circuit board. The solder bumps are placed on the active side of the device, either directly on I/O pads or routed from them. WebAlmost all the medium-current implanters which deliver beam currents in the range of a few mA incorporate the concept of hybrid scanning by combining a beam scan and a one-axis mechanical wafer scan. Fig. 2.8 shows an example of a modern medium-current implanter from Nissin Corp. for 300mm wafers which can be employed for the 45nm technology …
