Description

TECHNICAL FIELD

[0001] The utility model relates to chip wet method analysis technical field of layer removal, especially test device. BACKGROUND

[0002] The layer removal technology is widely used in chip production, failure analysis and reverse design fields. The layer removal technology is divided into dry layer removal method and wet layer removal method. The wet layer removal method is a method for removing unnecessary film layers through specific chemical solution and leaving the required film layers.

[0003] In the prior art, when the chip sample is treated by the wet layer removal method, the chip sample is usually placed in a beaker containing a reaction reagent, and after a certain time, the chip sample is taken out from the beaker.

In this way, it cannot be ensured that the reaction time of the multiple chip samples is the same, thereby reducing the reliability of the test results. If the reaction time of the multiple chip samples is to be kept the same, the multiple reaction reagents need to be tested one by one, thereby reducing the test efficiency.

[0031] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0034] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0035] This embodiment provides a test apparatus that achieves the effect of simultaneously reacting multiple samples in multiple reagents, with the reaction time of the multiple samples being the same.

[0036] Specifically, such as Figure 1 and Figure 2 As shown, the experimental apparatus includes a first container 1, a second container 2, and a connecting assembly (not shown in the figure). The first container 1 is provided with a reaction tank 11, and a first partition 12 is provided in the reaction tank 11. The first partition 12 divides the reaction tank 11 into at least two non-communicating sub-reaction tanks 111. The sub-reaction tanks 111 are used to contain reagents. There are at least two second containers 2, which are connected by the connecting assembly. Each second container 2 is detachably inserted into a corresponding sub-reaction tank 111. The second container 2 is provided with a receiving groove 21, which is used to contain a sample (usually a chip or wafer). The receiving groove 21 has at least a hollow structure at its bottom wall.

[0037] Based on the above design, the first container 1 is provided with a reaction tank 11, the reaction tank 11 is provided with a first partition piece 12 to divide the reaction tank 11 into at least two sub-reaction tanks 111 that are not connected to each other, at least two second containers 2 are connected to form a whole through a connecting assembly, each second container 2 is respectively and detachably inserted into a corresponding sub-reaction tank 111, and the second container 2 is provided with a containing groove 21, at least the bottom wall of the containing groove 21 is a hollow structure. In actual use, reagents are respectively injected into the at least two sub-reaction tanks 111, samples are loaded into the containing groove 21 of each second container 2, the connecting assembly is held, each second container 2 is respectively placed into a corresponding sub-reaction tank 111, the reagents in the sub-reaction tank 111 enter the containing groove 21 through the hollow structure and react with the samples, after a certain period of time, the connecting assembly is held to take out the at least two second containers 2 from the first container 1, and the reagents in the containing groove 21 leak back into the sub-reaction tank 111 through the hollow structure, so that multiple samples are simultaneously separated from corresponding reagents, the effect that multiple samples are simultaneously reacted in multiple reagents and the reaction time of multiple samples is the same is achieved, the reliability of test results is improved, and the test efficiency is improved.

[0038] On the other hand, after the samples react with the reagents, the samples need to be cleaned. In the embodiment, after the at least two second containers 2 are taken out of the first container 1, since at least the bottom wall of the containing groove 21 is a hollow structure, the samples do not need to be taken out of the containing groove 21, and the samples in the containing groove 21 can be directly cleaned by spraying cleaning liquid through a washing bottle. The cleaning liquid on the surface of the sample drops and is discharged from the containing groove 21 through the hollow structure. In the prior art, after the samples react with the reagents, the reagents in the beaker need to be poured out or the samples in the beaker need to be clamped out by a clamp, and then the samples are washed by a washing bottle. The reagent pouring method is easy to cause the samples in the beaker to be poured out together with the reagents, which causes the problem of sample loss. The sample clamping method is easy to damage the samples. It can be seen that, in the embodiment, the design that at least the bottom wall of the containing groove 21 is a hollow structure eliminates the operation of pouring the reagents out of the containing groove 21 after the samples react with the reagents, and eliminates the operation of clamping the samples out by a clamp, which solves the problems of sample loss and sample damage.

