This application claims priority under 35 U.S.C. 119 from Korean Patent Application No. 10-2023-0082693, filed on Jun. 27, 2023 in the Korean Intellectual Property Office, the contents of which are herein incorporated by reference in their entirety.
The present disclosure relates to a semiconductor transfer device.
Semiconductor transfer containers may transfer wafers. The wafers may have various sizes depending on their use purposes. Accordingly, semiconductor transfer containers may also have various sizes.
Semiconductor transfer devices may accommodate semiconductor transfer containers having different sizes. The semiconductor transfer device may take out wafers from the semiconductor transfer containers accommodated in the semiconductor transfer device and sort or merge the wafers. However, one semiconductor transfer device may accommodate only one semiconductor transfer container, which is inefficient. Accordingly, it is desirable to develop a semiconductor transfer device for increasing efficiency of a semiconductor transfer process.
Aspects of the present disclosure provide a semiconductor transfer device capable of improving efficiency by accommodating various semiconductor transfer containers.
However, aspects of the present disclosure are not restricted to those set forth herein.

In other words, the first bracket 211 may move in the fourth direction −X opposite to the first direction X.
The first bracket 211 is connected to the first adsorption part 171 by the first connection member 231. Accordingly, when the first bracket 211 becomes distant from the second surface, the first adsorption part 171 may also move in the direction in which it becomes distant from the second surface of the vertical extension part 110. In other words, the first adsorption part 171 may also move in the fourth direction −X.
Conversely, when the first piston 221_P and the first slope part 221_S move downward, the first bracket 211 may not be pushed by the first slope part 221_S. Since the first bracket 211 may have the property that it moves in the first direction X by the elastic material, the first bracket 211 may move in the first direction X.
Since the first bracket 211 is connected to the first adsorption part 171 by the first connection member 231, the first bracket 211 may move in the first direction X.

When the second vertical cylinder 222 is moved in the downward direction, the second piston 222_P and the second slope part 222_S may move downward. Conversely, when the second vertical cylinder 222 is moved in the upward direction, the second piston 222_P and the second slope part 222_S may move upward.
The second bracket 212 may have a property that it moves in the first direction X from the second surface toward the first surface by an elastic material or biasing member.
When the second piston 222_P and the second slope part 222_S move downward, the second bracket 212 may be in contact with a second curved surface C2 of the second slope part 222_S. When the second piston 222_P and the second slope part 222_S further move downward, the second bracket 212 may be pushed in a direction in which it becomes distant from the second surface of the vertical extension part 110 by the second slope part 222_S. Accordingly, the second bracket 212 may move in the direction in which it becomes distant from the second surface of the vertical extension part 110. In other words, the second bracket 212 may move in the fourth direction −X opposite to the first direction X.
The second bracket 212 is connected to the second adsorption part 172 by the second connection member 232. Accordingly, when the second bracket 212 becomes distant from the second surface of the vertical extension part 110, the second adsorption part 172 may also move in the direction in which it becomes distant from the second surface. In other words, the second adsorption part 172 may also move in the fourth direction −X.
Conversely, when the second piston 222_P and the second slope part 222_S move upward, the second bracket 212 may not be pushed by the second slope part 222_S. Since the second bracket 212 may have the property that it moves in the first direction X by the clastic material, the second bracket 212 may move in the first direction X.
Since the second bracket 212 is connected to the second adsorption part 172 by the second connection member 232, the second bracket 212 may move in the first direction X.
In order to move the first adsorption part 171 or the second adsorption part 172 in the first direction X or the fourth direction −X, a cylinder extending in the first direction X may be used. However, when the cylinder extending in the first direction X is used, the cylinder extending in the first direction X may interfere with a structure positioned on the second surface of the vertical extension part 110. For example, a transport robot gripping and transporting a wafer may exist on the second surface of the vertical extension part 110. When the cylinder extending in the first direction X is used, interference may occur between the cylinder extending in the first direction X and the transport robot.

A fourth-type guide part 154 may penetrate through the horizontal plate 140. The fourth-type guide part 154 may be movable within a predetermined range in the third direction Z. In other words, the fourth-type guide part 154 may move up and down within a predetermined range. The fourth-type guide part 154 may receive power provided by the first guide cylinder 161.
The fourth-type guide part 154 may be spaced apart from the first-type guide part 151 in the first direction X. In other words, the fourth-type guide part 154 may be spaced apart from the first-type guide part 151 in the fourth direction −X opposite to the first direction X.
The first-type guide part 151 and the third-type guide part 153 may be spaced apart from each other in opposite directions based on the fourth-type guide part 154. In other words, the fourth-type guide part 154 may be positioned between the first-type guide part 151 and the third-type guide part 153.
The fourth-type guide part 154 may have a pillar shape, and include a concave surface 154_S, a second vertical surface 154_V, and a second connection surface 154_C.
The concave surface 154_S may have a concave shape. The concave surface 154_S may be a surface formed by concavely recessing one surface of a triangular prism shape. The concave surface 154_S is a concavely recessed surface, and may be a curved surface.
The second vertical surface 154_V may be a surface parallel to the third surface of the horizontal extension part 130.
The second connection surface 154_C may be a surface parallel to the upper surface of the horizontal plate 140. The concave surface 154_S may share one edge with the second connection surface 154_C, and the second vertical surface 154_V may share the other edge with the second connection surface 154_C. Consequently, the concave surface 154_S and the second vertical surface 154_V may be connected to each other through the second connection surface 154_C.
The semiconductor transfer container 300 may be seated on the horizontal plate 140 by sliding along the concave surface 154_S.
When the concave surface 154_S is used, impact transmitted to the semiconductor transfer container 300 during a process in which the semiconductor transfer container 300 slides along the concave surface 154_S may be decreased.
