Abstract:
An apparatus (5) for dicing an integrated circuit substrate having a loader (30) for loading the substrate to the apparatus, said substrate loaded in a first direction corresponding to a loading axis, an inlet rail (35) said inlet rail including a first block (75) movable along said inlet rail (35) to which is loaded the substrate from said loader, wherein said inlet rail is arranged to deliver the first block (75) and substrate towards a chuck table (60) in a second direction orthogonal to the loading axis.
Abstract:
An apparatus for separating a front wafer from a stack of wafers with internal gaps between the wafers is disclosed. The apparatus includes a chuck for gripping the front wafer, coupled to a mechanical arm and a drive for moving the arm to bring the chuck to the front wafer and to separate the wafer from the stack of wafers. Further included is a heater for heating the front wafer so as to raise the temperature within the internal gap between the front wafer and the adjacent wafer of the stack of wafers above the temperature of more distant internal gaps within the stack.
Abstract:
The present invention relates to a multi-wire cutting device (1) with a revolving workpiece mount (2) and a method for cutting solid substrates, for example, for use as wafers in the semiconductor, photovoltaics, optical, ceramics, electro- and magnetotechnical industry.
Abstract:
A system for cutting a plurality of substrates of integrated circuit units comprising a plurality of tables (40, 55), each table including a plurality of trays (37A, 37B, 57A, 57B), each tray arranged to receive one of said substrates; each of said tables selectively movable between a respective loading station (20) for receiving said substrates and a cutting station for cutting the substrates, and a substrate placement device (35) for placing the substrates on the respective trays of said tables; wherein the substrate placement device is arranged to sequentially place substrates on said tables with said tables arranged to sequentially move to the cutting station after receiving the substrates and then return to their respective loading stations for placement of additional substrates.
Abstract:
The invention comprises a device and method for surface cleaning of individual wafers or substrates arranged in a stack along a stacking direction, where a jet of fluid is sent towards the stack in a direction perpendicular to the stacking direction and it is provided a relative movement between the wafer stack and the nozzle in the stacking direction.
