Tray for transporting semiconductor device and tray system comprising the same
A tray for transporting a semiconductor device includes a plate, a loading portion on the plate and configured to support the semiconductor device, and a sidewall portion on the plate and surrounding at least a portion of the loading portion, wherein the sidewall portion includes a first sidewall, and the first sidewall includes a first inclined portion extending from the loading portion and defining a first angle with respect to an upper surface of the loading portion, and a first guide portion extending from the first inclined portion and defining a second angle with respect to the upper surface of the loading portion, the second angle being smaller than the first angle, and the first angle and the second angle are acute angles.
1 . A tray for transporting a semiconductor device, the tray comprising:
a plate;
a loading portion on the plate and configured to support the semiconductor device; and
a sidewall portion on the plate and surrounding at least a portion of the loading portion,
wherein the sidewall portion includes a first sidewall, and
wherein the first sidewall includes:
a first inclined portion extending from the loading portion and defining a first angle with respect to an upper surface of the loading portion and configured to support an outer sidewall of the semiconductor device; and
a first guide portion extending from the first inclined portion and defining a second angle with respect to the upper surface of the loading portion, the second angle being smaller than the first angle,
wherein the first angle and the second angle are acute angles, and
wherein: the first sidewall is on a first side of the plate,
the sidewall portion further includes a fourth sidewall on the first side of the plate and spaced apart from the first sidewall,
the fourth sidewall includes a fourth inclined portion extending from the loading portion and defining the first angle with respect to the upper surface of the loading portion, and a fourth guide portion extending from the fourth inclined portion and defining the second angle with respect to the upper surface of the loading portion, and
the loading portion includes an empty space or recess between a portion connected to the first inclined portion and a portion connected to the fourth inclined portion.
2 . The tray of claim 1 , wherein the plate extends in a first direction (Y), and a length of the first sidewall in the first direction (Y) and a length of the fourth sidewall in the first direction (Y) are different from each other.
3 . The tray of claim 1 , wherein: the sidewall portion further includes a fifth sidewall on a second side of the plate facing the first side,
the fifth sidewall includes a fifth inclined portion extending from the loading portion and defining the first angle with respect to the upper surface of the loading portion, and a fifth guide portion extending from the fifth inclined portion and defining the second angle with respect to the upper surface of the loading portion.
4 . The tray of claim 3 , wherein the plate extends in a first direction (Y), and a length of the first sidewall in the first direction (Y) and a length of the fifth sidewall in the first direction (Y) are different from each other.
5 . The tray of claim 3 , wherein: the sidewall portion further includes a sixth sidewall on the second side of the plate and spaced apart from the fifth sidewall,
the sixth sidewall includes a sixth inclined portion extending from the loading portion and defining the first angle with respect to the upper surface of the loading portion, and a fifth sixth guide portion extending from the sixth inclined portion and defining the second angle with respect to the upper surface of the loading portion,
the loading portion includes an empty space or recess between a portion connected to the fifth inclined portion and a portion connected to the sixth inclined portion, and
a length of the first sidewall in a first direction (Y) and a length of the sixth sidewall in the first direction (Y) are equal.
6 . The tray of claim 1 , wherein a portion connecting the first inclined portion with the first guide portion includes a curved surface.
7 . The tray of claim 1 , wherein the loading portion comprises a plurality of spaced apart teeth at an inner surface of the loading portion and extending away from the sidewall portion.
