Description
Technical Field
[0001] The present application relates to the technical field of testing equipment, and in particular to a semiconductor device performance testing device and a testing process. Background Art
[0002] Semiconductor devices are electronic devices with conductivity between good conductors and insulators. They use the special electrical properties of semiconductor materials to complete specific functions. They can be used to generate, control, receive, transform, amplify signals and perform energy conversion. Usually, semiconductor devices need to undergo various performance tests before leaving the factory to evaluate the performance of the device under different working conditions, including temperature, humidity, mechanical stress, etc., so as to ensure its stability and reliability in long-term use and guarantee product performance and quality.
[0003] For example, in the existing Chinese patent with the publication number CN219609129U, a semiconductor device high temperature performance test device is disclosed, which includes a box body, a placement table is fixed on the bottom inner wall of the box body, two plug-in slots are provided on the top outer wall of the placement table, a detection metal contact piece is installed on the bottom inner wall of the plug-in slot, a signal transmitter is installed on one side of the box body, and an oscilloscope is installed on the outer wall of the box body on the signal transmitter side; a wind hood is fixed on the top inner wall of the box body, and a plurality of air inlet holes are provided on the outer wall of the wind hood. Through the above-mentioned prior art, the semiconductor device contacts the detection metal contact piece, and the cooperation of the heating wire and the temperature controller can heat the semiconductor device and perform high temperature performance testing.
[0004] However, the above prior art has the following technical defects: When the above-mentioned prior art is used, the contact on the semiconductor device is inserted into the plug slot to contact the detection metal contact piece, the second rotating motor is operated to drive the turntable to rotate, and the two sliders are driven to move relative to each other under the cooperation of the limit block and the limit slot, and the semiconductor device is clamped and fixed by the L-shaped clamping plate, and the temperature controller controls the heating wire to heat the semiconductor device. The first rotating motor drives the fan blade to rotate to improve the heating efficiency of the semiconductor device, and the signal fed back by the oscilloscope is observed to judge the high-temperature performance of the semiconductor device. The above-mentioned device mainly blows the heat energy generated by the heating wire to the semiconductor device through the rotation of the fan blade. There is a certain distance between the heating wire and the semiconductor device. The temperature controller can control the temperature of the heating wire, but when the heat energy of the heating wire acts on the semiconductor device through wind blowing, its heat energy will be dispersed and reduced, that is, the temperature during detection cannot be controlled, so that the data obtained by the above-mentioned device is not accurate.

It cannot meet the simultaneous testing of multiple devices under various environmental conditions, such as accelerated aging and performance stability testing under low temperature, high humidity and other environmental conditions, to detect and evaluate the overall performance of the device under different working conditions.

DETAILED DESCRIPTION
[0040] The following is combined with Figure 1-Figure 18 This application is described in further detail.
[0041] The embodiments of the present application disclose a semiconductor device performance testing device and a testing process, which can perform accelerated aging and performance stability tests on multiple semiconductor devices under different environmental conditions at one time, and comprehensively test and evaluate the overall performance and quality of the semiconductor devices to simplify the transportation of semiconductor devices between devices with different testing functions.
[0042] Reference Figure 1 and Figure 2As shown, in the first aspect, the present application provides a semiconductor device performance detection device, including an equipment support 1 and a detection box 11 mounted on the equipment support 1. In the present embodiment, a rectangular cover 13 is preferably provided on one side of the detection box 11 through four side round rods 12 for sliding. It should be noted that the four side round rods 12 are divided into two groups and fixedly installed on one side of the rectangular cover 13; round rod holes 111 for inserting and installing the side round rods 12 are symmetrically opened on the detection box 11, and a detection device 2 is provided in the rectangular cover 13 and the detection box 11; the semiconductor devices to be tested are placed in the detection box 11 in turn, and then the rectangular cover 13 is pushed to close the detection box 11. The operation of the detection device 2 can alternately test multiple semiconductor devices under different environmental conditions at the same time. According to different detection times, long-term accelerated aging detection or short-term performance stability test can be achieved.
