Abstract:
A method for releasing a handler from a wafer, the wafer comprising an integrated circuit (IC), includes attaching the handler to the wafer using an adhesive comprising a thermoset polymer, the handler comprising a material that is transparent in a wavelength range of about 193 nanometers (nm) to about 400 nm; ablating the adhesive through the handler using a laser, wherein a wavelength of the laser is selected based on the transparency of the handler material; and separating the handler from the wafer.
