Claims
- 1. A method for dicing a semiconductor substrate, comprising:
making a first cut at least partially through the semiconductor substrate along a first street; making a second cut at least partially through the semiconductor substrate along a second street, said second cut being laterally spaced a first distance from said first cut; and making a third cut at least partially through the semiconductor substrate along a third street, said third cut spaced a second distance from said second cut, said second distance being a different distance than said first distance.
- 2. The method of claim 1, wherein said making said first, second and third cuts each comprise forming a scribe line on a surface of the semiconductor substrate.
- 3. The method of claim 2, further including cutting substantially through the semiconductor substrate along said scribe lines with subsequent aligned cuts.
- 4. The method of claim 1, wherein said making said first and second cuts are effected at substantially the same time and said making said third cut is effected at a different time relative to said making said first and second cuts.
- 5. The method of claim 1, further comprising repeating a sequence of said making first, second and third cuts across at least a portion of a surface of the semiconductor substrate.
- 6. The method of claim 5, further comprising rotating the semiconductor substrate substantially 90° and forming at least two additional cuts across streets on the surface of the semiconductor substrate.
- 7. The method of claim 1, further comprising making at least one additional cut along another street, said at least one additional cut spaced a third distance from said third cut.
- 8. A method of dicing a semiconductor substrate, comprising:
substantially severing the semiconductor substrate along a first street; substantially severing the semiconductor substrate along a second street that extends substantially the same direction as said first street and is spaced a first substantial distance apart from said first street; and substantially severing the semiconductor substrate along a third street extending in substantially the same direction as said first and second streets, said third street spaced a second distance from said second street, said second distance being different than said first substantial distance.
- 9. The method of claim 8, further comprising forming a scribe line along said first street.
- 10. The method of claim 9, wherein said forming said scribe line precedes said substantially severing the semiconductor substrate along said first street.
- 11. The method of claim 8, further comprising forming a scribe line along said second street.
- 12. The method of claim 11, wherein said forming said scribe line precedes said substantially severing the semiconductor substrate along said second street.
- 13. The method of claim 8, further comprising forming a scribe line along said third street.
- 14. The method of claim 13, wherein said forming said scribe line precedes said substantially severing the semiconductor substrate along said third street.
- 15. The method of claim 8, wherein said substantially severing the semiconductor device along said first and second streets are effected substantially simultaneously.
- 16. The method of claim 15, wherein said substantially severing the semiconductor device along said first and second streets are effected at a different time than said substantially severing the semiconductor device along said third street.
- 17. The method of claim 16, wherein said substantially severing the semiconductor device along said third street is effected independently of substantially severing the semiconductor device at any other location.
- 18. The method of claim 8, further comprising repeating a sequence of said substantially severing the semiconductor device along each of said first, second, and third streets.
- 19. The method of claim 8, further comprising substantially severing the semiconductor device along another street spaced a third distance apart from an adjacent one of said first, second, or third streets.
