Abstract: A method for making molded glass and ceramic articles including dispersing fine base articles in water, adding coarse base particles to form a bimodal dispersion of base particles, adding aqueous fluorine, agitating the dispersion of base particles and fluorine, and molding the dispersion of base particles and fluorine.

Abstract: A vertical boat comprises a plurality of rods extending vertically in parallel from a base. Each rod has a plurality of slots cut along the length of the respective rod. The slots of each rod are vertically aligned with the slots of the other rods and have top and bottom surfaces that are peaked. The rods are arranged so that a wafer can be jointly received by a corresponding slot from each rod, thereby allowing the boat to hold the wafers in a stack with both sides of the wafers exposed.

Abstract: A carrier for mass transferable semiconductor substrate processing and handling comprises a two part shell including top and bottom semicylindrical halves made from clear fused quartz tubing and releasably assembled to form a cylindrical shell. A semiconductor substrate carrier is removably suspendable in the shell when assembled, and includes four clear fused quartz rods having axially running slots for supporting substrates and clear fused quartz end braces connected to the ends of the rods and clear fused quartz pick-up tubes connected to the end braces.
