Example embodiments relate to a module tray for a semiconductor device. More particularly, example embodiments relate to a module tray for a semiconductor device for accommodating a plurality of semiconductor substrates.

2. Description of the Related Art

A module tray may be used to store and transport a plurality of semiconductor substrates. Since an inner space of the module tray is relatively narrow, it may happen that the semiconductor substrate is not inserted into a desired (or alternatively, preset) slot while a worker inserts the semiconductor substrate into the slot inside the module tray. When the semiconductor substrate is inserted into a slot other than the desired (or alternatively, preset) slot the semiconductor substrate may be damaged.

SUMMARY

Example embodiments provide a module tray for a semiconductor device capable of safely and easily accommodating a semiconductor substrate in a desired (or alternatively, predetermined) position.

According to some example embodiments, a module tray for a semiconductor device includes a case and an insert block. The case includes a base plate, first and second sidewalls extending from opposite sides of the base plate in a vertical direction to define an accommodation space, and first and second fastening grooves respectively formed in inner surfaces of the first and second sidewalls and extending in the vertical direction. The first and second fastening grooves have upper ends opened to upper surfaces of the first and second sidewalls, respectively. The insert block has a substrate accommodating space for accommodating a semiconductor substrate. The insert block is detachably inserted into the first and second fastening grooves of the case. The insert block has first and second fastening joints extending in the vertical direction such that the first and second fastening joint are respectively inserted through the upper ends of the first and second fastening grooves.

According to some example embodiments, a module tray for a semiconductor device includes a case and an insert block. The case includes a base plate, first and second sidewalls, a plurality of first fastening grooves, and a plurality of second fastening grooves. The first and second sidewalls face each other in a first horizontal direction on the base plate and defining an accommodation space. The plurality of first fastening grooves space apart from each other in a second horizontal direction orthogonal to the first horizontal direction on an inner surface of the first sidewall and respectively having first upper ends opened in a vertical direction. The plurality of second fastening grooves space apart from each other in the second horizontal direction on an inner surface of the second side wall and respectively having opened second upper ends. The insert block configures to accommodate a semiconductor substrate that is inserted therein. The insert block has first and second fastening joints that have shapes corresponding to the first and second fastening grooves such that the first and second fastening joints are respectively inserted into and engaged with the first and second fastening grooves in the vertical direction.

According to some example embodiments, a module tray for a semiconductor device includes a case and an insert block. The case has a base plate, first and second sidewalls, and first and second fastening grooves. The first and second sidewalls extend in a vertical direction from opposite sides of the base plate to define an accommodation space. The first and second fastening grooves are formed to respectively extend in the vertical direction on inner surfaces of the first and second sidewalls. The first and second fastening grooves have upper ends respectively opened to upper surfaces of the first and second sidewalls. The insert block has a substrate accommodating space for accommodating a semiconductor substrate. The insert block is detachably inserted into the first and second fastening grooves of the case. The insert block has first and second fastening joints extending in the vertical direction such that the first and second fastening joint are respectively inserted through the upper ends of the first and second fastening grooves. The insert block has a plurality of holders, each of the plurality of block holders respectively extending in the vertical direction from one of the first and second fastening joints and a pair of side protrusions configured to press and fix the semiconductor substrate inserted and accommodated into the substrate accommodating space.

Thus, the semiconductor substrate may be accommodated in the case while being inserted into the insert block. Because the first and second fastening joints of the insert block are respectively inserted into and coupled to the first and second fastening grooves of the case, the insert block may be disposed at a desired (or alternatively, predetermined) position inside the case. Because the semiconductor substrate is accommodated in the insert block, it is possible to prevent or hinder the semiconductor substrate from being inserted into a wrong position inside the case. In addition, because the semiconductor substrate is doubly protected by the insert block and the case, the semiconductor substrate can be more stably protected and managed.

As illustrated inFIG.10, the tension T provided to the holders300may be transmitted to the case100. The first and second fastening joints220,230of the insert block200may be respectively separated from the first and second fastening grooves122,132by the tension T. The case100may be fixed by an external device, a support, or the like in a process in which the insert block200is separated from the case100. For example, the tension T may be provided by the operator or the robot.

The semiconductor substrate20provided in the substrate accommodating space S2of the insert block200separated from the case100may be separated from the insert block200, and the semiconductor substrate20may be safely stored and moved by the insert block200and the case100.

As described above, the semiconductor substrate20may be accommodated in the case100while being inserted into the insert block200. Since the first and second fastening joints220,230of the insert block200are respectively inserted into and respectively coupled to the first and second fastening grooves122,132of the case100, the insert block200may be disposed at a desired (or alternatively, predetermined) position inside the case100. Since the semiconductor substrate20is accommodated in the insert block200, it is possible to prevent or hinder the semiconductor substrate20from being inserted into the case100at an incorrect position. In addition, since the semiconductor substrate20is doubly protected by the insert block200and the case100, the semiconductor substrate20may be more stably protected and managed.