[0043] Reference Figures 3 to 5 As shown, specifically, the detection device 2 includes a servo motor 22 installed on the equipment support 1 through a motor seat 21, and the rotating shaft of the servo motor 22 penetrates the detection box 11 and extends into the interior thereof. The detection box 11 is provided with a circular shaft hole 112 for the rotating shaft of the servo motor 22 to penetrate, and the detection box 11 is provided with a cross back plate 23 connected to the end of the rotating shaft of the servo motor 22. It should be noted that the servo motor 22 is set to rotate 90 degrees each time it operates, that is, each operation can drive the cross back plate 23 to rotate 90 degrees. In this embodiment, preferably, an annular seat 25 is slidably provided on the cross back plate 23 through four square rods 24, and square holes 251 adapted to the square rods 24 are symmetrically provided on the annular seat 25.
[0044] Four square rods 24 are divided into two groups and symmetrically fixedly installed on one side of the cross back plate 23. The annular seat 25 can be limitedly slidably set on the square rod 24 through the square hole 251 opened. The technical effect to be achieved is that when the cross back plate 23 is driven by the servo motor 22 to rotate, the annular seat 25 can be driven to rotate together, and when the annular seat 25 is subjected to force, it can also slide on one side of the cross back plate 23. A monitoring component 3 is provided on the annular seat 25, which is used to place multiple semiconductor devices at the same time and monitor their operating status; in this embodiment, preferably, three groups of buckling mechanisms 4 are provided in the detection box 11, and the three groups of buckling mechanisms 4 are respectively located below and on the left and right sides of the annular seat 25.
[0045] When placing semiconductor devices to be tested into the test box 11, the annular seat 25 can be pulled outward for a certain distance first so that multiple semiconductor devices can be docked and placed on the monitoring component 3 in sequence. Then, the annular seat 25 is pushed into the test box 11 to reset, and the rectangular cover 13 is pushed to close the test box 11. The operation of the snap-fit mechanism 4 can snap related test components with different functions onto semiconductor devices at corresponding positions for testing. In conjunction with the operation of the servo motor 22, each semiconductor device can be driven to change position regularly to achieve performance testing of semiconductor devices with different functions.
[0046] Reference Figure 6 As shown, considering the need to connect with the semiconductor device and place it, so that the semiconductor device can be accelerated aging and performance stability test in the startup operation state, the monitoring component 3 includes a monitoring element board 31 installed on the side of the annular seat 25 facing the cross back plate 23. In this embodiment, four placement seats 32 connected to the monitoring element board 31 are preferably arranged on the outer ring surface of the annular seat 25, and the placement seat 32 has a docking portion 321 connected to the semiconductor device, and the annular seat 25 is provided with queue holes 252 on both sides of the placement seat 32. The monitoring element board 31 has integrated circuits and controllers. When the semiconductor device is placed on the placement seat 32 and connected to the docking portion 321, the monitoring element board 31 can control the operation of the semiconductor device and monitor the operation of the semiconductor device in real time. Since this is a prior art, it will not be described in detail here. When placing semiconductor devices for testing, four semiconductor devices can be placed on four placement seats 32 at one time and connected to each docking portion 321 respectively. The placement seat 32 and the annular seat 25 are fixedly connected, so when the annular seat 25 slides due to the driving force, it can drive the placement seat 32 and the monitoring element board 31 to move synchronously, so as to facilitate the placement and removal of semiconductor devices.
[0047] Reference Figure 7 and Figure 8 As shown, in order to better perform performance testing of semiconductor devices at various positions under different environmental conditions, the snap-fit mechanism 4 includes three magnet side seats 42 slidably arranged on the inner wall of the detection box 11 through the side block 41, and the three magnet side seats 42 are respectively located below and on the left and right sides of the cross back plate 23; three side slide grooves 113 for installing the side block 41 are opened on the inner wall of the detection box 11, and the side slide grooves 113 are provided with inner round rods 43 penetrating the side block 41, and the side block 41 has a through hole 411 adapted to the inner round rod 43, and the inner round rod 43 is sleeved with a push spring 44 connected to the side block 41. The push spring 44 always has a driving force to push the side block 41 to slide in a direction away from the cross back plate 23, that is, in the absence of other external forces, there is always a certain distance between the three magnet side seats 42 and the cross back plate 23, which will not hinder the rotation of the cross back plate 23.
