Description

Technical Field

[0001] This utility model relates to the field of wafer fixture technology, specifically a metallographic microscope stage support fixture. Background Technology

[0002] A wafer is a silicon ingot that has been cut, rolled, sliced, chamfered, polished, laser-etched, and packaged to become the basic raw material for integrated circuit factories. In order to ensure the quality of the wafer, it is usually placed on a microscope stage by a wafer holder after the wafer is manufactured.

[0003] Publication No. CN 217507293 U discloses a microscope stage holder fixture for easy wafer placement and removal. By setting a fixing plate and using a push handle to slide the fixing plate along a groove, it clamps the wafer placed within a retaining edge, thereby improving the wafer's stability and the stability during inspection and observation, thus greatly enhancing the device's practical value. By setting the front end of the fixing plate in an arc shape and symmetrically arranged with the retaining edge, it can clamp and fix wafers of different diameters within a certain diameter range, greatly improving the device's flexibility and practical value. It has advantages such as wafer placement and fixing function, significantly improving stability during moving inspection and observation, and flexible adjustment of the fixed wafer size, greatly enhancing its practical performance and value. It effectively solves the problems and shortcomings of existing devices. However, this patent still has the following problems in actual use:

[0004] Although this microscope stage holder for easy wafer loading and unloading can clamp and fix wafers of different diameters within a certain range by setting the front end of the fixing plate in an arc shape and symmetrically aligning it with the side guard, the curvature of the outer side of the wafer varies with different diameters, while the curvature of the fixing plate is fixed. Therefore, the contact area between the fixing plate and the wafer surface differs when clamping and fixing wafers of different sizes, resulting in varying clamping and fixing effects. Consequently, stable clamping of wafers of different diameters cannot be achieved, and wafer wobbling or movement is likely to occur, affecting wafer observation.

[0005] Therefore, a metallurgical microscope stage support fixture is proposed to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this invention is to provide a metallographic microscope stage support fixture to solve the problem mentioned in the background art. Because the curvature of the outer side of wafers of different diameters is different, while the curvature of the fixing plate is fixed, the contact area between the fixing plate and the wafer surface varies when clamping and fixing wafers of different sizes. Therefore, the clamping and fixing effect is also different. Consequently, when clamping wafers of different diameters, stable clamping of the wafer cannot be achieved, and wafer shaking or movement easily occurs, affecting wafer observation.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a metallurgical microscope stage support fixture, comprising a wafer fixing mechanism and a clamping bracket mounted on the top of the wafer fixing mechanism;

[0008] The wafer fixing mechanism is provided with an adjustment mechanism at its bottom and an adjustment plate at its top.

[0009] Also includes:

[0010] The wafer fixing mechanism includes a fixing support, and a spiral limiting bracket is fixedly installed inside the fixing support. The clamping bracket is rotatably connected to the fixing support.

[0011] The clamping bracket has several rotating levers fixedly installed on its outer side, and clamping grooves are formed around its inner perimeter.

[0012] The clamping slide groove has a clamping sliding rod fixedly installed inside, and a clamping sliding sleeve is slidably connected to the outside of the clamping sliding rod.

[0014] Preferably, a clamping spring is fixedly installed on one side of the limiting slider, and a spring telescopic rod is provided inside the clamping spring. A first arc-shaped plate is fixedly installed on the side of the clamping spring and the spring telescopic rod away from the limiting slider, and rotating supports are fixedly installed on both sides of the first arc-shaped plate.

[0015] Preferably, a second arc-shaped plate is rotatably connected to the outer side of the rotating support, and a clamping rotating rod is rotatably connected to the inner side of each of the two second arc-shaped plates. The clamping rotating rod is rotatably connected to the limiting slider.

[0016] Preferably, the adjustment mechanism includes an adjustment base, a rotating bracket symmetrically mounted on one side of the top of the adjustment base, a rotating knob rotatably connected to the outer side of the rotating bracket, a rotating worm gear fixedly mounted on one side of the rotating knob, and the rotating worm gear rotatably connected to the rotating bracket.

[0017] Preferably, a rotating worm gear is engaged with one side of the rotating worm, the rotating worm gear is rotatably connected to the adjusting base, the adjusting disc is fixedly installed on the top of the rotating worm gear, and an adjusting groove is provided inside the adjusting disc.

[0018] Preferably, an adjusting sliding rod is fixedly installed inside the adjusting groove, and an adjusting sliding sleeve is slidably connected to the outside of the adjusting sliding rod. The adjusting sliding sleeve is fixedly installed at the bottom of the fixed support, and the fixed support is slidably connected to the adjusting plate.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: This metallurgical microscope stage support fixture can achieve multi-point clamping of wafers through the first arc-shaped plate and the second arc-shaped plate, enabling clamping and fixing of different sizes, while improving the stability of wafer clamping. Utilizing the sliding connection between the adjusting sliding sleeve and the adjusting sliding rod, the movement of the fixed support and the wafer can be realized, facilitating wafer observation. The specific details are as follows:

[0020] 1. By setting up a wafer fixing mechanism, wafers of different sizes can be placed on the clamping bracket. By rotating the lever, the clamping bracket can be rotated. Utilizing the sliding connection between the spiral limiting bracket and the clamping limiting card, the clamping limiting card causes the clamping sliding sleeve to slide outside the clamping sliding rod. At the same time, the clamping sliding sleeve causes the limiting slider to move. When the second arc plate contacts the surface of the wafer, the second arc plate can be rotated under the action of the rotating support. At the same time, the elastic force of the clamping spring can be used to move the first arc plate. Through the first and second arc plates, multi-point clamping of the wafer can be achieved, enabling clamping and fixing of different sizes, while improving the stability of wafer clamping.

[0021] 2. By setting up an adjustment mechanism, not only can the rotating knob drive the rotating worm gear to rotate, but the meshing connection between the rotating worm gear and the rotating worm wheel can also be used to rotate the adjustment disk and the wafer. At the same time, the sliding connection between the adjustment sliding sleeve and the adjustment sliding rod can be used to move the fixed support and the wafer, which facilitates the observation of the wafer.
