Abstract:
A probe platform for electrically probing semiconductor wafers comprising:a plurality of tiles attached to a platform and configured in a matrix having an X-axis and an orthogonal Y-axis, wherein each of the tiles may move independently parallel to the X-axis and the Y-axis, each tile attached to a plurality of probes to permit semiconductor wafer testing;a plurality of first transmission shafts attached to the plurality of tiles parallel to the X-axis, each of the first transmission shafts having a first control knob for imparting rotational power to the first transmission shaft, each of the first transmission shafts capable of sliding parallel to the X-axis into a plurality of ball detent positions, wherein each of the ball detent positions determines which tile is engaged and can be manipulated parallel to the X-axis; anda plurality of second transmission shafts attached to the plurality of tiles parallel to the Y-axis, each of the second transmission shafts having a second control knob for imparting rotational power to the second transmission shaft, each of the second transmission shafts capable of sliding parallel to the Y-axis into a plurality of ball detent positions, wherein each of the ball detent positions determines which tile is engaged and can be manipulated parallel to the Y-axis.