[0039] In the embodiment, the bottom wall and the side wall of the containing groove 21 are hollow structures. When the second container 2 is placed into the reaction tank 11, the reagents in the reaction tank 11 can quickly enter the containing groove 21. When the second container 2 is taken out of the reaction tank 11, the reagents in the containing groove 21 can quickly leak back into the reaction tank 11, which provides further guarantee that the contact time of the samples in each containing groove 21 with the reagents is the same. When the samples are washed, the design that the bottom wall and the side wall of the containing groove 21 are hollow structures achieves the effect of quickly discharging the cleaning liquid, and thus the cleaning efficiency is improved.

[0040] Optionally, the accommodation groove 21 is provided with a second partition 22, the second partition 22 divides the accommodation groove 21 into at least two sub-accommodation grooves 211, each of which can accommodate a sample, thereby enabling at least two samples to be placed in a second container 2, further improving the test efficiency.

[0041] Further, the second partition 22 is of a hollow structure, so that each sub-accommodation groove 211 is in communication with each other through the hollow structure of the second partition 22. When the second container 2 is placed in the reaction tank 11, the reagent can quickly enter each sub-accommodation groove 211. When the second container 2 is taken out of the reaction tank 11, the reagent in each sub-accommodation groove 211 can quickly leak back into the reaction tank 11, thereby ensuring that each sub-accommodation groove 211 is in contact with the reagent for the same length of time. When the sample is washed, the hollow structure of the second partition 22 achieves the effect of quickly discharging the cleaning liquid, further improving the washing efficiency.

[0042] Optionally, as shown in Figure 3 The connecting assembly includes a cover plate structure 31, which is detachably and sealingly arranged at the opening of the reaction tank 11, so that the cover plate structure 31 cooperates with the first container 1 to form a sealed space, thereby avoiding the overflow of gas generated by the reaction of the reagent and the sample. In addition, if the reagent in the sub-reaction tank 111 is a volatile reagent, the design of the cover plate structure 31 can reduce the volatilization of the reagent, thereby avoiding the problem of reducing the concentration of the reagent.

[0043] Optionally, as shown in Figures 2 to 4 The connecting assembly further includes at least two first connecting members 32, one end of each first connecting member 32 is connected with a corresponding second container 2, and the other end of each first connecting member 32 is connected with the cover plate structure 31, so as to connect the at least two second containers 2 to form a whole.

[0044] In another embodiment, the other end of each first connecting member 32 is connected with each other, so that the at least two second containers 2 are connected by the at least two first connecting members 32 to form a whole.

[0045] Further, the other end of each first connecting member 32 is detachably connected with the cover plate structure 31. When a second container 2 is damaged, the first connecting member 32 connected with the second container 2 is detached from the cover plate structure 31, and then a new set of second containers 2 and first connecting members 32 are assembled on the cover plate structure 31.

[0046] Optionally, as shown in Figure 3As shown, the cover structure 31 comprises a first cover plate 311 and a second cover plate 312, the first cover plate 311 is detachably connected with the second cover plate 312, and the second cover plate 312 is detachably sealed and covered on the opening of the reaction tank 11 through the first cover plate 311. When the second cover plate 312 is damaged or corroded by the gas generated by the reaction of the reagent and the sample, only the second cover plate 312 needs to be replaced, and the replacement of the entire cover structure 31 is avoided, thereby reducing the maintenance cost. In this embodiment, the other end of the first connecting piece 32 is detachably connected with the cover structure 31, and when the second cover plate 312 is replaced, the first connecting piece 32 with the second container 2 also does not need to be replaced, and the first connecting piece 32 connected with the second container 2 can be detached from the cover structure 31.

[0047] It should be noted that the way that the second cover plate 312 is detachably sealed and covered on the opening of the reaction tank 11 through the first cover plate 311 can be various forms. For example, the first cover plate 311 is heavy, and under the gravity of the first cover plate 311, the first cover plate 311 seals and tightly presses the second cover plate 312 on the opening of the reaction tank 11. Alternatively, the sidewall of the first cover plate 311 is provided with a first buckle, one end of the first buckle is hinged with the sidewall of the first cover plate 311, the other end of the first buckle is provided with a protrusion, the sidewall of the first container 1 is provided with a second buckle, the second cover plate 312 is tightly pressed on the opening of the reaction tank 11, the first buckle is rotated, the protrusion abuts against the bottom of the second buckle, the second buckle applies a downward force to the protrusion, the protrusion transmits the force to the first cover plate 311 through the first buckle, so that the first cover plate 311 seals and tightly presses the second cover plate 312 on the opening of the reaction tank 11. When the first cover plate 311 and the second cover plate 312 need to be removed, the first buckle is reversely rotated, so that the protrusion is released from the bottom of the second buckle.

