AI Technical Summary

Technical Problem

In the prior art, during the vacuum coating process of cleaved semiconductor laser bars, it is impossible to ensure that the cleavage surfaces of each bar are at the same level, resulting in uneven coating. In particular, if the heat furnace source is not designed properly, the beam path of the recessed bar will be blocked by the highly raised bar, affecting the coating effect on the light-emitting surface.

Method used

A vacuum sample holder was designed, including a sample holder and a swinging assembly. The swinging assembly drives the sample holder to swing around the swing axis. Combined with the rotating transmission assembly and the heating assembly, it ensures that the cleavage surface of each bar is evenly coated. The vacuum sample holder drive system and vacuum processing system are used to achieve precise processing and uniform coating of samples.

Benefits of technology

Through the swing and rotation transmission of the sample holder, the cleavage surface of each bar is uniformly coated, avoiding coating unevenness, improving coating uniformity and process control accuracy, and effectively avoiding beam obstruction, especially when the heat furnace source is improperly designed.

Description

Vacuum sample holders, vacuum sample holder drive systems, and vacuum handling systems Technical Field

[0001] The present disclosure relates to the technical field of vacuum equipment, and in particular to a vacuum sample holder, a vacuum sample holder driving system, and a vacuum processing system. Background Art

[0002] Vacuum sample holders are commonly used in vacuum processing, such as in vacuum coating. Vacuum coating is widely used in various production and daily life fields, such as the production of high-power laser diodes. The operating principle of high-power laser diodes is to form a laser resonant cavity between the two cleavage planes of a semiconductor crystal, thereby emitting laser light. Obtaining high-quality cleavage planes is a necessary and key technology. Oxides on the cleavage planes can cause catastrophic optical mirror damage (COMD), resulting in a significant reduction in the performance of optical devices.

[0003] Currently, the mainstream processing method for semiconductor laser bars is to apply a passivation film to the fresh cleavage surfaces of the bars after vacuum cleavage using ultra-high vacuum physical vapor deposition. This protects the cleavage surfaces from oxidation due to contact with air. In the existing technology, a substrate sheet approximately 20-32 mm in length, 12-15 mm in width, and 100-150 μm in thickness is transferred to an ultra-high vacuum environment. A cleavage tool is then used to cleave the bars longitudinally into bars approximately 1-5 mm in length (the cavity length). Multiple cleaved bars, such as dozens, are stacked on the cleavage tool and then transferred to a hollow coating tray, where they are held in place by a spring. At this point, the cleavage surfaces of the bars are located on the upper and lower sides of the tray, facilitating subsequent passivation coating.

[0004] A drawback of existing technology is that when cleaved bars are placed on a tray, it's impossible to ensure that the cleavage surfaces of each bar are at the same level; dozens of bars may have varying heights. Consequently, during coating in the passivation chamber, the beam path is blocked by highly protruding bars, preventing it from reaching recessed bars and causing uneven coating on the luminous surface. This problem is most pronounced during thermal furnace coating, as the thermal furnace is typically designed with a flange mounting port below the chamber, but at an angle to the chamber's axis. If the furnace is positioned to the side of a highly protruding bar, beam obstruction to the recessed bars is exacerbated.

Fig. 2 is a schematic diagram showing the structure of a swing assembly 120 of the vacuum sample holder 100 according to some embodiments of the present disclosure.

[0034] As shown in Figure 1, in some embodiments of the present disclosure, the vacuum sample rack 100 may include a sample rack 110 and a swing assembly 120. The sample rack 110 is used to carry samples. The swing assembly 120 is connected to the sample rack 110 and is used to drive the sample rack 110 to swing. As shown in Figure 2, the swing assembly 120 may include a swing frame 121 and a swing transmission assembly 122. The swing frame 121 is connected to the sample rack 110. The swing transmission assembly 122 is used to drive the swing frame 121 to swing around the swing axis. Through the rotation of the swing frame 121, the samples carried on the sample rack 110 can reach different inclination angles, which facilitates more precise processing of the samples.

[0035] As shown in FIG2 , in some embodiments of the present disclosure, a swing frame 121 may include a swing arm 12101 and a base 12102. The swing arm 12101 is connected to a swing transmission assembly 122. The base 12102 is fixedly connected to the swing arm 12101. The swing arm 12101 receives a drive from the swing transmission assembly 122 to swing about a swing axis and drive the base 12102 to swing.

