Description

Technical Field

[0001] The invention relates to the field of semiconductor chip testing, in particular to a high and low temperature testing device for semiconductor chips. Background Art

[0002] ‌Semiconductor chip high and low temperature testing‌ is an environmental simulation test used to evaluate the performance and reliability of semiconductor chips under extreme temperature conditions. This test simulates high and low temperature environments to detect chemical changes or physical damage that may occur in the chip during thermal expansion and contraction, ensuring that the chip can work normally in harsh environments and meet the functions and performance indicators specified in the design specifications. It can determine whether the chip can operate stably in high or low temperature environments, thereby ensuring the quality and reliability of the product‌.

[0003] When testing semiconductors at high and low temperatures, it is necessary to place the semiconductor in a heating box to increase the temperature of the semiconductor, and then place it in a freezer for rapid cooling, so as to facilitate observation of the thermal expansion and contraction process of the chip. The existing Chinese patent document: CN118409188B discloses a high-temperature test platform for semiconductor chips, wherein a rotating plate is driven into the heating box by an annular slide plate, and a ceramic heating plate inside the heating box heats the semiconductor chip on the placement plate to ensure that the semiconductor maintains the required temperature during the test, so that the semiconductor chip is automatically fed and heated, and a temperature detector measures and monitors the temperature change of the semiconductor, senses and converts the temperature signal in real time to provide accurate temperature data, facilitates test automation and ensures the correctness of the test results, is easy to operate, reduces the operation process, and improves production efficiency. Although the semiconductor chip can be transported, the semiconductor chip is fixed by the placement plate and the clamping plate, and the placement plate will block the bottom of the semiconductor chip, and under the movement of the rotating plate, the heating box can only heat the top of the semiconductor chip, and the heating surface of the semiconductor chip is small, and the heating speed will be slow.

[0030] Example 1: Please refer to Figure 1-Figure 8 The high and low temperature testing equipment of a semiconductor chip shown in the figure comprises an equipment housing 1 and two temperature controllers 2 symmetrically fixedly mounted on the inner wall at the bottom of the equipment housing 1, the two temperature controllers 2 are respectively used for heating and cooling the semiconductor chip, a rotating drum 3 is rotatably mounted on the inner side of the equipment housing 1, three mounting plates 4 symmetrically distributed in the center are arranged on the outer side of the rotating drum 3, two symmetrically distributed clamping plates 5 are arranged on the side of the mounting plate 4 away from the rotating drum 3, the two clamping plates 5 are provided with clamping and positioning for the semiconductor chip, a loading port is provided on the outer side of the equipment housing 1, and the semiconductor chip is conveniently loaded into the equipment housing 1; it also comprises: a feeding mechanism, which is used to rotate and transport the mounting plate 4 to the semiconductor chip, and the feeding mechanism is installed on the inner side of the rotating drum 3; a fixing mechanism, which is used to fix the two clamping plates 5 to the semiconductor chip stably, and the fixing mechanism is installed on the outer side of the mounting plate 4; a discharging mechanism, which is used to safely discharge the semiconductor chip between the two clamping plates 5, and the discharging mechanism is installed on the outer side of the mounting plate 4.

Two arc-shaped racks 11 symmetrically distributed and matched with the conical wheel 10 are installed. The two arc-shaped racks 11 are respectively located above the two temperature controllers 2, so that when the conical wheel 10 contacts the arc-shaped racks 11, the conical wheel 10 can drive the mounting rod 9 to rotate. A sleeve 12 is arranged on the outside of the mounting rod 9. The sleeve 12 is fixedly installed inside the rotating drum 3. One end of the sleeve 12 away from the mounting plate 4 contacts the outside of the conical wheel 10. Three partition frames 28 symmetrically distributed in the center are fixedly installed on the outside of the rotating drum 3, which divide the equipment housing 1 and the rotating drum 3 into three installation spaces. A locking assembly for providing rotational positioning for the mounting rod 9 is also arranged on the outside of the sleeve 12;

[0032] The staff can insert the semiconductor chip between the two clamping plates 5 on the outside of the mounting plate 4 through the discharge port on the equipment housing 1. The driving motor 7 can drive the rotating drum 3 to rotate through the turntable 8, so that the rotating drum 3 drives the partition frame 28 and the mounting rod 9 to move. The mounting rod 9 drives the semiconductor chip to move to the top of the temperature controller 2 through the mounting plate 4. The temperature controller 2 heats the semiconductor chip by shielding it with the partition frame 28. At the same time, the mounting rod 9 can drive the conical wheel 10 to contact the arc-shaped rack 11 on the positioning cylinder 6, so that the mounting rod 9 is in a rotating state during the movement, so that when the temperature controller 2 heats the semiconductor chip, the semiconductor chip can rotate one circle. As the driving motor 7 rotates the rotating drum 3, the heated semiconductor chip can move to the top of another temperature controller 2, so that the temperature controller 2 cools the semiconductor chip, thereby achieving comprehensive heating and cooling of the semiconductor chip, thereby achieving uniform heating and cooling effects.

