Definitions
- the present invention relates to a laminating apparatus for laminating a film-like resin on a substrate having irregularities in the production of an electronic circuit board and a semiconductor device. More specifically, the present invention relates to a laminating apparatus in which the film-like resin laminated on the base material has high film thickness uniformity and can suppress the generation of small bubbles (microvoids) between the base material and the film-like resin.
- Patent Document 1 discloses that a thermosetting resin composition or photosensitive material is provided in one of two sealed spaces partitioned by a flexible sheet made of an expansible material.
- the sealed space (the sealed space containing the film-like resin and the base material) in which the flexible sheet made of the expandable material is depressurized by returning only the sealed space to normal pressure or by further applying pressure. )
- Side and an apparatus for laminating the film-like resin and the base material uniformly with the expanded flexible sheet is proposed.
- the flexible sheet swells like a balloon due to the difference in pressure in the sealed space divided into two by the flexible sheet made of the expandable material, so that A contact part deform
- the above-mentioned apparatus is such that the film-like resin and the base material are in contrast to a base material having a pitch that is small or large so that it is difficult to make the film-like resin adhere to the base-surface unevenness completely.
- a device that prioritizes not generating microvoids This device is accompanied by the function of flatly forming the surface of the film-like resin laminated on the base material in the subsequent process with a flat press plate, so the uniformity of the film thickness of the laminated film-like resin is Not so much considered.
- the expanded flexible sheet is pressed against the film-like resin so that the film-like resin is laminated on the substrate by being brought into close contact with the unevenness of the substrate.
- the flexible sheet is difficult to expand in a state of following the unevenness of the laminated body.
- the shaped resin a portion that is strongly pressed by the flexible sheet and a portion that is not so are generated.
- the portion of the film-like resin disposed near the apex of the convex portion of the base material is more strongly pressed by the flexible sheet than the portion that is not so, so that it extends and the film thickness becomes thin. Therefore, there is a tendency that the film-like resin cannot be laminated on the substrate while keeping the film thickness of the film-like resin uniform at a stricter level.
- an object of the present invention is to provide a laminating apparatus that can make the film thickness of the laminated film-like resin uniform at a stricter level.
- the present invention provides a temporary laminate (PL1) formed by adhering one of a film-like resin and a film-like resin with a support film on the irregular surface of a substrate having irregularities on at least one of the front and back surfaces.
- a laminating apparatus for forming the present laminated body in which one of the film-shaped resin and the film-shaped resin with a support film is made to follow the unevenness of the base material, and the temporary laminated body (PL1) is
- the temporary laminate (PL1) can be accommodated in a non-contact state in which the film-shaped resin and the film-shaped resin with a support film are not in contact with each other in the sealed space forming means that can be accommodated and the sealed space formed by the sealed space forming means.
- a laminating apparatus having a laminating mechanism (E1) having pressure laminating means (P1) that pressurizes and laminates on a base material to form a main laminated body from a temporary laminated body (PL1) is provided. The gist.
- the present inventors make the film thickness of the film-like resin laminated on the substrate having irregularities uniform at a stricter level, and even when the irregularities of the substrate are large, the substrate and the film Research has been repeated on the topic of laminating a film-like resin on a substrate without generating microvoids with the resin. In the process, the film thickness of the film-like resin laminated on the substrate having irregularities becomes non-uniform as described above when the film-like resin is laminated on the substrate.
- the expanded flexible sheet cannot be adhered along the unevenness of the base material, and the film-like resin disposed on the base material is strongly pressed against (contacted with) the base material, and It was ascertained that there was a portion that was not so, and the film thickness of the laminated film-like resin was uneven. Therefore, instead of inflating the flexible sheet and pressing it against the film-like resin, the film-like resin cannot be pressed and laminated on the substrate in a so-called non-contact state without using the flexible sheet. I further studied.
- the laminating apparatus of the present invention comprises a sealed space forming means for accommodating a temporary laminate (PL1) formed by stacking and adhering a film-like resin on a substrate, and a film-like resin of the temporary laminate (PL1) in a non-contact state.
- a laminating mechanism (E1) having a pressurizing and laminating means that pressurizes and forms the main laminate along the unevenness of the substrate is provided. Therefore, according to the apparatus of the present invention, it is not necessary to make a laminated body (main laminated body) by making the film-like resin follow the unevenness of the base material by the expanding force of the flexible sheet. In this state, the laminate can be formed by pressurizing the film-like resin.