[0048] Reference Fig. 9 and Fig.10 As shown, since it is necessary to synchronously drive the magnet side seats 42 at three different positions to move toward the cross back plate 23 without affecting the rotation of the cross back plate 23, the three magnet side seats 42 are respectively connected with a bottom side frame 45, a side frame one 46 and a side frame two 47, the bottom side frame 45 is located below the annular seat 25, and the side frame one 46 and the side frame two 47 are respectively located on the left and right sides of the annular seat 25; the ends of the cross back plate 23 are provided with rectangular slots 231 adapted to the magnet side seats 42, it should be noted that the cross back plate 23 is in the shape of a cross, and thus has four ends, each of which is provided with a rectangular slot 231; the cross back plate 23 is provided with an electromagnet block 48 at the rectangular slot 231. When the electromagnet block 48 is powered on and started, it will generate suction on the magnet side seat 42, and then drive the magnet side seat 42 into the rectangular slot 231. At this time, the bottom side frame 45, side frame one 46 and side frame two 47 installed on the three magnet side seats 42 will be respectively engaged with the placement seat 32 at the corresponding position, and the cover is set on the semiconductor device.
[0049] Continue to refer to Fig.10 As shown, considering the need to test the performance stability of semiconductor devices in a high temperature environment and the quality test when the semiconductor devices are rapidly reduced from a high temperature state to a low temperature state, a temperature test unit 5 is provided on the bottom side frame 45 and the side frame 1 46. The temperature test unit 5 includes a U-shaped plate 51 installed on the bottom side frame 45, a heating tube 52 is provided on the U-shaped plate 51, an L-shaped plate 53 is provided on the side frame 1 46, two small fans 54 are symmetrically installed on the L-shaped plate 53, and an air outlet 114 is symmetrically opened at the bottom of the detection box 11. First, the electromagnet block 48 is energized to drive the three magnet side seats 42 to enter the corresponding rectangular notches 231 respectively, driving the bottom side frame 45, the side frame 1 46 and the side frame 2 47 to buckle at the corresponding placement seat 32; start the heating tube 52 and the small fan 54 to operate, and the semiconductor device located at the bottom side frame 45 can be tested at high temperature, while the semiconductor device located at the side frame 1 46 can be tested by wind. By cooperating with the air outlet 114 , the operation of the small fan 54 can also discharge the high-temperature air in the detection box 11 to prevent the temperature in the detection box 11 from being too high.
[0050] After the test is completed, the electromagnet block 48 is turned off to release the suction force on the magnet side seat 42. At this time, under the action of the push spring 44, each magnet side seat 42 will slide away from the rectangular notch 231 in the direction away from the cross back plate 23, so that the bottom side frame 45, the side frame 1 46 and the side frame 2 47 are reset and no longer engaged with the placement seat 32. The servo motor 22 is started to run clockwise for 90 degrees, so that the semiconductor device after the high temperature test can be transferred to the side frame 1 46, and then the electromagnet block 48 is powered on again to drive the bottom side frame 45, the side frame 1 46 and the side frame 2 47 to engage again and cover the corresponding semiconductor device. At this time, the operation of the small fan 54 can quickly cool down the high-temperature semiconductor device, so as to detect the operation of the semiconductor device when it changes from high temperature to low temperature.
[0051] Reference Fig.11 As shown, on the basis of the first embodiment, in order to be able to perform stability tests on semiconductor devices in different high-humidity environments, the detection device 2 also includes a high-humidity test unit 6 disposed in the rectangular cover 13 and the detection box 11. The high-humidity test unit 6 includes a thermal energy plate 60 and an L-shaped thermal insulation plate 61 installed on the side of the rectangular cover 13 facing the detection box 11. After the rectangular cover 13 is pushed to close the detection box 11, the thermal energy plate 60 and the L-shaped thermal insulation plate 61 will be in the annular seat 25. The surface temperature of the thermal energy plate 60 is relatively high when it is started, and the L-shaped thermal insulation plate 61 can provide thermal insulation protection for the monitoring element board 31. The detection box 11 and the second side frame 47 are provided with a condensation assembly 7, which is used to cooperate with the thermal energy plate 60 to form a high-humidity environment at the second side frame 47, so as to perform performance tests on the semiconductor devices at this position under the high-humidity environment.