[0033] The locking assembly includes a positioning ring 31 fixedly mounted on the outer side of the mounting rod 9, the outer side of the positioning ring 31 is in contact with the side of the sleeve 12 away from the conical wheel 10, and a plurality of plug posts 32 symmetrically distributed in the center are slidably mounted on the side of the sleeve 12 away from the conical wheel 10, a sliding cavity for limiting the sliding of the plug posts 32 is provided on the inner side of the sleeve 12, a spring 2 33 is fixedly mounted between the sliding cavity and the plug posts 32, and one end of the plug posts 32 away from the spring 2 33 is an arc-shaped structure, and a plurality of slots for limiting the insertion of the plug posts 32 are provided on the outer side of the positioning ring 31, and the elasticity of the spring 2 33 can be utilized to enable the plug posts 32 to provide locking for the mounting rod 9 through the positioning ring 31;

[0034] When the mounting rod 9 rotates, it can drive the positioning ring 31 to rotate along the outer side of the sleeve 12, so that the plane of the positioning ring 31 pushes the arc-shaped end of the plug post 32 to move, and the plug post 32 can move along the sliding cavity of the sleeve 12 and compress the spring 2 33, and the mounting rod 9 stops rotating, so that the plug post 32 can be inserted into the slot at the current corresponding position on the positioning ring 31, which can prevent the mounting rod 9 from rotating, improve the stability of the mounting rod 9 when performing circular motion, and facilitate the smooth transportation of semiconductor chips.

[0035] Working principle: First, the staff inserts the semiconductor chip between the two clamping plates 5 located on the discharge port of the equipment housing 1, and starts the driving motor 7. The output end of the driving motor 7 drives the turntable 8 to rotate, so that the turntable 8 drives the rotating drum 3 to rotate, and the rotating drum 3 drives the partition frame 28 and the mounting rod 9 to move in a circle with the positioning cylinder 6 as the center. The mounting rod 9 drives the mounting plate 4 to move synchronously, so that the mounting plate 4 drives the semiconductor chip between the two clamping plates 5 to move above the first temperature controller 2. The temperature controller 2 quickly heats the semiconductor chip by using the shielding of the partition frame 28. At this time, the staff inserts the next semiconductor chip to be tested between the two clamping plates 5 located at the discharge port of the equipment housing 1. At this time, the driving motor 7 runs again, so that the mounting rod 9 drives the conical wheel 10 to contact the arc-shaped rack 11 on the positioning cylinder 6. As the mounting rod 9 moves, the arc-shaped rack 11 can drive the mounting rod 9 to rotate through the conical wheel 10, so that the mounting rod 9 drives the semiconductor chip to rotate one circle through the mounting plate 4. At the same time, the mounting rod 9 can drive the positioning ring 31 to rotate synchronously along the outer side of the sleeve 12. The plane of the positioning ring 31 pushes the arc-shaped end of the plug post 32 to move, so that the plug post 32 is received in the sliding cavity of the sleeve 12 and the spring 2 33 is compressed. When the conical wheel 10 is away from the arc-shaped rack 11, the mounting rod 9 stops rotating, and the plug post 32 can be inserted into the slot at the current corresponding position on the positioning ring 31 to provide positioning for the mounting rod 9. The first temperature controller 2 can cool the bottom of the semiconductor chip, and then move the heated semiconductor chip to the top of the second temperature controller 2. The second temperature controller 2 cools the semiconductor chip. The conical wheel 10 contacts the arc-shaped rack 11 located above the second temperature controller 2, so that the second temperature controller 2 can fully cool the semiconductor chip, and the next semiconductor chip can be moved to the top of the first temperature controller 2. Finally, the rotating drum 3 moves the tested semiconductor chip to the discharge port of the equipment housing 1, and the staff can take the tested semiconductor chip, thereby achieving uniform heating and cooling effects, and multiple semiconductor chips can be loaded in sequence for testing in turn, thereby improving the testing efficiency of semiconductor chips.

At the same time, the positioning plate 17 drives the slide bar 16 to move along the slide groove on the mounting plate 4, so that the slide bar 16 drives the slide plate 13 to compress the spring 15, and the elasticity of the spring 15 is used to make the clamp 5 elastic to the outer side of the semiconductor chip, thereby improving the convenience of semiconductor chip installation.

The outer diameter of 7 is smaller than the thickness of the equipment housing 1 to prevent the partition frame 28 from colliding with the sliding roller 27. A top plate 29 is fixedly installed on the side of the U-shaped frame 26 away from the discharge port. The top plate 29 is located directly below the top block 24, so that the top plate 29 can push the top block 24 to move upward.
