Abstract
A tray for a semiconductor device and the semiconductor device are disclosed in which the resist of the semiconductor is not easily separated from the substrate. A tray for semiconductor device has a support section formed as a pocket for carrying the semiconductor device, a pair of first protrusions formed on the opposite sides of the support section, and a pair of second protrusions formed on the opposite sides of the tray on the surface side reverse to the surface side where the support section are provided. The second protrusions are arranged in spaced relation to and in the same direction as the first protrusions. The interval between the first protrusions is larger than the interval between the second protrusions, so that in the case where the tray receives a shock, the semiconductor device comes into contact with the second protrusions earlier than with the first protrusions, thereby making it difficult for the resist of the semiconductor device to come off.