[0036] As shown in FIG2 , in some embodiments of the present disclosure, the swing transmission assembly 122 may include a swing transmission shaft 12201 and a distal swing transmission gear 12202. The swing transmission shaft 12201 is used to receive a rotational drive (for example, for receiving a rotational drive from a swing drive device 300 as shown in FIG7 ). The distal swing transmission gear 12202 is fixedly connected to the distal end of the swing transmission shaft 12201. The swing frame 121 may include a swing arm gear 12103.

[0039] As shown in Figure 2, in some embodiments, the swing frame 121 may further include a swing arm bearing seat 12104. The swing arm gear 12103 is a ring gear that is sleeved outside the swing arm bearing seat 12104 and fixedly connected to the swing arm bearing seat 12104 to drive the swing arm bearing seat 12104 to rotate. The distal end of the swing arm bearing seat 12104 is fixedly connected to the swing arm 12101, thereby driving the swing arm 12101 to swing. The swing arm bearing seat 12104 can be cylindrical. In some embodiments, the proximal end of the swing arm bearing seat 12104 can be rotatably connected to the mounting frame 130 through, for example, a bearing and an intermediate piece (for example, a sleeve fixedly connected to the mounting frame 130), thereby realizing a rotational connection between the mounting frame 130 and the swing arm 12101, so that the mounting frame 130 is used to support the swing frame 121. In some embodiments, the proximal outer portion of the swing arm bearing seat 12104 can be directly connected to the mounting frame 130 through, for example, a bearing, to achieve a rotational connection between the mounting frame 130 and the swing arm 12101, so that the mounting frame 130 is used to support the swing frame 121.

[0040] FIG3 shows a schematic structural diagram of the rotation transmission assembly 140 of the vacuum sample holder 100 according to some embodiments of the present disclosure.

[0041] As shown in Fig. 3, in some embodiments of the present disclosure, the vacuum sample holder 100 may further include a rotation transmission assembly 140. The rotation transmission assembly 140 is connected to the sample carrier 110 to drive the sample carrier 110 to rotate around a rotation axis.

[0042] As shown in Figure 3, in some embodiments of the present disclosure, the rotation transmission assembly 140 may include a rotation transmission shaft 141, a distal rotation transmission gear 142 and a gear transmission mechanism 143. The rotation transmission shaft 141 is used to receive a rotation drive (for example, for receiving a rotation drive of the rotation drive shaft device 400 as shown in Figure 7). The distal rotation transmission gear 142 is fixedly connected to the distal end of the rotation transmission shaft 141. The gear transmission mechanism 143 is connected to the distal rotation transmission gear 142 to receive a driving force. As shown in Figures 1, 2 and 3, the sample carrier 110 may include a sample carrier gear 111, and the sample carrier gear 111 is connected to the gear transmission mechanism 143, which is used to receive the power of the distal rotation transmission gear 142 through the gear transmission mechanism 143 to drive the sample carrier 110 to rotate.

[0043] As shown in FIG3 , in some embodiments of the present disclosure, the gear transmission mechanism 143 may include a first transmission gear 14301, a first transmission shaft 14302, a second transmission gear 14303, a third transmission gear 14304, a second transmission shaft 14305, and a fourth transmission gear 14306. The first transmission gear 14301 meshes with the distal rotation transmission gear 142. The proximal end of the first transmission shaft 14302 is fixedly connected to the first transmission gear 14301. The second transmission gear 14303 is fixedly connected to the distal end of the first transmission shaft 14302. The third transmission gear 14304 is connected to the second transmission gear 14303, for example, by meshing or via a transmission mechanism. The proximal end of the second transmission shaft 14305 is fixedly connected to the third transmission gear 14304. The fourth transmission gear 14306 is fixedly connected to the distal end of the second transmission shaft 14305 and meshes with the sample carrier gear 111 to drive the sample carrier 110 to rotate about the rotation axis.

[0044] As shown in FIG3 , in some embodiments of the present disclosure, the gear transmission mechanism 143 may further include at least one intermediate transmission gear 14307. The at least one intermediate transmission gear 14307 is disposed between the second transmission gear 14303 and the third transmission gear 14304 to connect the second transmission gear 14303 and the third transmission gear 14304. Those skilled in the art will appreciate that, although FIG3 shows only one intermediate transmission gear 14307, this is merely exemplary, and the gear transmission mechanism 143 may also include two or more intermediate transmission gears 14307. The gear transmission mechanism 143 shown in FIG3 is merely exemplary. The gear transmission mechanism 143 may also include other numbers of transmission gears and / or transmission shafts, and may achieve different combinations of transmission gears and / or transmission shafts to receive power from the distal rotation transmission gear 142 and drive the sample carrier 110 to rotate.

[0045] FIG4 shows a schematic diagram of the internal structure of the swing arm 12101 according to some embodiments of the present disclosure.