[0048] Optionally, as Figure 3As shown, the cover plate structure 31 further comprises a plurality of second connecting pieces 313, at least two of which are respectively located at opposite sides of the second cover plate 312, and each of the second connecting pieces 313 comprises a first connecting portion 3131 and a second connecting portion 3132, wherein one end of the first connecting portion 3131 is rotationally connected to a side of the second cover plate 312 facing the first cover plate 311, and the axis of rotation of the first connecting portion 3131 is perpendicular to the surface of the second cover plate 312, and the other end of the first connecting portion 3131 is connected to the second connecting portion 3132. When assembling the first cover plate 311 and the second cover plate 312, the first connecting portion 3131 is screwed so that the second connecting portion 3132 is staggered with the first cover plate 311, the first cover plate 311 is placed on the side of the second cover plate 312 away from the first container 1, and then the first connecting portion 3131 is screwed so that the second connecting portion 3132 is located on the side of the first cover plate 311 away from the second cover plate 312, thereby completing the assembly of the first cover plate 311 and the second cover plate 312. When disassembling the first cover plate 311 and the second cover plate 312, the first connecting portion 3131 is unscrewed in the opposite direction so that the second connecting portion 3132 is staggered with the first cover plate 311, and then the first cover plate 311 is removed.

[0049] It can be understood that in other embodiments, the first cover plate 311 and the second cover plate 312 can also be detachably connected by other structures, for example, a magnet is provided on one of the first cover plate 311 and the second cover plate 312, and an iron block is provided in the area opposite to the magnet on the other one, and the detachable connection of the first cover plate 311 and the second cover plate 312 is realized by the magnetic attraction of the magnet and the iron block.

[0050] Optionally, the side of the first partition piece 12 away from the bottom of the reaction tank 11 is flush with the edge of the reaction tank 11, so that when the second cover plate 312 sealing cover is arranged at the opening of the reaction tank 11, the second cover plate 312 sealing cover is pressed on the side of the first partition piece 12 away from the bottom of the reaction tank 11, thereby preventing the reaction gases in each sub-reaction tank 111 from flowing into each other and interfering with the reaction of the samples and reagents in each sub-reaction tank 111.

[0051] It should be noted that if the reaction gases in each sub-reaction tank 111 do not interfere with the reaction of the samples and reagents in each sub-reaction tank 111, the side of the first partition piece 12 away from the bottom of the reaction tank 11 can be located inside the reaction tank 11, i.e. the distance between the side of the first partition piece 12 away from the bottom of the reaction tank 11 and the bottom of the reaction tank 11 is less than the depth of the reaction tank 11, and when the second cover plate 312 sealing cover is arranged at the opening of the reaction tank 11, the second cover plate 312 sealing cover is spaced apart from the side of the first partition piece 12 away from the bottom of the reaction tank 11, and the reaction gases in each sub-reaction tank 111 can flow into each other.

[0052] Optionally, as shown in Figures 2 to 4 The connecting assembly further comprises at least two third connecting pieces 33, each of which is hingedly connected to the other end of a corresponding first connecting piece 32. The second cover plate 312 is provided with connecting holes 3121, the number of which is equal to that of the third connecting pieces 33 and each of which corresponds to one of the third connecting pieces 33. Each of the third connecting pieces 33 is detachably arranged in a corresponding connecting hole 3121. When the first connecting pieces 32 are assembled with the second cover plate 312, the third connecting pieces 33 are arranged through the connecting holes 3121, so that the third connecting pieces 33 and the first connecting pieces 32 are located on opposite sides of the second cover plate 312. Then, the third connecting pieces 33 are rotated so that the two ends of each of the third connecting pieces 33 are arranged on the side of the second cover plate 312 away from the first connecting pieces 32, thereby completing the assembly of the first connecting pieces 32 with the second cover plate 312. When the first connecting pieces 32 are to be disassembled from the second cover plate 312, the first connecting pieces 32 and the third connecting pieces 33 are first lifted upward so that the third connecting pieces 33 are spaced apart from the second cover plate 312. Then, the third connecting pieces 33 are rotated and arranged in the connecting holes 3121 in the reverse direction, thereby completing the disassembly of the first connecting pieces 32 from the second cover plate 312.

