## Background
BACKGROUND
Manufacturing a semiconductor device includes forming chips. Chips which support a functionality of the semiconductor device are encased in a common molding material. The chips are bonded to a carrier using a release film. The molding material surrounds the chips. The combined molding material and chips are then separated from the carrier by processing the release film.
Examples of processing the release film include thermal release and ultraviolet (UV) release. In thermal release processes, the release film is heated to a temperature sufficient to reduce an adhesive strength of the release film and the molding material and chips are peeled off the film.
In UV release processes, the release film is exposed to UV radiation in order to reduce the adhesive strength of the release film. In order for UV radiation to reach the release film, the carrier on which the release film is placed is transparent to UV radiation.

FIG. 4 is a flow chart of a method 400 of using a vacuum carrier module in accordance with some embodiments and FIGS. 5A-5 D are schematic cross-sectional views of a vacuum carrier module at various stages during a method of use in accordance with some embodiments.
Referring to FIG. 4, in operation 410 an upward pressure is exerted on a gel film by an aligning material through the hole(s). In some embodiments, such upward pressure is exerted by passing the alignment material through the hole(s) to help ensure that the gel film remains planar. In some embodiments, such pressure is exerted using a pressure exerting tool. In some embodiments, the pressure exerting tool comprises a pump, a compressor or other suitable pressurizing tools. In some embodiments, an amount of pressure exerted is controlled using a control system. In some embodiments, the control system is configured to selectively activate the pressure exerting tool. In some embodiments, the control system is configured to monitor the pressure exerted using pressure sensors located outside of the vacuum carrier module. In some embodiments, the control system is configured to adjust the amount of pressure exerted in response to a weight applied to a top surface of the gel film. The aligning material comprises materials which are not reactive with the gel film. The alignment material does not reach a phase transition temperature at a temperature at which a molding material is placed on top of the gel film. In some embodiments, the alignment material comprises compressed dry air (CDA), N2, other inert gases, silicone oil, or other suitable fluids. An upward pressure exerted by the aligning material from a bottom portion through the top portion of the hole(s) help(s) the gel film in being planar with respect to the substrate. The upward pressure exerted by the aligning material is lower than an adhesive strength between the gel film and the substrate so that the gel film remains fixed on top of the substrate.
In operation 415 at least one chip is placed on top of the gel film. In some embodiments, the upward pressure of the aligning material is increased to compensate for an increased downward force resulting from a weight of the chips on the gel film. In some embodiments, the upward pressure of the aligning material remains constant. Further, in some embodiments, the upward pressure of the aligning material is continuous throughout until the molding material is cured.
FIG. 5A is a cross-sectional view of the vacuum carrier module following operation 415. FIG. 5A includes a vacuum carrier module similar to vacuum carrier module 100 (FIG. 1A). Similar elements have a same reference number increased by 400. Two chips 504 are located on gel film 550. In some embodiments, one chip 504 is placed on gel film 550. In some embodiments, more than two chips 504 are placed on gel film 550. An alignment material 516 is applied to a reservoir 590 through holes 530 in substrate 510.
Returning to FIG. 4, in operation 420 a molding material 506 is disposed over the gel film 550 and cured. In some embodiments, a two-step molding process is used wherein a separate underfill material is first injected beneath the gel film and the substrate followed by over-molding with a second molding material to encapsulate and fill spaces between the gel film and the substrate. The underfill material is any suitable liquid epoxy, deformable gel, silicone rubber, or other suitable material used for underfilling compounds. In some embodiments, the process used is any suitable method known in the art, such as spinning, chemical vapor deposition (CVD) and plasma enhanced chemical vapor deposition (PECVD). In some embodiments, the molding material is cured using heat or ultraviolet (UV) radiation for a period of time sufficient to harden the molding material. In some embodiments, the upward pressure of the aligning material remains constant during operation 420. Further, in some embodiments, the upward pressure of the aligning material is continuous from the previous process until the molding material is cured, while in additional embodiments, the upward pressure of the aligning material is stopped for a period of time after the at least one chip is placed on top of the gel film and before the molding material is placed on top of the gel film.
FIG. 5B is a cross-sectional view of the vacuum carrier module following operation 420. In comparison with FIG. 5A, FIG. 5B includes a molding material 506 disposed over the chips 504 and on top of the gel film 550.
Returning to FIG. 4, in operation 425 a negative pressure or a vacuum is created through the hole(s) of the substrate to detach the gel film from the molding material. Such negative pressure or a vacuum has a sufficient magnitude to detach the gel film from the cured molding material. In some embodiments, the negative pressure or a vacuum which is created through the hole(s) is continuous from after the molding material is cured up until the molding material is detached in operation 430. In some embodiments, the negative pressure or the vacuum is generated using a pump, or another suitable pressure inducing tool. In some embodiments, a control system is used in generating adequate negative pressure. In some embodiments, the control system is used to regulate a magnitude of the negative pressure or the vacuum.
FIG. 5C is a cross-sectional view of the vacuum carrier module following operation 425. In comparison with FIG. 5B, FIG. 5C includes a vacuum 518 exerted on the gel film 550 through the holes 530 at the bottom portion of the substrate 510. Vacuum 518 results in reduced surface area between the gel film 550 and molding material 506. The pressure also results in the gel film 550 not being planar. Supports 540 help to prevent gel film 550 from being pulled into holes 530 by vacuum 518 to reduce a risk of damage to the gel film.
Referring to FIG. 4, method 400 continues with operation 430 in which the molding material is detached from the gel film. In some embodiments, the molding material is peeled off. In some embodiments, the molding material is removed. After the detachment of the molding material from the gel film, gel film 550 retains a shape such that the gel film is planar in accordance with the carrier substrate due to the inherent elasticity of the gel film. The gel film is then reused by placing additional chip(s) and method 400 is repeated.
FIG. 5D is a cross-sectional view of the vacuum carrier module following operation 430. In comparison with FIG. 5C, FIG. 5D includes the gel film 550 returned to the original shape and the molding material 506 being separated from the gel film. In some embodiments, the molding material 506 is removed.
Various embodiments of the present disclosure involve methods to prevent chips 504 and/or the molding material 506 from collecting residue after a molding process. As previously discussed, a gel film 550 is used on substrate 510 during the molding process. The gel film has an elastic property that allows such gel film to be reusable. While molding material 506 is in contact with the gel film 550, a non-adhesive nature of such contact combined with the vacuum release, as in FIG. 5C, helps to prevent residue from the gel film from being left behind on the molding material and/or any other part of the chip(s).
One aspect of this description relates to a vacuum carrier module. The vacuum carrier module includes a substrate having at least one hole and an edge region. There is at least one support on a top surface of the substrate. Further, a gel film is adhered to the edge region of the substrate. The at least one hole fluidly connects a reservoir located above the top surface of the substrate.