[0046] As shown in Figure 4, in some embodiments of the present disclosure, the swing arm 12101 may include a groove 121011 for accommodating the second transmission gear 14303 and the third transmission gear 14304, or for accommodating the second transmission gear 14303, the third transmission gear 14304 and at least one intermediate transmission gear 14307. In some embodiments, the swing arm 12101 can be configured to have a groove 121011 that matches the shape of the gears to be accommodated, based on the number of gears to be accommodated, for placing the gears. In this way, not only can space be saved, but also it can be ensured that the gears can be more firmly embedded in the swing arm 12101, making the transmission more accurate and reliable, and improving the operating efficiency of the entire device. In some embodiments, a cover plate can be provided on the exposed portion of the gear on the other side of the groove to better protect the gear and make maintenance easier.

[0047] As shown in FIG3 , in some embodiments of the present disclosure, the swing arm gear 12103 is a ring gear that is mounted outside the first transmission shaft 14302 and is rotationally connected to the first transmission shaft 14302. In some embodiments, the first transmission shaft 14302 can be mounted within the swing arm bearing seat 12104 shown in FIG2 and is rotationally connected to the swing arm bearing seat 12104. The swing arm gear 12103 is mounted outside the swing arm bearing seat 12104, thereby achieving a rotational connection between the swing arm gear 12103 and the first transmission shaft 14302. In some embodiments, the first transmission shaft 14302 can be rotationally connected to the interior of the swing arm bearing seat 12104 and an intermediate member (e.g., a sleeve fixedly connected to the mounting bracket 130). The intermediate member can be mounted outside the first transmission shaft 14302 and is rotationally connected to the first transmission shaft 14302 (e.g., via a bearing), thereby achieving a rotational connection between the swing arm gear 12103 and the first transmission shaft 14302.

[0048] In some embodiments, the distal end of the first transmission shaft 14302 extends sequentially through the mounting frame 130 and the swing arm bearing seat 12104 before being fixedly connected to the second transmission gear 14303. The first transmission shaft 14302 can be rotationally connected to the mounting plate 130 via, for example, a bearing, or can be rotationally connected to an intermediate member or the swing arm bearing seat 12104. The first transmission shaft 14302 can drive the rotation of the second transmission gear 14303 while not interfering with the swinging motion of the swing arm 12101.

[0049] As shown in FIG3 , in some embodiments, the swing arm 12101 is rotatably connected to the second transmission shaft 14305. For example, the swing arm 12101 may be rotatably connected to the second transmission shaft 14305 via a bearing. In some embodiments, the third transmission gear 14304 is a ring gear that is sleeved outside the proximal end (the right side as shown in FIG3 ) of the second transmission shaft 14305 and is fixedly connected to the second transmission shaft 14305.

[0050] As shown in FIG1 , in some embodiments of the present disclosure, a sample carrier 110 may include a proximal carrier body 112, a connecting rod 113, and a distal carrier body 114. The proximal carrier body 112 is fixedly connected to the sample carrier gear 111. The proximal end of the connecting rod 113 is fixedly connected to the proximal carrier body 112. The distal carrier body 114 is fixedly connected to the distal end of the connecting rod 113 and is used to carry samples.

[0051] As shown in FIG3 , in some embodiments of the present disclosure, the vacuum sample holder 100 may further include a heating assembly 150. As shown in FIG1 and FIG2 , the heating assembly 150 is connected to the base 12102 and is disposed between the proximal frame 112 and the distal frame 114, and is used to heat the sample carried on the sample carrier 110. When the sample carrier 110 can swing, the distance between the heating assembly 150 and the sample carried by the sample carrier 110 can be ensured to be consistent, thereby improving the process control accuracy and the uniformity of heating. Moreover, when performing process operations such as coating, the sample carried on the sample carrier 110 can be rotated in-plane by the drive of the rotary transmission assembly 140, thereby further reducing the heat distribution difference caused by the heater.

[0052] FIG5 shows a schematic structural diagram of a heating assembly 150 according to some embodiments of the present disclosure.

[0053] As shown in Figures 2 and 5, in some embodiments of the present disclosure, the base 12102 may include a back plate 121021 and a front plate 121022 fixedly connected to the back plate 121021. The front plate 121022 includes a front plate through hole (not shown in the figure). As shown in Figure 5, the heating assembly 150 may include a heating device 151 and a heating device fixing member 152. The heating device 151 is arranged on the proximal side of the distal frame 114. The proximal end of the heating device fixing member 152 is fixedly connected to the back plate 121021 of the base 12102, and the distal end extends through the front plate through hole and is fixedly connected to the heating device 151. The sample rack gear 111 may include a central through hole (not shown in the figure) for allowing the heating device fixing member 152 to pass through and be rotatably connected to the heating device fixing member 152.