[0053] In other embodiments, the other end of the first connecting piece 32 can also be detachably connected to the second cover plate 312 through other structures, for example, the other end of the first connecting piece 32 is provided with a magnet, and the second cover plate 312 is provided with an iron block. The magnet and the iron block are magnetically connected to each other to achieve the detachable connection of the other end of the first connecting piece 32 with the second cover plate 312. Alternatively, the side of the second cover plate 312 facing the first connecting piece 32 is provided with a slot, and the other end of the first connecting piece 32 is detachably arranged in the slot, thereby achieving the detachable connection of the other end of the first connecting piece 32 with the second cover plate 312.

[0054] Further, to improve the reliability of the connection between the first connecting piece 32 and the second cover plate 312, the other end of the first connecting piece 32 and the third connecting piece 33 are hingedly connected through a bolt and a nut (not shown in the figure). Specifically, the bolt is arranged through the third connecting piece 33 and the other end of the first connecting piece 32, and the bolt and the nut are threadedly connected. When the two ends of the third connecting piece 33 are arranged on the side of the second cover plate 312 away from the first connecting piece 32, the bolt and the nut are in a tightened state to lock the included angle between the third connecting piece 33 and the first connecting piece 32. When the first connecting piece 32 is to be removed from the second cover plate 312, the nut is loosened and the third connecting piece 33 is rotated.

[0055] In this embodiment, since the two ends of the third connecting piece 33 are arranged on the side of the second cover plate 312 away from the first connecting piece 32, i.e. the two ends of the third connecting piece 33 are arranged on the side of the second cover plate 312 facing the first cover plate 311, after the first cover plate 311 and the second cover plate 312 are assembled, the first cover plate 311 and the second cover plate 312 are not in the state of being attached to each other, and the third connecting piece 33 is arranged between the first cover plate 311 and the second cover plate 312.

[0056] Optionally, as shown in Figure 5 , the test device further comprises an exhaust pipe 4, the exhaust pipe 4 is arranged through the first cover plate 311 and the second cover plate 312 Figure 5 (not shown), and the reaction tank 11 is communicated with the outside environment through the exhaust pipe 4, so as to achieve the effect of discharging the reaction gas generated by the reaction of the test sample and the reagent from the reaction tank 11, on the one hand, to avoid the problem of excessive gas pressure in the reaction tank 11, and on the other hand, to facilitate the collection and treatment of the reaction gas, and to avoid the problem of polluting the environment and harming the health of the test personnel.

[0057] Optionally, the number of the exhaust pipe 4 is at least two, so as to achieve the effect of rapid exhaust. Further, above each sub-reaction tank 111 corresponds at least one exhaust pipe 4, if the reaction gas in each sub-reaction tank 111 does not flow to each other (the second cover plate 312 can be sealed and capped on the side of the first partition piece 12 away from the tank bottom of the reaction tank 11), then the structure design can make the reaction gas in each sub-reaction tank 111 be able to be discharged; if the reaction gas in each sub-reaction tank 111 can flow to each other (the second cover plate 312 cannot be sealed and capped on the side of the first partition piece 12 away from the tank bottom of the reaction tank 11), then the structure design can make the reaction gas in the reaction tank 11 be able to be discharged more quickly and uniformly.

[0058] Optionally, the side of the exhaust pipe 4 away from the reaction tank 11 is an open structure, so that the reaction gas can be quickly discharged from the reaction tank 11.

[0059] Optionally, the end face of the side of the exhaust pipe 4 facing the reaction tank 11 is flush with the surface of the side of the second cover plate 312 facing the reaction tank 11, so as to avoid the exhaust pipe 4 extending into the reagent in the sub-reaction tank 111, and to ensure the reliability of the exhaust function of the exhaust pipe 4.

