Method for carrying a semiconductor device
View Patent ↗A method for carrying a semiconductor device includes: (a) providing semiconductor devices each having a main surface, a back surface, and a plurality of external terminals; (b) providing a tray having a front surface, a rear surface, an electronic tag imbedded in the tray, first concaved portions formed on the front surface, second concaved portions formed on the rear surface, the electronic tag constituted by a non-contact recognition type chip having a memory circuit in which recognizable information is stored, a depth of the first concaved portion is deeper than a depth of the second concaved portion; (c) housing the semiconductor devices into the first concaved portions respectively in such a manner that the back surface of the semiconductor device being oppose to a bottom of the first concaved portion; and (d) carrying the tray with the semiconductor devices.
1. A method for carrying a semiconductor device, comprising the steps of:
(a) providing a plurality of semiconductor devices each having a main surface, a back surface opposite to the main surface, and a plurality of external terminals;
(b) providing a tray having a front surface, a rear surface opposite to the front surface, an electronic tag imbedded in the tray, a plurality of first concaved portions formed on the front surface, a plurality of second concaved portions formed on the rear surface, the electronic tag constituted by a non-contact recognition type chip having a memory circuit in which recognizable information is stored, a depth of the first concaved portion is deeper than a depth of the second concaved portion;
(c) housing the plurality of semiconductor devices into the plurality of first concaved portions respectively in such a manner that the back surface of the semiconductor device being oppose to a bottom of the first concaved portion; and
(d) carrying the tray with the plurality of semiconductor devices.
2. The method according to claim 1 , wherein the recognizable information is related to a manufacturer's name and a product number of the tray.
3. The method according to claim 1 , wherein the semiconductor device is a semiconductor chip.
4. The method according to claim 3 , wherein, in the step (c), the semiconductor chip is accommodated in the tray in an atmosphere wherein the size of dust particle present therein is not larger than 5 μm.
5. The method according to claim 1 , wherein the semiconductor device is a semiconductor package with a semiconductor chip incorporated therein.
6. The method according to claim 5 , wherein, in the step (c), the semiconductor device is accommodated in the tray in an atmosphere wherein the size of dust particle present therein is not larger than 100 μm.
7. The method according to claim 1 , wherein each of the plurality of first concaved portions is shaped quadrangle in a plan view.
8. The method according to claim 7 , wherein the plurality of first concaved portions are partitioned with a plurality of ribs, and the ribs are not formed at a corner of the first concaved portion.
