A starting point for separating a separation layer and a layer to be separated is formed in a process member. A first step of irradiating a first portion of the process member with first laser light in a frame-like shape and a second step of irradiating at least part of a region which is irradiated with the first laser light with second laser light are performed. The process member includes a first substrate, the separation layer, the layer to be separated, and an adhesive layer which are stacked in this order. In the first portion, the adhesive layer overlaps with the first substrate with the separation layer and the layer to be separated provided therebetween. In the first step, the first laser light is absorbed by at least the layer to be separated and the adhesive layer. In the second step, the second laser light is absorbed by at least the separation layer.

Method for forming separation starting point and separation method

A film-like member is supported in a flat shape by vacuum suction. A plurality of lift pins are arranged in a planar configuration and bear a film-like member placed on their upper ends. Tubular pads made of rubber for holding the film-like member by vacuum suction are attached to upper portions of the lift pins. The height of the lift pins can be adjusted by a screw fastening mechanism. The deformation of the film-like member can be corrected to a flat or concavely curved shape by suction from the pads. When the correction cannot be achieved by suction alone, the correction may be supplemented by ejection of air from a nozzle.

Film-like member support apparatus

An object is to provide a novel separation method or a novel manufacturing method of a device. In the case where a bond of M-O&#x2014;W (M is a given element) is divided by application of physical force, a liquid is absorbed into the gap, whereby the bond becomes bonds of M-OH HO&#x2014;W with a longer bond distance and the detachment can be promoted accordingly. In the detachment, a roller such as a drum roller can be used. Part of the roller surface may have adhesiveness. For example, an adhesive tape or the like may be put on part of the roller surface. By rotating the roller, the layer to be separated is wound and detached from the substrate having an insulating surface.