[0060] Optionally, as shown in Figure 5 , the test device further comprises a timer 6, which can record the reaction time of the test sample and the reagent. Further, the timer 6 is arranged on the side of the second cover plate 312 away from the first cover plate 311, which improves the integration of the test device, and the timer 6 can be more conveniently viewed.

[0061] Optionally, as shown in Figure 5As shown, the test device further comprises temperature detection elements 5, the number of the temperature detection elements 5 is equal to the number of the sub-reaction tanks 111 and one-to-one correspondence, the temperature sensing probe of each temperature detection element 5 respectively extends into the corresponding one of the sub-reaction tanks 111, and further enables each temperature detection element 5 to respectively detect the temperature in the corresponding sub-reaction tank 111, so as to facilitate real-time monitoring of the temperature of the reagent during the reaction process, so that the test process is more accurate, especially for the sample process which needs to heat the reagent. The structure design achieves the effect of real-time monitoring of the temperature of the reagent. It should be noted that the temperature detection element 5 can be a temperature meter, a thermocouple, a thermal resistance or a thermistor, etc. which can detect the temperature.

[0062] Further, the temperature detection elements 5 are arranged on the first cover plate 311, and the temperature sensing probes of the temperature detection elements 5 pass through the through holes 3122 on the second cover plate 312 and extend into the sub-reaction tanks 111.

[0063] Further, the test device further comprises display elements 7, each temperature detection element 5 is in communication connection with the display element 7, and the display element 7 is used for displaying the temperature value, so as to facilitate observation of the temperature data. In the embodiment, the number of the display elements 7 is equal to the number of the sub-reaction tanks 111 and one-to-one correspondence, each display element 7 is located directly above the corresponding one of the sub-reaction tanks 111, and each display element 7 is in communication connection with the corresponding one of the temperature detection elements 5, which further facilitates observation of the temperature data and prevents the temperature data of the sub-reaction tanks 111 from being confused with each other. Of course, in other embodiments, only one display element 7 can be arranged, and two or more temperature detection elements 5 are in communication connection with the display element 7, and the temperature values detected by the temperature detection elements 5 are displayed on the display element 7. It should be noted that the method of communication connection between the temperature detection element 5 and the display element 7 is a relatively well-known prior art, which will not be described here.

[0064] Optionally, the display elements 7 are arranged on the side of the second cover plate 312 away from the first cover plate 311, which improves the integration of the test device and enables the display elements 7 to be viewed more conveniently.

[0065] Optionally, the side of the first cover plate 311 away from the second cover plate 312 is provided with a handle 3111, which facilitates extraction of the first cover plate 311 and the second cover plate 312.

[0066] In the embodiment, the first container 1 is made of glass, which can be used as a heating container to heat reagents and can be marked with scale lines on the outer wall of each sub-reaction tank 111 to facilitate control of the reagent filling amount. The shape of the first container 1 can be cylindrical, prismatic or other irregular shapes. The second container 2 can be made of corrosion-resistant materials such as polytetrafluoroethylene, or can be made of glass or stainless steel, etc., which can be determined according to actual application requirements. The shape of the second container 2 can be spherical, cylindrical, hemispherical or other irregular shapes.

[0067] As shown in Figure 1 , in the embodiment, the first container 1 is generally a square structure, the first partition 12 is fixed by two plates perpendicular to each other, and then the first partition 12 divides the reaction tank 11 into four sub-reaction tanks 111, that is, the first container 1 has four sub-reaction tanks 111, and the number of the second container 2 is four, and then the test device provided in the embodiment can inject four kinds of reagents into the corresponding sub-reaction tank 111 at a time.

[0068] As shown in Figure 2 , the second container 2 is generally a square structure, the second partition 22 is fixed by two hollow plates perpendicular to each other, and then the second partition 22 divides the containing groove 21 into four sub-containing grooves 211, that is, the second container 2 has four sub-containing grooves 211, and each sub-containing groove 211 contains a test sample, and then the test device provided in the embodiment can put sixteen test samples into the corresponding sub-containing groove 211 at a time. The test of sixteen test samples at a time and the same reaction time of the sixteen test samples with the reagents greatly improves the test efficiency and greatly improves the reliability of the test results.