[0052] Continue to refer to Fig.11 As shown, the detection box 11 is provided with a water storage tank 62, and two folding hoses 64 connected to the water storage tank 62 are installed on the outer wall of the rectangular cover plate 13 through an external pipe seat 63. Two middle pipes 65 connected to the two folding hoses 64 are respectively provided on the rectangular cover plate 13, and the middle pipes 65 are located above the thermal energy plate 60. A circular pipe hole 131 for installing the two middle pipes 65 is opened on the rectangular cover plate 13. When the rectangular cover plate 13 is pulled and pushed normally, the folding hose 64 can be extended and contracted accordingly. The water in the water storage tank 62 can flow into the two middle pipes 65 through the two folding hoses 64.
[0053] Reference Fig.12As shown, considering that the water in the water tank 62 needs to be dripped slowly onto the thermal energy plate 60 in the form of water drops, the end of the middle pipe 65 away from the folding hose 64 is connected to a control pipe 66, and a water outlet pipe 67 toward the thermal energy plate 60 is installed on the control pipe 66. An adjustment cap 68 is threadedly connected to one end of the control pipe 66, and an inner round bead 69 connected to the adjustment cap 68 is provided in the inner cavity of the control pipe 66. It should be noted that the diameter of the inner round bead 69 is adapted to the inner cavity of the control pipe 66, and the position of the inner round bead 69 in the control pipe 66 can be adjusted by rotating the adjustment cap 68, and the flow rate is adjusted through the pores, so that the water can slowly drip onto the thermal energy plate 60 in the form of drops. Since the surface temperature of the thermal energy plate 60 is relatively high, when water drops onto the thermal energy plate 60, water vapor is generated. The water vapor passes upward through the queue holes 252 and is dispersed around the placement seat 32 above the thermal energy plate 60. Under the action of the water vapor, a high humidity environment is formed here, so that the performance stability of the semiconductor devices here can be tested in a humidity environment.
[0054] Reference Figures 13 to 15 As shown, since the water vapor needs to be reused to condense, another form of high humidity environment is formed at the position of the second side frame 47, and the performance of the semiconductor device is tested in a humidity environment. The condensation component 7 includes a condensation plate 71 installed on the top of the inner cavity of the detection box 11, and a small air cooler 72 is fixed on the side wall of the detection box 11. The side wall of the detection box 11 is provided with an assembly port 115 for installing the small air cooler 72, and an exhaust port 116 for discharging cold air. A U-shaped sponge 73 and an arc-shaped guide plate 74 are installed on the second side frame 47. A vent 741 is opened through the arc-shaped guide plate 74, and the arc-shaped guide plate 74 has a guide groove 742 on the side facing the condensation plate 71. The operation of the small air cooler 72 can keep the surface of the condensation plate 71 at a low temperature at all times. After the water vapor contacts the low-temperature surface of the condensation plate 71 through the vent holes 741 on the arc-shaped guide plate 74, it can be condensed. The condensed water droplets can flow to the U-shaped sponge 73 through the guidance of the guide grooves 742 on the condensation plate 71 and the arc-shaped guide plate 74, making the U-shaped sponge 73 wet. When the side frame 47 is buckled on the placement seat 32 at the corresponding position, the wet U-shaped sponge 73 will cover the semiconductor device arranged there to form another humid environment, thereby realizing performance testing of the semiconductor device in a humid environment.
[0055] When the cross back plate 23 is stationary, the four placed semiconductor devices will be in four different environments: high temperature environment, windy environment, water vapor high humidity environment, and humid environment; so that the semiconductor devices can be tested for performance in a single specific environment, and can also be tested alternately in different environments with the drive of the servo motor 22 to detect the overall performance stability of the semiconductor devices in different environments. In addition, when a long-term cycle alternating test is performed, the purpose of accelerating the aging test of the semiconductor devices can be achieved.
[0056] Reference Fig.16 and Fig.17 As shown, on the basis of the first and second embodiments, in order to facilitate the placement and removal of semiconductor devices, when the inspection is completed, the staff pulls out the rectangular cover 13 to open the inspection box 11, and the annular seat 25 can be taken out synchronously. A fastening member 8 is provided on the rectangular cover 13, and the fastening member 8 includes a square transmission rod 81 that is symmetrically slidably arranged on the rectangular cover 13. The rectangular cover 13 is symmetrically provided with a limiting slide groove 132 for limiting the sliding of the two square transmission rods 81. A rubber fastening rod 82 is provided at one end of the square transmission rod 81 facing the inspection box 11.
