Device and method for scribing a bottom-side of a substrate while viewing the top side

1. A device configured to scribe a bottom side or surface of a sample or substrate while the substrate is oriented with a top side facing up comprising:

a substantially flat and planar table surface configured to receive the substrate, the table surface defining a horizontal plane having an x-axis and a y-axis orthogonal to the x-axis and the x-axis and y-axis lie in the horizontal plane, and further including a plurality of scale lines arranged parallel to y-axis;

a scribe having a tip, the scribe mounted below the horizontal plane, the scribe further disposed to present at least a portion of the tip above the horizontal plane, the scribe further configured to adjust in angle relative to the horizontal plane and a height above the horizontal plane, or to retract below the horizontal plane;

a rail configured in relation to the horizontal plane so that the rail arranges parallel to the y-axis and movable in a direction parallel to the x-axis whereby the sample can he moved relative to the x-axis in corresponding motion with the rail;

a sample guide configured in relation to the horizontal plane so that the sample guide arranges parallel to the x-axis and movable in a direction parallel to the y-axis; and

a scribe stop guide configured in relation to the horizontal plane so that the sample guide arranges parallel to the x-axis and movable in a direction perpendicular to the y-axis, whereby the sample guide moves independent of the scribe stop, the scribe stop further including a locking mechanism to selectively fix the scribe stop at least a first position relative to the y-axis.

2. The device configured to scribe a bottom side or surface of a sample or substrate while the substrate is oriented with a top side facing up of claim 1 further including a hold down coupled to the sample guide.

3. The device configured to scribe a bottom side or surface of a sample or substrate while the substrate is oriented with a top side facing up of claim 1 in which the rail is coupled to the table by a slide.

4. The device configured to scribe a bottom side or surface of a sample or substrate while the substrate is oriented with a top side facing up of claim 1 in which the rail is locked by at least one set screw.

5. The device configured to scribe a bottom side or surface of a sample or substrate while the substrate is oriented with a top side facing up of claim 1 in which the sample guide is orthogonally and slidably coupled to the rail.

6. The device configured to scribe a bottom side or surface of a sample or substrate while the substrate is oriented with a top side facing up of claim 1 in which the scribe further comprises an adjustment lock.

7. A device comprising:

a rectangular table having a first set of parallel sides, and a second set of parallel sides, perpendicular to the first set of parallel sides and including an integral housing body;

a sample guide assembly parallel coupled to the first set of parallel sides so that the sample guide moves across the rectangular table and maintains a parallel orientation to the first set of parallel sides;

a scribe guide slidably coupled at a right angle to the sample guide assembly, and parallel to the second set of parallel sides; and

an adjustable scribe disposed in the rectangular table.

8. The device of claim 7 further comprising a scribe stop slidably coupled to the scribe guide assembly.

9. The device of claim 7 in which the scribe is adjustable.

10. The device of claim 9 in which the scribe height is adjusted by tilting the adjustable cartridge assembly.

11. The device of claim 9 in which adjustment is performed by a knob adjustment.

12. The device of claim 7 further comprising a hold down magnetically coupled to the sample guide.

13. The device of claim 7 further comprising an adapter for aligning a substantially circular work piece on the rectangular table.

14. The device of claim 13 in which the adapter includes a ferromagnetic ring.

15. The device of claim 7 in which the adjustable scribe is held in place by a scribe carriage lock.

16. The device or claim 7 in which the adjustable scribe extends through an aperture in the rectangular table.

17. The device of claim 7 in which the adjustable scribe includes a diamond tip.

18. The device of claim 7 in which the adjustable scribe includes:

a diamond tipped scribe; and

an adjustable cartridge assembly threadably coupled to the diamond tipped scribe for adjusting a scribe height.

19. The device of claim 7 in which the rectangular table includes a plurality of feet on a bottom side.

20. A method for scribing a bottom side or surface of a sample or substrate while the substrate is oriented with a top side facing up comprising:

placing a sample on a table;

determining a first position for a scribe start by viewing the top side of the substrate;

adjusting a sample guide and thereby pushing the sample to the first position;

determining a second position for a scribe stop by viewing the top side of the substrate;

adjusting a scribe stop guide to the second position by viewing the top side of the substrate;

locking the scribe stop at the second position;

pushing down on the sample; and

pushing the sample guide toward the second position.
