Tray for semiconductor integrated circuit devices

A tray for semiconductor integrated circuit devices, said tray comprising:

• a plurality of first partition walls extending in a first direction;
• each of said first partition walls comprising a pair of partition walls;
• a plurality of second partition walls extending in a second direction at right angels with the first direction;
• each of said second partition walls comprising a pair of partition walls;
• circumferential frame portions connecting end portions of said first and second partition walls;
• a plurality of first opening portions;
• and a plurality of second opening portions,
• wherein regions surrounded by said first partition walls and said second partition walls constitute seating portions for seating semiconductor integrated circuit devices,
• said first partition walls are disposed such that one of said first partition walls is disposed between two rows of the seating portions which are adjacent to each other in the second direction,
• each of the first opening portions is formed in a region surrounded by one of the pairs of partition walls constituting one of said first partition walls, and two second partition walls,
• said second partition walls are disposed such that one of said second partition walls is disposed between two rows of the seating portions which are adjacent to each other in the first direction, and
• each of the second opening portions is formed in a region surrounded by one of the pairs of partition walls constituting one of said second partition walls, and two first partition walls.
