PEELING APPARATUS AND MANUFACTURING APPARATUS OF SEMICONDUCTOR DEVICE
To eliminate electric discharge when an element formation layer including a semiconductor element is peeled from a substrate used for manufacturing the semiconductor element, a substrate over which an element formation layer and a peeling layer are formed and a film are made to go through a gap between pressurization rollers. The film is attached to the element formation layer between the pressurization rollers, bent along a curved surface of the pressurization roller on a side of the pressurization rollers, and collected. Peeling is generated between the element formation layer and the peeling layer and the element formation layer is transferred to the film. Liquid is sequentially supplied by a nozzle to a gap between the element formation layer and the peeling layer, which is generated by peeling, so that electric charge generated on surfaces of the element formation layer and the peeling layer is diffused by the liquid.
Releasable substrate on a carrier
A method and system provide a releasable substrate on a carrier. The method includes providing the carrier with a bonding layer of radiation curable adhesive; selectively irradiating a first area subsection of the bonding layer with a first radiation for selectively at least partially curing the first area subsection; bringing a substrate in contact with the first area subsection and a second area subsection of the bonding layer; and curing the second area subsection in contact with the substrate for forming an adhesion area between the second area subsection and the substrate. The first area subsection forms a release area with an adhesion force between the bonding layer and the substrate lower in the release area than in the adhesion area as a result of the first area subsection being more cured than the second area subsection prior to being in contact with the substrate.
Apparatuses and methods for forming die stacks
Apparatuses and methods for forming die stacks are disclosed herein. An example method includes dispensing a temporary adhesive onto a substrate, placing a base die onto the temporary adhesive, curing the temporary adhesive, forming a die stack that includes the base die, activating a release layer disposed on the substrate, wherein the release layer is between the substrate and the temporary adhesive, removing the die stack from the substrate, and removing the temporary adhesive from the die stack.
