摘要:
A substrate breaker positively feeds substrate plates to a stick breaker where the sticks are broken from the plate. The sticks are fed upwardly to an elevated chip breaker where chips are broken from the sticks.

Apparatus for the automatic separation, along predetermined bending fracture lines, in basic ceramic platelets of hybrid electronic circuits, which apparatus comprises a support plate, provided with grooves on its lower face extending into close proximity with its upper face, these grooves defining bending lines, disposed in correspondence with the bending fracture lines of a ceramic platelet placed in register above said plate, which grooves define relative bays of the plate which are rigid in bending, these bays corresponding to the single elements into which the platelet is to be subdivided, upper pressing members being present adapted for clamping each element of the platelet against the corresponding bay or square of the plate, which is rigidly supported in correspondence with one single bay or square, lower opposing members being present, acting against each of the remaining bays, these members being retractable on command in a predetermined sequence, the successive bending of the plate along the lines defined by the grooves of said plate being brought about by the action of the upper pressing members, said bending causing the fracture of the ceramic platelet along the predetermined lines coinciding with the grooves of the plate.

A scribing apparatus for manufacturing a solar cell, and a method of manufacturing a solar cell using the same are provided. The scribing apparatus includes a stage part configured to support a substrate having at least one thin film layer, a scribing unit configured to scribe on the at least one thin film layer, and a moving unit configured to move at least one of the stage part and the scribing unit during the scribing process. A method of manufacturing a solar cell using the scribing apparatus includes scribing a first pattern onto a reflective electrode layer using the scribing apparatus, the reflective electrode layer being on the substrate, the scribing apparatus further including a needle installation part having a first needle configured to scribe on one side of the reflective electrode layer, and a second needle configured to scribe on a side surface of the reflective electrode layer.

The invention relates to a device (40) for automatic high-precision cutting of a layer of material joined to a substrate source by means of an embrittled area, said source substrate and layer forming a set which is to be cut and said device comprising cutting means (531, 532) in addition to means (510) for maintaining the position of the set which is to be cut, characterized in that the cutting means comprise a blade which acts upon the set which is to be cut. The invention also relates to a method for using said device.
摘要:
Eine Vorrichtung (10) zum Brechen eines dünnen, plattenförmigen Gegenstands (11), insbesondere eines Substrats oder eines Wafers, entlang einer geritzten Linie (12), mit einer zusammengesetzen Auflage, die eine Grundplatte (14) und eine auf deren Oberseite angeordnete nachgiebige, federnd elastisch verformbare Auflagematte (13) umfasst, sowie mit einem in Richtung auf die Auflagematte verfahrbaren Brechstempel (15), wobei der plattenförmige Gegenstand zum Brechen so auf der der Grundplatte abgewandten Oberseite der Auflagematte aufgelegt ist, dass die Verfahrrichtung des Brechstempels auf die geritzte Line zielt, ist dadurch gekennzeichnet, dass die Auflagematte auf ihrer der Grundplatte zugewandten Unterseite in Verfahrrichtung des Brechstempels und damit im Betrieb unterhalb der geritzten Linie des plattenförmigen Gegenstandes eine nicht bis zur Oberseite der Auflagematte sich erstreckende Freisparung (16) in ihrer der Grundplatte zugewandten Unterseite aufweist. Damit wird mit einfachen Mitteln ein Brechen von dünnen, plattenförmigen Gegenständen verschleißarm und schonend ermöglicht, wobei insbesondere ein Springen des Gegenstands beim Brechen verhindert wird.
摘要:
The invention concerns a method for cutting two material layers (10a, 10b) forming an assembly to be cut (10), which consists in: producing between the two layers a weakened interface (11), defining an interface ring; forming a first region (21) called high-pressure region; forming at least a second region (22a, 22b) called low-pressure region; supplying the high pressure region with a fluid with controlled pressure. The invention is characterized in that the weakened interface can be produced by any type of process known per se and designed therefor, thus not limited to producing a bonding interface; and combined with the high pressure supply the interface ring of the assembly to be cut is etched with at least a blade (30). The invention also concerns a related device.
摘要:
A process for partially sawing the streets or grooves (50) on semiconductor wafers (48). After sawing, the streets (50) can be covered by a protective material (52), and then the wafer continues its processing as before. After the wafer (48) is broken, the protective material (52) may or may not be removed. Additionally, the wafer(50) may be broken into individual chips using a wedge piece (70) that has a number of individual wedges (72) on it, where the individual wedges (70) press against the partially sawn streets (50), causing the wafer (48) to break.
摘要:
A method and a device are provided for obtaining semiconductor bars for laser devices starting from portions of a processed wafer and carrying out the cleavage in ultra-high-vacuum. The cleavage mechanical stresses are impulsive forces and are all applied from the processed side of the wafer through a lowerable shaped member actuated by compressed helical springs, which applies these stresses on the ledging parts of the wafer portion hold on the central region thereof by a fixed support and hold down in position by a suitably shaped centering thrust member. The spring-up occurs by translating the device in the ultra-high-vacuum environment and contrasting a locking lever engaging the lowerable member in its upper position with a fixed cam.
摘要:
Apparatus for automatic scribing and breaking of semiconductor wafers wherein scribing is performed at a scribing station (S) and the scribed wafer transported in the X direction to a breaking station (B) on an X-Y table (3, 9). Scribing and breaking of parallel lines is accomplished by transporting the wafer step-wise in the Y direction by the Y table (3). Rotation of the wafer for scribing and breaking along sets of lines perpendicular to one another is accomplished by a theta table (18) carried on the Y table (3). An impulse bar (28) is carried by the X table (9) for applying force to the bottom surface of the wafer during both scribing and breaking. Scribing and breaking parameters needed to scribe and break the wafer are entered into computer memory and operated upon by computer controls to automate the scribing and/or breaking process.
