摘要:
Methods and systems for dicing a semiconductor wafer including a plurality of integrated circuits (ICs) are described. In one embodiment, a method involves adhering an adhesive tape to a thin water soluble dry film. The method involves applying the thin water soluble dry film adhered to the adhesive tape over a surface of the semiconductor wafer. The method involves removing the adhesive tape from the thin water soluble dry film. The thin water soluble dry film is patterned with a laser scribing process, exposing regions of the semiconductor wafer between the ICs. The method involves etching the semiconductor wafer through gaps in the patterned thin water soluble dry film, and removing the thin water soluble dry film.

Die vorliegende Erfindung betrifft ein Verfahren zum Bonden einer ersten zumindest teilweise metallischen Kontaktfläche eines ersten Substrats (1, 1') mit einer zweiten zumindest teilweise metallischen Kontaktfläche eines zweiten Substrats mit folgenden Schritten, insbesondere folgendem Ablauf: - Aufbringen einer in dem Material mindestens einer der Kontaktflächen zumindest teilweise, insbesondere überwiegend, lösbaren Opferschicht (4) auf mindestens eine der Kontaktflächen, - Bonden der Kontaktflächen unter zumindest teilweisem Lösen der Opferschicht (4) in mindestens einer der Kontaktflächen. Die Kontaktflächen können vollflächig an einem Bondbereich (3) angeordnet sein. Alternativ können die Kontaktflächen aus mehreren Bondbereichen (3') ausgebildet sein, die von Bulkmaterial (5) umgeben oder in Substratkavitäten (2) angeordnet sind. Zur Erzeugung eines Pre-Bonds zwischen den Substraten kann eine Flüssigkeit (z.B. Wasser) verwendet werden.

A system and method are disclosed for applying a die attach epoxy to substrates on a panel of substrates. The system includes a window clamp having one or more windows through which the epoxy may be applied onto the substrate panel. The size and shape of the one or more windows correspond to the size and shape of the area on the substrate to receive the die attach epoxy. Once the die attach epoxy is sprayed onto the substrate through the windows of the window clamp, the die may be affixed to the substrate and the epoxy cured in one or more curing steps. The system may further include a clean-up follower for cleaning epoxy off of the window clamp, and a window cleaning mechanism for cleaning epoxy off of the sidewalls of the windows of the window clamp.

An apparatus and method are described for selectively dispensing a fluid on to a substrate. The apparatus comprises a holder (18) for holding a substrate (20;60;70;90;100), such as a non-planar substrate or circuit board. A fluid dispenser (12) for dispensing fluid, such as an adhesive (62;74), and a positioning device (10) for moving the fluid dispenser are also provided. The positioning device (10) and fluid dispenser (12) are arranged to allow fluid to be dispensed on to a substrate (20;60;70;90;100), held by the holder (18). The holder (18) comprises a tilting mechanism (22,24) that enables a substrate (20;60;70;90;100), held by the holder (18) to be tilted about at least one axis. In use, a substrate (20;60;70;90;100) may be tilted such that the region of the substrate onto which fluid is to be dispensed by the fluid dispenser (12) is at least approximately horizontal thereby preventing unwanted fluid flow under gravity.

The method of the invention comprises placing the conducting powder mass (16) on a holder (14) and the member (12) on the mass (16) and applying a compression force of the member (12) against the mass (16) and the holder (14) before heating the mass (16). The intensity is increased from an initial value up to a predetermined agglomeration value of the conducting powder mass (16) lower than a plastic deformation threshold of the mass (16). The method then comprises maintaining the intensity at the first predetermined value for a predetermined agglomeration duration of the mass (16). Finally, the method comprises increasing the intensity from the first value to a second predetermined value lower than a critical damage threshold of the member (12) but higher than a minimum sintering threshold of the conducting powder mass (16) for a predetermined temperature, the second predetermined value being higher than the first predetermined value.
摘要:
Methods are provided for assembling desired die-cuts from individual die- cut components. Each individual die-cut component may consist of films of various materials, diverse adhesive tapes, diverse foam materials, fabrics, metals and others. Individual die-cut components are assembled onto liners that function as carriers or platforms. The liners may be in individual panels or continuous rolls. Individual die-cut components are assembled onto the liner using computer controlled pick and place equipment with a high degree of accuracy and speed. The liner may consist of a film with controlled adhesive strength to maintain the x-y position of placed individual die-cut components. The die-cut comprising the liner and assembled die-cut components is then used for various purposes, such as holding two parts together, in the assembly of various products, such as cell phones.
