A cutting apparatus for dividing a wafer that is stuck to an adhesive tape in which the adhesive layer is cured by ultraviolet light and that is supported by an annular frame through the adhesive tape, into individual chips, includes: a holding unit having a frame support section that supports the annular frame, and a wafer table that is formed of a transparent body and supports the wafer; a cutting unit including, in a rotatable manner, a cutting blade for cutting the wafer; and an ultraviolet light applying unit that applies ultraviolet light, the ultraviolet light applying unit being disposed facing the cutting blade in such a manner that the wafer table is interposed therebetween. The ultraviolet light applying unit applies ultraviolet light to a region where the wafer is to be cut by the cutting blade, to form a cured region where the adhesive layer is cured.

A bonding apparatus includes: a first holder configured to hold a first substrate; a second holder disposed to face the first holder and configured to hold a second substrate to be bonded to the first substrate; an imaging unit including a first portion including a first objective lens that captures an image of a first mark formed on the first substrate held by the first holder, and a second portion including a second objective lens that captures an image of a second mark formed on the second substrate held by the second holder; and a mover configured to relatively move the imaging unit, first holder, and second holder in a region between the first holder and the second holder. In the imaging unit, an optical axis of the first objective lens and an optical axis of the second objective lens are not on a same straight line.

A method of forming a semiconductor device includes mounting a bottom wafer on a bottom chuck and mounting a top wafer on a top chuck, wherein one of the bottom chuck and the top chuck has a gasket. The top chuck is moved towards the bottom chuck. The gasket forms a sealed region between the bottom chuck and the top chuck around the top wafer and the bottom wafer. An ambient pressure in the sealed region is adjusted. The top wafer is bonded to the bottom wafer.

A wafer processing method includes emitting a laser beam along an annular line that is a predetermined distance inward of the outer circumferential edge of the first wafer to form, in the first wafer, an annular first modified layer and a first crack extending from the first modified layer to make an appearance on the front surface, thereby causing the first wafer to become warped at an outer circumferential region thereof that lies closer to the outer circumferential edge than does the first modified layer and the first crack; bonding the front surface of the first wafer to a second wafer to form a bonded wafer stack; and grinding a rear surface of the first wafer of the bonded wafer stack to thin the first wafer to a finish thickness.

The present invention is an IC chip mounting apparatus including: a conveyor configured to convey an antenna continuous body on a conveying surface, the antenna continuous body having a base material and plural inlay antennas continuously formed on the base material; an IC chip placement unit configured to place an IC chip on a photo-curable adhesive that is located on a reference position of each antenna in the antenna continuous body; and a light irradiator configured to irradiate, with light, the adhesive of each antenna of the antenna continuous body that is conveyed by the conveyor, wherein the light irradiator is configured to irradiate the adhesive of each antenna with the light, while the IC chip on the adhesive is pressed to the antenna.

A method of fabricating an electronic component includes: controlling a laser cutting tool at a first pulse rate to form a first cut portion in a feature of the electronic component, the feature having opposite first and second sides spaced apart from one another along a first direction, and third and fourth sides spaced apart from one another along a second direction, the first cut portion extending from the third side toward the fourth side; controlling the laser cutting tool at a higher second pulse rate and to form a second cut portion extending from the first cut portion toward the fourth side; and controlling the laser cutting tool at a third pulse rate to form a final cut portion extending from the second cut portion toward the fourth side, the third pulse rate less than the second pulse rate.

Provided is a method capable of efficiently polishing the front and back sides of a carrier plate unused after manufacture, which is used in a double-sided polishing process for semiconductor wafers. The method comprises: sandwiching a carrier plate unused after manufacture and to be polished between an upper surface plate and a lower surface plate in the double-sided polishing apparatus, and supplying a polishing liquid while relatively rotating the carrier plate to be polished, the upper surface plate, and the lower surface plate to polish both sides of the carrier plate to be polished, wherein a polishing pad including, on its surface, an abrasive grain-containing layer in which abrasive grains of 2 m or more in grain size are embedded is used as a polishing pad in a double-sided polishing apparatus.

The invention relates to a substrate holder device at least including at least one control valve and at least one substrate holder with a substrate holder surface and a substrate holder rear side. Furthermore, the invention relates to bonding device and a method for bonding.

The present disclosure provides a method for manufacturing a semiconductor package. The method includes disposing a first semiconductor substrate on a temporary carrier and dicing the first semiconductor substrate to form a plurality of dies. Each of the plurality of dies has an active surface and a backside surface opposite to the active surface. The backside surface is in contact with the temporary carrier and the active surface faces downward. The method also includes transferring one of the plurality of dies from the temporary carrier to a temporary holder. The temporary holder only contacts a periphery portion of the active surface of the one of the plurality of dies.
