Contiguous wafer boat

Claim 2

A boat for supporting a batch of semi conductor wafers comprising support means having a plurality of slots for supporting a series of wafers in spaced, parallel relation with the slots extending from one end of the support means to the other with no obstruction extending beyond the ends so that a second boat of the same kind may be positioned in end-to-end relation with the first boat and the adjacent wafers between the mating ends of the boat will have the same spacing between them as the rest of the adjacent wafers, and a pair of pickup tubes secured to said support, with the tubes extending generally perpendicular to the wafer-receiving spaces defined by the slots, said tubes being sized to receive the tines of a fork-like tool for lifting the boat.

Claim 3

The boat of claim 1 wherein said support means includes a plurality of elongated rods arranged in spaced, parallel relation, with said rods having said slots formed therein to receive the wafers, and the support means further includes a pair of cross members secured to said rods and holding the rods in spaced, parallel relation, said cross members being located between the ends of said rods so as not to extend beyond the ends of the rods.

Claim 4

A boat for supporting a batch of semi conductor wafers comprising support means having a plurality of slots for supporting a series of wafers in spaced, parallel relation with the slots extending from one end of the support means to the other with no obstruction extending beyond the ends so that a second boat of the same kind may be positioned in end-to-end relation with the first boat and the adjacent wafers between the mating ends of the boat will have the same spacing between them as the rest of the adjacent wafers, and said support means includes a plurality of elongated rods arranged in spaced, parallel relation, with said rods having said slots formed therein to receive the wafers, and the support means further includes a pair of cross members secured to said rods and holding the rods in spaced, parallel relation, said cross members being located between the ends of said rods so as not to extend beyond the ends of the rods, and a pair of elongated pickup tubes extending generally parallel to the plurality of elongated rods which support the wafers and being secured to said cross members on the opposite side from said rods.

Claim 5

A boat for supporting a batch of semi conductor wafers comprising support means having a plurality of slots for supporting a series of wafers in spaced, parallel relation with the slots extending from one end of the support means to the other with no obstruction extending beyond the ends so that a second boat of the same kind may be positioned in end-to-end relation with the first boat and the adjacent wafers between the mating ends of the boat will have the same spacing between them as the rest of the adjacent wafers, and said support means includes a plurality of elongated rods arranged in spaced, parallel relation, with said rods having said slots formed therein to receive the wafers, and the support means further includes a pair of cross members secured to said rods and holding the rods in spaced, parallel relation, said cross members being located between the ends of said rods so as not to extend beyond the ends of the rods, and a pair of elongated pickup tubes extending generally parallel to the plurality of elongated rods which support the wafers and being secured to said cross members on the opposite side from said rods.

Claim 6

Apparatus for supporting batches of semi-conductor wafers or other such disc-shaped items comprising an elongated cart or other carrier, a plurality of boats positioned in end-to-end relation on said carrier, each of said boats having a plurality of slots for supporting a batch of semi-conductor wafers in spaced, parallel relation, the end slot of each boat is closely spaced from the end of that boat so that the adjacent wafers at the end of adjacent boats are spaced the same as the rest of the wafers and a pair of pickup tubes on each of said boats extending generally parallel to the end-to-end direction of the boats.

Claim 7

Apparatus for supporting batches of semi-conductor wafers or other such disc-shaped items comprising an elongated cart or other carrier, a plurality of boats positioned in end-to-end relation on said carrier, each of said boats having a plurality of slots for supporting a batch of semi-conductor wafers in spaced, parallel relation, the end slot of each boat is closely spaced from the end of that boat so that the adjacent wafers at the end of adjacent boats are spaced the same as the rest of the wafers and a pair of pickup tubes on each of said boats extending generally parallel to the end-to-end direction of the boats.

Claim 8

The apparatus of claim 4 wherein each of said boats has a plurality of spaced parallel rods with the rods of one boat being positioned in end-to-end alignment with the rods of an adjacent boat, said slots being formed in said rods.

Claim 9

The apparatus of claim 5 wherein said carrier has a pair of elongated side rails, and said boat rods includes a pair of bottom rods and a pair of side rods, said rods being held in spaced, parallel relation by a pair of cross rods, including side portions angling upwardly and outwardly from a lower central portion, said cross rod side portions engaging the side rails of the carrier.

Claim 10

The apparatus of claim 4 wherein said pair of pickup tubes is positioned below the wafer support slots, with the tubes being spaced from each other to straddle the carrier and thus be accessible for a pickup tool.