[0054] As shown in Figure 5, in some embodiments, the central portion of the front plate through hole in the front plate 121022 includes an annular sinking area, and the heating component 150 may further include a sleeve 153, and the sleeve 153 includes a sleeve end cover (not shown in the figure). The end cover of the sleeve 153 may include a flange, and the flange can be placed in the annular sinking area of ​​the front plate through hole. The portion of the sleeve 153 located at the distal end surface of the flange passes through the front plate through hole. The cooperation between the flange and the sinking area ensures that the sleeve 153 will not fall off from the front plate through hole. The sleeve end cover may also include an end cover through hole, and the end cover through hole can be used as a passage for some components. For example, after the heating device fixing member 152 extends through the end cover through hole, it is fixedly connected to the heating device 151. For example, in some embodiments, the sleeve 153 may include at least one fixing rod 15301, the proximal end of the at least one fixing rod 15301 being fixedly connected to the sleeve end cap, and the distal end extending through the end cap through-hole and then fixedly connected to the heating device 151, thereby further providing support and positioning for the heating device 151 and ensuring the overall stability and functionality of the heating assembly 150. As shown in Figure 5, in some embodiments, the heating device fixing member 152 includes two fixing shafts. Those skilled in the art will understand that this is merely exemplary and that the heating device fixing member 152 may also include other numbers of fixing shafts.

[0055] As shown in Figure 5, in some embodiments, the heating component 150 may also include a sleeve bearing (not shown in the figure), the outer ring of the sleeve 153 is fixedly connected to the inner ring of the sleeve bearing, and the outer ring of the sleeve bearing is fixedly connected to the center through hole of the sample carrier gear 111, thereby realizing the rotational connection between the sample carrier gear 111 and the heating device fixing part 152.

[0056] In some embodiments of the present disclosure, the heating device 151 and the sample carrier 110 can both swing simultaneously with the swinging of the swing frame 121, thereby achieving synchronized swinging of the sample and the heating device, thereby avoiding temperature differences caused by different distances between the sample (e.g., substrate) on the sample carrier 110 and the heating device 151. In some embodiments, the rotating transmission assembly 140 shown in Figure 3 can also be combined to achieve continuous rotation of the sample relative to the heating device 151 during the coating process, thereby reducing film thickness non-uniformity caused by heating non-uniformity.

[0057] FIG6 is a schematic structural diagram of a baffle of a vacuum sample holder 100 according to some embodiments of the present disclosure.

[0058] As shown in FIG6 , in some embodiments of the present disclosure, the vacuum sample holder 100 may further include a baffle 160 and a baffle drive assembly 170. The baffle 160 is disposed distally to the sample carrier 110. The baffle drive assembly 170 is connected to the baffle 160 and is configured to drive the baffle 160 to rotate. The baffle drive assembly 170 includes a baffle rotation drive shaft 171 configured to receive a rotational drive. The distal end of the baffle rotation drive shaft 171 is fixedly connected to the baffle 160, driving the baffle 160 to rotate to shield or expose the sample.

The swing drive device 300 is connected to the drive vacuum chamber 200 and to the swing transmission assembly 122 of the swing assembly 120 of the vacuum sample holder 100, and is configured to drive the swing transmission assembly 122 to cause the swing frame 121 of the swing assembly 120 to swing about a swing axis.

[0061] As shown in FIG7 , in some embodiments of the present disclosure, a swing drive device 300 may include a swing drive motor 310 and a swing drive circuit 320. The proximal end of the swing drive circuit 320 is connected to the output end of the swing drive motor 310, and the distal end is connected to the proximal end of the swing drive shaft 12201 via a gear transmission. In some embodiments, the distal end of the swing drive circuit 320 extends through the drive vacuum chamber 200 and is connected to the proximal end of the swing drive shaft 12201 as shown in FIG2 . The drive shafts in the swing drive circuit 320 may be connected in stages using at least one universal joint to ensure that power can be effectively transmitted at different angles and directions.

[0073] In some embodiments of the present disclosure, the sample carrier 110 and the heating device 151 can achieve synchronized oscillation to avoid temperature differences caused by varying distances between the sample and the heating device. The oscillating frame 121 is a non-stationary design. When using heat sources in different positions, the oscillating frame 121 swings to ensure that the beam and the sample plane on the sample carrier 110 maintain a strict 90-degree angle. Even concave bars can be adjusted to the appropriate angle during the coating process through oscillation, preventing beam obstruction and improving coating uniformity.
