- a wafer handling system has been developed in which a plate made of glass, silicon, hard plastic, or the like, called a support plate, is bonded to a wafer to be ground to supplement the strength of the wafer to prevent cracks and warpage. Since the strength of the wafer is compensated for by the wafer handling system, the conveyance of the thinned wafer can be automated.
- the wafer and the support plate are bonded together using various thermoplastic resins or adhesives. Then, after thinning the wafer to which the support plate is attached, the support plate is separated from the wafer before dicing the wafer. For example, in order to thin the wafer to 150 ⁇ m or less, it is very preferable to firmly bond the wafer and the support plate.

- a laminated body in which a semiconductor wafer (supported substrate) is temporarily fixed to a support plate (support) used in a wafer support system will be described as an example.
- the laminate according to the present invention includes a separation layer made of an inorganic material.
- the separation layer is made of an inorganic material and is altered by absorbing light. As a result, the separation layer loses its strength or adhesiveness before being irradiated with light. Therefore, by applying a slight external force (for example, lifting the support), the separation layer is broken and the support and the supported substrate can be easily separated.
- the said inorganic substance should just be the structure which changes in quality by absorbing light, for example, can use 1 or more types of inorganic substances selected from the group which consists of a metal, a metal compound, and carbon suitably.
- the metal compound refers to a compound containing a metal atom, and can be, for example, a metal oxide or a metal nitride.
- examples of such inorganic substances include, but are not limited to, gold, platinum, palladium, cobalt, rhodium, iridium, calcium, ruthenium, osmium, manganese, molybdenum, tungsten, niobium, tantel, bismuth, antimony.

- an inorganic compound “degenerates” means that the separation layer composed of the polymer can be broken by receiving a slight external force, or the adhesive force between the separation layer and the structure in contact with the separation layer is reduced. It means a phenomenon that causes a situation to occur.
- the separation layer can be formed on the support by known techniques such as sputtering, chemical vapor deposition (CVD), plating, plasma CVD, and spin coating.
- the thickness of the separation layer is not particularly limited as long as it is a film thickness that can sufficiently absorb the light to be used. For example, a film thickness of 0.1 to 10 ⁇ m is more preferable.

- the separation layer is provided between the support and the adhesive layer. That is, an adhesive layer is provided between the separation layer and the supported substrate. With such a configuration, it is possible to prevent the light applied to the separation layer via the support from reaching the supported substrate. For example, when a fine structure to be protected is formed on the surface of the supported substrate in contact with the adhesive layer, such a fine structure can be prevented from being adversely affected by light irradiation.
- the separation layer facing the adhesive layer is flat (unevenness is not formed), the separation layer can be easily formed and can be applied evenly. Is possible.

- the other layers are made of a material that transmits light.
- a layer imparting preferable properties to the laminate can be appropriately added without hindering the incidence of light on the separation layer.
- the wavelength of the light which can modify an inorganic substance changes with kinds of the inorganic substance which comprises the separated layer. Therefore, the material constituting the other layer does not need to transmit all the light, and can be appropriately selected from materials that can transmit light having a wavelength capable of altering the inorganic substance.
- the separation layer is fixed on the support directly or via another layer, and the support layer is supported by the separation layer and the support substrate being bonded via the adhesive layer. Temporarily fixed.
- the other layer may be an adhesive layer that bonds the separation layer and the support.
- the support is light transmissive. This is intended to allow the light to pass through the support and reach the separation layer when irradiated from the outside of the laminate. Therefore, it is not always necessary for the support to transmit all light, and it is sufficient that the support can transmit light to be absorbed by the separation layer (having a desired wavelength).
- the support is configured to support the supported substrate. Therefore, the support body only needs to have a strength necessary for preventing damage or deformation of the supported substrate when the supported substrate is processed and transported.
- the material of the support may be glass or silicon, but can be employed as the support if it can achieve the above-mentioned purpose.
- the adhesive layer is configured to cover and protect the surface of the supported substrate while simultaneously bonding and fixing the supported substrate to the support. Therefore, the adhesive layer needs to have adhesiveness and strength to maintain the support substrate to be fixed to the support and to cover the surface to be protected of the support substrate when the supported substrate is processed or transported. There is. On the other hand, when it becomes unnecessary to fix the supported substrate to the support, it is necessary that it can be easily peeled off or removed from the supported substrate.
- the adhesive layer usually has strong adhesiveness, and is composed of an adhesive whose adhesiveness is lowered by some treatment or has solubility in a specific solvent.
- the adhesive for example, various adhesives known in the art such as acrylic, novolak, naphthoxan, hydrocarbon, and polyimide can be used as the adhesive constituting the adhesive layer according to the present invention. It is.
- the adhesive layer is preferably formed using a resin other than a photocurable resin (for example, a UV curable resin). This is because the photocurable resin may remain as a residue around the minute unevenness of the supported substrate after the adhesive layer is peeled or removed.
- a resin other than a photocurable resin for example, a UV curable resin
- an adhesive that dissolves in a specific solvent is preferable as a material constituting the adhesive layer. This is because the adhesive layer can be removed by dissolving in a solvent without applying physical force to the supported substrate. When the adhesive layer is removed, the adhesive layer can be easily removed without damaging or deforming the supported substrate even from the supported substrate with reduced strength.
- FIG. 1 is a diagram illustrating a method for manufacturing a stacked body and a process for separating a semiconductor wafer from the stacked body.

Abstract
Description
本発明に係る積層体は、光透過性の支持体と、上記支持体によって支持される被支持基板と、上記被支持基板における上記支持体によって支持される側の面に設けられている接着層と、上記支持体と上記被支持基板との間に設けられている、無機物からなる分離層とを備えており、上記分離層は、上記支持体を介して照射される光を吸収することによって変質するようになっており、上記分離層における上記接着層に対向する側の面が平坦になっている。
