摘要： In order to fasten a silicon block (13) on a support (16) for improved further handling, fibre material (22) which is impregnated with adhesive (23) and consists of glass fibres is introduced into an adhesive join (20) between the silicon block and the support. The silicon block (13) is then positioned on the support (16). The fibre material (22) means that the adhesive join (20) is not pressed together too far and is more stable.

摘要： 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) which act from above. The movement means (23) are designed as circulating belts (24), with a suction surface (25) against which the uppermost wafer (12) is made to abut, wherein the abutment of the wafer (12) against the suction surface (25) is enhanced by negative pressure or suction. In order to separate a plurality of wafers (12) located one upon the other, the movement means (23) are subjected to at least one of the following two steps: a) water (30) is jetted with force against the leading edge of the uppermost wafer (12), the water being directed obliquely from beneath the latter b) the movement means (23) guide the wafer (12) over a stripping device (32) which butts against the underside of the moving wafer (12) from beneath and both forces the wafer (12) against the suction surface (25) and generates a braking action thereon. Thereafter, the wafer (12) is moved on to a transporting path (35, 37) in order to be transported on for further processing.
