Abstract

An inspection device of a semiconductor device includes a socket where the semiconductor device is installed, and a measuring part configured to inspect an electrical property of the semiconductor device. A standard sample and the socket are provided in a body. A standard value of the standard sample is stored in the measuring part. Whether there is abnormality of the measuring part is determined by comparing a value of the standard sample measured by the measuring part and the standard value.

Claims (37)

1. An inspection device of a semiconductor device, comprising:

a socket where the semiconductor device is installed;

a measuring part configured to inspect an electrical property of the semiconductor device; and

a standard sample board where a standard sample is mounted;

wherein

the standard sample and the socket are provided in a body,

a standard value of the standard sample is stored in the measuring part,

the standard sample board and the socket are unified,

the standard sample board is electrically connected to the measuring part,

the standard sample board includes a relay circuit configured to electrically connect or disconnect the measuring part and the standard sample, and

whether there is abnormality of the measuring part is determined by comparing a value of the standard sample measured by the measuring part and the standard value.

2. The inspection device of the semiconductor device as claimed in claim 1 ,

wherein if relay of the relay circuit is turned on, the measuring part and the standard sample are electrically connected; and

if the relay of the relay circuit is turned off, the measuring part and the standard sample are electrically disconnected so that the measuring part is electrically connected to the semiconductor device.

3. The inspection device of the semiconductor device as claimed in claim 1 ,

wherein the standard sample board is detachably installed in the inspection device.

4. The inspection device of the semiconductor device as claimed in claim 1 ,

wherein the value of the standard sample measured by the measuring part and the standard value of the standard sample stored in the measuring part are compared by implementing an inspection program provided in the measuring part.

5. The inspection device of the semiconductor device as claimed in claim 4 ,

wherein if it is determined that there is no abnormality in the measuring part based on the comparison, a difference between the measured value of the standard sample and the standard value of the standard sample written in the inspection program is fed back to the inspection program as an error of the measuring part.

6. An inspection device of a semiconductor device, comprising:

a socket where the semiconductor device is installed;

a measuring part configured to inspect an electrical property of the semiconductor device; and

a standard sample board where a standard sample is mounted;

wherein

the standard sample and the socket are provided in a body,

a standard value of the standard sample is stored in the measuring part,

the standard sample board and the socket are unified,

whether there is abnormality of the measuring part is determined by comparing a value of the standard sample measured by the measuring part and the standard value, and

a relay board, the relay board being configured to electrically connect the semiconductor device and the standard sample, is provided between the socket where the semiconductor device is provided and the standard sample board.

7. The inspection device of the semiconductor device as claimed in claim 6 ,

wherein the relay board and the semiconductor device are connected by a socket pogo pin.

8. The inspection device of the semiconductor device as claimed in claim 7 ,

wherein the relay board and the standard sample board are connected by a standard sample board pogo pin, the standard sample board pogo pin being inserted in the standard sample board, and

the standard sample board pogo pin and the standard sample are connected by a pattern wiring formed in the standard sample board.
