If there is a defective product, a mark is attached to it, and after the dicing process, the chips with this mark are removed. This marking is generally done by applying identification ink to the chip surface. FIG. 4 shows a conventional identification ink adhesion test. An ink tube 2 for storing identification ink is attached to the support member 1, and an ink introduction tube 3 is attached to the bottom of the ink tube 2. The ink is guided from the ink tube 2 to the ink introduction tube 3. A marking needle 4 is inserted into the ink introduction tube 3 and reciprocates in the longitudinal direction within the ink introduction tube. The figure shows a state in which the tip of the mark needle 4 protrudes from the tip of the ink introduction tube 3. This marking needle 4 is generally made of a needle. The support member 1 is provided with a solenoid 5, which has a width of about 3Qms and a voltage of 24V.
By applying a certain amount of pulse, the mark needle 4 instantaneously moves back and forth, and the identification ink is deposited on the target object. FIG. 5 shows the state at the moment when the identification ink is applied to the surface of a semiconductor wafer 6 as a target object.

Conventional identification ink deposition devices suffer from ink dripping. That is, as shown in FIG. 6, an ink pool 7 is formed at the tip of the ink introduction tube 3 and falls onto the surface of the semiconductor wafer 6. Generally, a fixed card 8 as shown in FIG. 7 is provided around the identification ink deposition device, and when the semiconductor wafer 6 moves, the dripped ink 9 is removed from the fixed card 8 as shown in FIG. 8 and further spreads over the surface of the semiconductor wafer 6. After cleaning the semiconductor wafer 6 that has become contaminated in this way, it must be subjected to measurement and inspection again.

Moreover, if the drip is detected late, the dirt may spread throughout the loft due to contact between semiconductor wafers. Furthermore, since dirt adheres to the fixed card 8, the fixed card 8 must be removed and cleaned in order to continue the subsequent steps. When such dripping of ink occurs, a great deal of effort and time is required to deal with it.
