Background

In the semiconductor wafer level packaging process, a wafer is cut into a plurality of dies, good products are picked out from the dies, and the dies are rearranged on a circular substrate for subsequent processing. Since the dice are re-distributed (redistribution), routed, and mounted with balls … … after being reconfigured (reconfiguration), the dice must be placed and positioned on the substrate with high precision. In general, the error is required to be controlled within 2 microns. The prior art method selects a position on the substrate, uses a robot arm to pick up a die, and then places the die at the position selected by the controller.

Detailed Description

The following describes an embodiment of the present invention with reference to fig. 1 to 4. The description is not intended to limit the embodiments of the present invention, but is one example of the present invention.

Referring to fig. 1 and fig. 2, a die-positioning-and-arranging apparatus 100 according to an embodiment of the invention is used for positioning a plurality of dies D on a to-be-arranged region R of a substrate S. The die-positioning-arrangement 100 apparatus includes a holding member 1, an arrangement mechanism 2, a transposing mechanism 3, and a controller 4 electrically connecting the arrangement mechanism 2 and the transposing mechanism 3. The supporting member 1 is an intermediate carrier for supporting a plurality of dies D and has a supporting surface 11 for disposing thereon the plurality of dies D. The supporting member 1 may be, for example, a tray with adhesive property, or a member formed by combining a plurality of vacuum suction nozzles, so that the die D can be fixed thereon.

The arrangement mechanism 2 is used to arrange a plurality of dies D on the supporting surface 11 of the supporting member 1. In one embodiment, the arranging mechanism 2 is a robot arm, and the controller 4 controls the arranging mechanism 2 to arrange the plurality of dies D located in the die storage area Z one by one onto the supporting surface 11 in a suction manner, but the invention is not limited thereto.

The transfer mechanism 3 is provided to transfer the supporting member 1 from the loading position P1 corresponding to the supporting surface 11 to the positioning position P2. The loading direction P1 means that the supporting surface 11 of the supporting member 1 faces the arrangement mechanism 2 and the arrangement mechanism 2 arranges the plurality of dies D. In contrast, the positioning orientation P2 is to position the plurality of dies D in the region R of the substrate S to be arranged by relatively inverting the supporting member 1 and the substrate S such that the supporting surface 11 of the supporting member 1 faces the region R of the substrate S to be arranged and by relative displacement between the supporting member 1 and the substrate S. In fig. 2, the transfer mechanism 3 turns the holding member 1 at an angle to transfer the holding member to the fixed position P2. However, in practice, the substrate S may be turned over, or the supporting member 1 and the substrate S may be turned over at an angle so that the supporting surface 11 of the supporting member 1 faces the region R where the substrate S is to be placed. After the holding member is transferred to the positioning orientation P2, the controller 4 controls the transferring mechanism 3 to separate the holding member 1 and the substrate S, and holds the plurality of dies D in the region to be arranged R. The relative separation may be performed by moving the supporting member 1 away from the substrate S by the transfer mechanism 3 or by moving the substrate S away from the supporting member 1, or may be performed by relative displacement by moving both of them.

The controller 4 is also configured to determine the position of each die D on the supporting surface 11 and determine the region R to be arranged on the substrate S, in addition to controlling the operations of the arranging mechanism 2 and the flipping mechanism 3.

Referring to fig. 3, the die positioning and arranging method provided by the present invention includes a presetting step and a transposing step.

In one embodiment, the supporting member 1 is a square carrier, and the substrate S may be a wafer, glass, PCB, ceramic substrate or other materials, but the invention is not limited thereto. The holding member 1 has a size substantially equal to a unit exposure range of an exposure mechanism that performs exposure processing on the crystal grains D arranged on the substrate S in a subsequent process. That is, the size of the supporting member 1 is determined according to the exposure mechanism used in the subsequent process, and the pitch of the arrangement positions provided for the plurality of dies D on the supporting surface 11 may be further defined by the exposure mechanism. With the design of the supporting member 1 completely corresponding to the exposure mechanism, the relative positions of the plurality of dies D arranged on the substrate S and the relative positions of the dies and the substrate S can be completely matched with the unit exposure range of the exposure mechanism, thereby minimizing the error.

Referring to fig. 4 and 5, another embodiment of the present invention is provided. The difference from the previous embodiment is that the crystal grain positioning and arranging apparatus 100a of the present embodiment further includes a circulating member 5. In the present embodiment, the supporting member 1 is provided in plural, and the arranging mechanism 2 is correspondingly provided in plural, but the number of the supporting member 1 and the arranging mechanism 2 is not necessarily equal. The circulating means 5 is provided to circulate the plurality of holding members 1 to be close to the plurality of arranging means 2 between a position corresponding to the transposing means 3 and a position corresponding to the arranging means 2, the plurality of arranging means 2 arranges the plurality of dies D on the plurality of holding members 1, and the transposing means 3 transposes the plurality of dies D to the plurality of regions to be arranged R.

That is, in the present embodiment, in order to further improve the productivity, a plurality of holding members 1 and a plurality of arranging mechanisms 2 are used. The plurality of arrangement mechanisms 2 operate simultaneously to arrange the plurality of dies D on the plurality of holding members 1. In other words, compared to the previous embodiment, more supporting members 1 can be arranged on a plurality of dies D per unit time in the present embodiment. Thus, the arrangement speed of the single arrangement mechanism 2 can be prevented from being slower than the transposition speed of the transposition mechanism 3, and the transposition mechanism can continuously transpose the supporting member 1.

In the transfer process, the supporting member 1 is also transferred from the feeding position P1 to the positioning position P2, as in the previous embodiment. After the supporting member 1 is transferred to the positioning orientation P2, the controller 4 controls the transferring mechanism 3 to relatively separate the plurality of supporting members 1 and the substrate S, and to retain the plurality of dies D in the region R to be arranged. Thereafter, the transferred holding member 1 is transported to a position corresponding to the placement mechanism 2 by the circulation member 5 to hold the crystal grain again.

By the die-positioning-arrangement apparatus 100a and the die-positioning-arrangement method of the present invention, the turnover mechanism 3 can transpose a plurality of dies D to the region R to be arranged of the substrate S at a time, thereby saving lengthy arrangement time and greatly increasing the speed. In detail, the transfer mechanism 3 can save much time for moving back and forth between the die storage area Z and the substrate S every time the support member 1 is transferred. In a practical example, if the supporting member 1 supports N dies D, the time for the transferring mechanism 3 to transfer the supporting member 1 once is saved by N-1 units compared to the prior art. In addition, the prior art requires one process time for arranging one die, but in the present invention, the plurality of dies D arranged on the supporting member 1 simultaneously contact the substrate S, so the plurality of dies D also require only one process time in total. When the transposing mechanism 3 transposes N dies onto the substrate S at a time, the process time of N-1 unit is saved. In summary, the die-positioning and arrangement apparatus and the die-positioning and arrangement method of the present invention can greatly improve the productivity and further reduce the production cost.
