Description

Technical Field

[0001] This utility model relates to the field of semiconductor manufacturing technology, and in particular to a wafer separation and picking device and system. Background Technology

[0002] Semiconductor manufacturing is a highly precise and complex cutting-edge engineering project, the core of which is building electronic devices at the micrometer to nanometer scale on silicon wafers. The process begins with wafer fabrication, obtaining high-purity silicon wafers through crystal growth, dicing, and grinding. Then, photolithography transfers the circuit pattern to the wafer, followed by etching to create the circuit structure. Doping processes precisely implant impurities to adjust conductivity. Thin film deposition forms insulating and metal layers, ion implantation optimizes device performance, and chemical mechanical polishing achieves surface smoothness. Each step must be carried out in an ultra-clean room, relying on precision equipment to control errors down to the nanometer level. Finally, after testing, dicing, and packaging, chips are manufactured. The entire process involves multiple disciplines such as materials science, physics, and automation, and is the cornerstone of the modern electronics industry.

Traditional wafer transport devices typically employ manual operation or semi-automated equipment, resulting in low efficiency and poor precision.

[0200] The method of using this utility model is as follows:

[0201] (a) Placement Operation

[0202] The wafer-containing carrier is placed on top of the placement element 122, and the wafer-containing carrier is fixed on top of the placement element 122 by an electric chuck.

[0203] The first storage carrier and the second storage carrier are placed at the top of the outer side of the frame element, and below the first lateral drive element 142, on the other side downstream of the conveying drive element 121.

[0204] (II) Opening the lid

[0205] Start the conveying drive element 121 to work, so that it drives the carrier carrying the wafer to move along the axial direction of the conveying drive element 121 toward the opening unit 130 through the placement element 122, until it moves to the designated position (the downstream position of the conveying drive element 121).

[0206] The first rotation drive element 131 is activated, causing it to drive the first adsorption element 134 to rotate horizontally via the second support element 132 and the first longitudinal drive element 133, until the first adsorption element 134 is rotated directly above the carrier containing the wafer.

[0207] The first longitudinal drive element 133 is activated, causing it to drive the first adsorption element 134 to move vertically toward the carrier containing the wafer until the first adsorption element 134 comes into contact with the cover of the carrier containing the wafer. The vacuum pump is then activated to deliver vacuum to the first adsorption element 134, thereby adsorbing the cover of the carrier containing the wafer.

[0208] The first longitudinal drive element 133 operates, causing it to drive the cover of the wafer-carrying carrier to move vertically away from the wafer-carrying carrier via the first adsorption element 134. The first rotation drive element 131 operates, causing it to drive the cover of the wafer-carrying carrier to rotate horizontally via the first adsorption element 134 until the cover of the wafer-carrying carrier is moved away from directly above the wafer-carrying carrier.

[0209] (III) Foam Sorting Operation

[0210] The first lateral drive element 142 is activated, causing it to drive the second adsorption element 146 to move horizontally through the first movable element 143 and the second movable element 145 until the second adsorption element 146 is moved directly below the carrier containing the wafer.

[0211] The second longitudinal drive element 144 is activated, causing it to drive the second adsorption element 146 to move vertically toward the carrier containing the wafer via the second movable element 145, until the second adsorption element 146 comes into contact with the foam packaging material (i.e., foamed plastic) inside the carrier containing the wafer. The vacuum pump is then activated to deliver vacuum to the second adsorption element 146, thereby adsorbing the foam packaging material.

[0212] The second longitudinal drive element 144 operates, causing it to move the foam packaging material vertically away from the carrier containing the wafer via the second adsorption element 146. The first transverse drive element 142 operates, causing it to move the foam packaging material horizontally via the second adsorption element 146 until the foam packaging material is moved directly above the first storage carrier. The second longitudinal drive element 144 operates, causing it to move the foam packaging material vertically towards the first storage carrier until the foam is placed on the first storage carrier.

[0213] (iv) Oil-absorbing paper sorting operation

[0214] The coordinated operation of the first transverse driving element 142, the second longitudinal driving element 144, and the second adsorption element 146 (the specific workflow and sorting operation of method (III) are basically the same, and will not be repeated here) drives the oil-absorbing paper to move vertically toward the direction of the second storage carrier until the oil-absorbing paper is placed in the second storage carrier.

[0215] (V) Wafer Sorting Operation

[0216] The coordinated operation of the first lateral driving element 142, the second longitudinal driving element 144, and the second adsorption element 146 (the specific workflow and sorting operation of method (III) are basically the same, and will not be repeated here) drives the wafer to move vertically away from the carrier containing the wafer until it leaves the carrier.

[0217] (vi) Edge detection operation

[0218] The second lateral drive element 152 is activated, causing it to drive the clamping element 1511 to move horizontally through the cooperation between the first transmission element 156, the second transmission element 158, and the third transmission element 1510.

[0219] The third longitudinal drive element 154 is activated, causing it to drive the clamping element 1511 to move vertically through the cooperation between the first transmission element 156, the second transmission element 158, and the third transmission element 1510.

[0220] The second rotation drive element 155 is activated, causing it to rotate the clamping element 1511 horizontally through the cooperation of the first transmission element 156, the second transmission element 158, and the third transmission element 1510. The third rotation drive element 157 is activated, causing it to rotate the clamping element 1511 horizontally through the cooperation of the second transmission element 158 ​​and the third transmission element 1510. The fourth rotation drive element 159 is activated, causing it to rotate the clamping element 1511 horizontally through the third transmission element 1510, until the clamping element 1511 is moved to a suitable position (so that the clamping element 1511 is located at the wafer adsorbed on the second adsorption element 146, i.e., below the second adsorption element 146).

[0221] Start the clamping element 1511 to clamp the wafer (after clamping the wafer, the second adsorption element 146 loses the negative pressure and thus separates from the wafer);

[0222] Subsequently, the cooperation between the second lateral drive element 152, the third longitudinal drive element 154, the second rotation drive element 155, the third rotation drive element 157, and the fourth rotation drive element 159 drives the wafer to move to the edge finder through the clamping element 1511, and performs edge detection.

[0223] (vii) Storage operations

[0224] The cooperation between the second lateral drive element 152, the third longitudinal drive element 154, the second rotation drive element 155, the third rotation drive element 157, and the fourth rotation drive element 159 drives the wafer to move into the SMIF device via the clamping element 1511 for storage.

[0225] The advantages of this invention are that the carrier lid can be unlocked by the cooperation of the support unit 110, the conveying unit 120, and the opening unit 130, eliminating the tedious steps of manual opening and closing; the sorting unit 140 and the transfer unit 150 can sort foam packaging materials, oil-absorbing paper, and wafers, and the transfer unit 150 can transfer the wafers to the target location. Compared with traditional manual sorting, this improves efficiency, avoids fatigue errors caused by manual operation, and improves sorting accuracy.
