METHOD AND DEVICE FOR BONDING OF SUBSTRATES
A method and device for bonding a first substrate with a second substrate inside a sealed bonding chamber. The method includes: a) fixing of the first and second substrates, b) arranging of the first and second substrates, c) mutual approaching of the first and second substrates, d) contacting the first and second substrates at respective bond initiation points, e) generating a bonding wave running from the bond initiation points to side edges of the substrates, and f) influencing the bonding wave during course of the bonding wave, wherein targeted influencing of the bonding wave takes place by a regulated and/or controlled change of pressure inside the bonding chamber.
WAFER DICING USING FEMTOSECOND-BASED LASER AND PLASMA ETCH
Methods of dicing semiconductor wafers, each wafer having a plurality of integrated circuits, are described. A method includes forming a mask above the semiconductor wafer, the mask including a layer covering and protecting the integrated circuits. The mask and a portion of the semiconductor wafer are patterned with a laser scribing process to provide a patterned mask and to form trenches partially into but not through the semiconductor wafer between the integrated circuits. Each of the trenches has a width. The semiconductor wafer is plasma etched through the trenches to form corresponding trench extensions and to singulate the integrated circuits. Each of the corresponding trench extensions has the width.
GRINDING EQUIPMENT
A grinding equipment includes: a frame which has a central shaft disposed collinearly to one side of the polishing wheel and rotates about the central shaft; a plurality of seating portions which are disposed on the upper side of the frame, each have a space formed in the central portion thereof, seat a workpiece on the upper surfaces thereof, and are arranged radially from the central shaft of the frame; a plurality of vacuum portions which are disposed in the central portions of the plurality of seating portions respectively, seat the workpiece on the upper surfaces thereof, and each have a plurality of flow channels so as to secure the workpiece by suctioning air through the flow channels; and a control unit for controlling the rotation of the frame.
Method of separating a back layer on a singulated semiconductor wafer attached to carrier substrate
A method for forming an electronic device includes providing a wafer having a plurality of die formed as part of the wafer and separated from each other by spaces. A layer of material is disposed atop a major surface of the wafer and the layer of material is placed adjacent to first carrier substrate comprising a first adhesive layer. The wafer is singulated through the spaces to form singulation lines. A second carrier substrate comprising a second adhesive layer is placed onto an opposite major surface of the wafer. The method includes moving a mechanical device adjacent to and in a direction generally parallel to one of the first carrier substrate or the second carrier substrate to separate the layer of material in the singulation lines. In one example, the second adhesive layer has an adhesive strength that is less than that of the first adhesive layer.
Solar array system and method of manufacturing
A space-grade solar array includes relatively small cells with integrated wiring embedded into or incorporated directly onto a printed circuit board. The integrated wiring provides an interface for solar cells having back side electrical contacts. The single side contacts enable the use of pick and place (PnP) technology in manufacturing the space-grade solar array. The solar cell is easily and efficiently packaged and electrically interconnected with other solar cells on a solar panel such as by using PnP process. The back side contacts are matched from a size and positioning standpoint to corresponding contacts on the printed circuit board.
Dividing method of workpiece and laser processing apparatus
A dividing method of a workpiece includes a dicing tape sticking step of sticking a dicing tape to the workpiece. A first laser processing step includes irradiating the workpiece with a laser beam with such a wavelength as to be absorbed by the workpiece along a first direction to form first laser-processed grooves. A first expanding step includes expanding the dicing tape in a second direction to enlarge the width of the first laser-processed grooves. A second laser processing step includes irradiating the workpiece with the laser beam with such a wavelength as to be absorbed by the workpiece along the second direction to form second laser-processed grooves, and a second expanding step includes expanding the dicing tape in the first direction to enlarge the width of the second laser-processed grooves.
Substrate bonding apparatus

SUBSTRATE TREATMENT APPARATUS
A substrate treatment apparatus according to an embodiment includes a treatment tank to store a chemical solution to treat a substrate, a pipe having a discharge port through which an air bubble is discharged from a bottom of the treatment tank toward the substrate, and a rod body disposed between the discharge port and the substrate to divide the air bubble.
SUBSTRATE PROCESSING APPARATUS, SUBSTRATE PROCESSING METHOD AND BONDING METHOD
A substrate processing apparatus includes a chuck configured to attract and hold a substrate; an observer configured to observe multiple positions within a second surface of the substrate attracted to and held by the chuck, the second surface being opposite to a first surface thereof which is in contact with the chuck; and an analyzer configured to analyze observation results of the multiple positions. When a singularity regarding a height from a surface of the chuck attracting and holding the substrate exists on the second surface, the analyzer specifies a position of the singularity on the chuck.
