Abstract: In the case of a device and a method for cleaning substrates on a carrier, to the underside of which the substrates are fastened so as to be parallel to and slightly apart from one another, the carrier has in its interior a plurality of longitudinal channels, which run parallel to one another. As a result of the sawing of the wafers, they merge, via openings, into interstices between the substrates. As a result of a relative movement, an elongate tube, from which cleaning fluid is let out, is introduced into one of the longitudinal channels, the relative movement being achieved substantially through moving of the carrier.

Abstract: A silicon block is firmly connected to a carrier for being moved together for further working by sawing, cleaning or the like. The carrier consists of plastic, for example of glass-fibre-reinforced plastic, and has in its interior a number of continuous longitudinal channels. These longitudinal channels are sawn into, and so cleaning fluid can then be introduced into the intermediate space between the sawn-up wafers in order to flush out sawing remains.

Abstract: In order to fasten a silicon block on a support for improved further handling, fiber material is introduced into an adhesive joint between the silicon block and the support. The fiber material is impregnated with adhesive and consists of glass fibers. The silicon block is then positioned on the support. The fiber material assures that the adhesive joint is not pressed together too far and is more stable.

Abstract: In a method of separating wafers (12) from a vertical wafer stack (16), the wafers (12) are transported away individually from above via movement means (23). The movement means (23) include circulating belts (24), with a suction surface (25) against which the uppermost wafer (12) abuts, the abutment of the wafer against the suction surface (25) being enhanced by negative pressure. To separate a plurality of wafers (12) located one upon another, the movement means (23) are subjected to at least one of the following two steps: a) water (30) is forcefully jetted against the leading edge of the uppermost wafer (12), the water being directed obliquely from beneath the latter, or b) the movement means (23) guide the wafer (12) over a stripping device (32) which butts against the underside of the moving wafer and both forces the wafer against the suction surface (25) and generates a braking action thereon. Thereafter, the wafer (12) is moved to a transporting path (35, 37) to be transported for further processing.

The essential point is that a pallet (1) which can be filled on two sides is used and that the previous turning back of the pallet after the part has been removed can be omitted.
