The present invention provides a wafer support sheet for use with a stretch frame package for limiting, separating and supporting the wafer, so that the wafer is in a non-contact and micro-moving state during storage and transportation, thereby The wafer acts as a protection. The support table can adopt the concave structure generated by the plastic forming process, as the inside of the support table is hollowed out, so that the support piece has enough space to facilitate the placement of the wafer. The effective area of the wafer does not contact the support sheet, thereby effectively protecting the wafer from contamination, scratching, cracking, or functional failure due to mutual movement. The present invention will be described in detail below in conjunction with the drawings and specific embodiments of the specification.

As shown in the first figure, a wafer support sheet provided by the present invention is placed in the stretch frame package 5, and includes a support body 1. The outer periphery of the support body 1 is provided with a card 41, and the center is provided with a convex portion for The support table 2 of the wafer 7 is placed.

The card position 41 is placed on the outer circumference of the support body 1 to serve as a limit and convenient pick-and-place function, and is formed to cooperate with the notch inside the stretch frame package 5 to reduce the space for the support piece to move inside the container, thereby preventing the wafer 7 from being removed. Scratches, ruptures, and also easy to remove or put into the wafer 7 without contact, effectively avoiding contamination of the wafer 7, facilitating the user and improving efficiency.

As shown in the second and third figures, the present invention is used in conjunction with the stretch box 5 for the limitation, separation and support of the wafer 7, so that the wafer 7 is non-contact and micro during storage and transportation. The state of movement, thereby protecting the wafer 7. The support table 2 can adopt the concave structure generated by the plastic forming process, as the inside of the support table 2 is hollowed out, so that the creation has sufficient space to facilitate the placement of the wafer 7. The effective area of the wafer 7 does not contact the support table 2, thereby effectively protecting the wafer 7 from contamination, scratching, cracking, or functional failure due to mutual movement.

The existing stretch frame 5 is designed to include a single stretch frame 6. When the wafer 7 is placed on a film supported by the stretch frame 6, and the creation is placed under the film, the support film will make the film Maintaining the tension state, the wafer 7 is naturally attached to the bare support table 2, maintaining a relatively firm relative movement relative to the stretch frame 6, helping to maintain the safety of the wafer 7 within the stretch frame 5. If the tension is not in the state of tension, the wafer 7 may be vibrated or "drumed". Such movement may cause unnecessary contact between the wafer 7 and nearby objects, and may even cause bending and cracking of the wafer 7. .

The advantage of this creation is that when a plurality of stretched frames 6 are stacked together, they are separated by the present creation, that is, the creation is placed between the stretched frames 6. Since the middle of the creation has a low structure on both sides and a certain thickness, the wafer 7 is in contact with the stretch frame 6 except for the contact with the support table 2, thereby effectively protecting the wafer 7.

The outer periphery of the support body 1 is provided with lugs 4 which are arcuate and are disposed on both sides of the lugs 4. The card position 41 is disposed on both sides of the lug 4, and the arc-shaped card position 41 is more rounded, which can greatly improve the fixing of the card position 41, and is convenient for taking and lowering.

The support table 2 includes a tapered portion 3 and a platform portion which is disposed at the center of the tapered portion 3. This structure can increase the thickness of the support table 2 and ensure that the wafer 7 can be placed on the platform portion to be flattened.

The inside of the stretch frame 6 is provided with a film, and the center of the film is provided with a through hole, and the support table 2 is placed on the film, and the convex surface tensions the film. This structural form defines the positional relationship and the connection relationship between the present creation and the existing stretch frame 6, so that the stretch frame 6, the film, the present creation and the wafer 7 have an integral cushioning structure, and the cushioning performance is stronger, which further improves the structure. The degree of stability.

The lugs 4 are a plurality of evenly arranged, and the outer circumference of each lug 4 is a circular arc and a circle The arc is on a concentric circle. The arrangement of the lugs 4 ensures balance and stability of the center of gravity, and the outer circumference is a circular arc line, which fits into the notch of the inner wall of the package 5, and is easier to process.

The method of use (working process) of this creation is as follows: A wafer 7 is placed on a film supported by the stretch frame 6, and placed in the frame 5, and then the creation is placed under the film. The film is held under tension, and then the wafer 7 is naturally attached to the support table 2, and then the stretch frame 6 is stacked. Because they are loaded or removed from the container, the tension is maintained, so that the relative movement of the wafer 7 is not affected, thereby protecting the wafer 7 from bending and cracking.

The creation and the frame packing box 5 are used together for the limitation, separation and support of the wafer 7, so that the wafer 7 is in a non-contact and micro-moving state during storage and transportation, thereby playing on the wafer 7. The role of protection. The support table 2 can adopt a concave structure generated by a plastic forming process, as the inside of the support table 2 is hollowed out, so that the support piece has sufficient space for the placement of the wafer 7. The active area of the wafer 7 does not contact the support sheet, thereby effectively protecting the wafer 7 from contamination, scratching, cracking, or functional failure due to mutual movement.
