Semiconductor probe and alignment system |
摘要 |
A semiconductor probe and alignment system are disclosed. The semiconductor probe includes a silicon-based substrate and membrane on which a plurality of pyramid shaped contactors are formed. Each of the contactors includes a metalized tip for contacting bonding pads on a semiconductor die. The area of the probe surrounding each contactor is thinned to form a membrane to provide flexibility and thus compliance to assure contact between each contactor and its respective bonding pad. In the alignment system, a guide wall formed from a photo-imageable material is created around at least a portion of each bonding pad to provide alignment for guiding the contactors on the probe onto the bonding pads.
