Abstract
A semiconductor wafer saw for dicing semiconductor wafers are disclosed comprising a wafer saw including variable lateral indexing capabilities and multiple blades. The wafer saw, because of its variable indexing capabilities, can dice wafers having a plurality of differently sized semiconductor devices thereon into their respective discrete components. In addition, the wafer saw with its multiple blades, some of which may be independently laterally or vertically movable relative to other blades, can more efficiently dice silicon wafers into individual semiconductor devices.
Claims24
In combination, a semiconductor substrate singulation saw and a chuck for holding a semiconductor substrate comprising:
- a saw having at least two blades supported above a table and oriented to cut mutually parallel paths in the surface of a semiconductor substrate positioned on the table;
- and
- a chuck having at least one cutting pedestal located thereon mounted on the table, the chuck for holding the semiconductor substrate during the cutting thereof by the saw.
A combination of a semiconductor substrate singulation saw and a table for mounting a semiconductor substrate comprising:
- a saw having at least two blades supported above a table and oriented to cut mutually parallel paths in a surface of a semiconductor substrate positioned on the table;
- and
- a chuck having at least one cutting pedestal located thereon mounted on the table, the chuck for holding the semiconductor substrate during cutting thereof by the saw.
A chuck used in semiconductor substrate singulation for holding a substrate to be singulated by a saw having a table comprising:
- a chuck having at least one cutting pedestal located thereon mounted on the table, the chuck for holding the substrate during cutting thereof by the saw.
