Abstract

PURPOSE:To improve workability by arranging a sensor detecting the forming state of a metal film below a movable table, and putting a failure mark on the surface position of a semiconductor element in which a metal film is not perfectly formed. CONSTITUTION:A probe card 22 is fixedly arranged above a movable table 50 whose rear is constituted of a transparent member 51, and a needle 23 is suspended from the probe card. Electrode pads 3 on a semiconductor element 2 formed on the peripheral part of a wafer are brought, one by one, into elastic contact with the needle 23. At this time, the shape state of a metal film (m) is simultaneously detected by a sensor 6. This detected signal is inputted into a judging circuit 6, which discriminates whether the shape state of the metal film (m) is acceptable. When it is recognized that the metal film (m) is not perfectly formed, a ink marking signal is delivered to a marking apparatus 24, and a failure mark is put on the surface of the semiconductor element 2.

However, since the retaining hole (12a) is provided with a flange or claw, the metal film (rn) is not formed in the portion where the semiconductor wafer (1) is in contact with the flange or claw. For example, when the tsuba is formed, as shown in Figure 6,
The metal film (m) is not formed at the periphery of the semiconductor wafer (1). Since the edge of the peripheral part of the semiconductor wafer (1) is circular, most of the semiconductor pellets (4) are normally rectangular and are determined to be defective in the characteristic check or outer ring inspection, but the metal film is (m) may not be partially formed. However, as shown in the partially enlarged view of FIG. 6, when metal 1) 1(m) is not partially formed,
Of course, even if it is not formed at all, it is possible to conduct electricity through the metal film formed on the adjacent semiconductor element (2), so it will not necessarily be judged as a defective product in the characteristic check and will not be marked as defective. Then, even a defective semiconductor chip (4) is mounted on a lead frame or the like. Moreover, since it is visually fixed, it cannot be visually determined that the connection is defective, and since it is electrically connected, it cannot be removed during shipping inspection or the like.

The present invention also provides a method for adsorbing a semiconductor wafer on which a large number of semiconductor elements are formed and a metal film formed on the back surface on a movable table in which at least the portion that contacts the outer periphery of the semiconductor wafer is made of a light-transmitting member. In a manufacturing method, the characteristics of the device are inspected and a marking device placed above the movable table marks the surface of the defective semiconductor device. The formed state of the metal film is detected by the sensor, and the discrimination circuit electrically connected between the marking device 1 and the sensor identifies whether the formed state of the metal film is good or bad. A method for manufacturing a semiconductor device, characterized in that the surface of a semiconductor pellet is marked by the above-described marking device. [Operation] The metal film formed on the back surface of the semiconductor wafer is often formed in a defective state in the peripheral area of the semiconductor wafer, and it is possible to detect at least the state of formation of the metal film in the peripheral area of the semiconductor wafer using a sensor. do. This detection is performed at the same time as testing the characteristics of a large number of semiconductor elements formed on a semiconductor wafer.The signal output from the sensor is input to a discrimination circuit, which then identifies whether the metal film is in good condition or not. The discrimination circuit further outputs a signal to the marking device 5 to mark a semiconductor element whose metal film is recognized as defective as defective. [Example] An example of the present invention will be described with reference to FIG. However, parts that are the same as before will be given the same symbols and their explanations will be omitted. In the same figure, (50) has metal 1 on the back side! tl(m)
It is a movable table that adsorbs the semiconductor wafer (1) on which it has been formed, and moves intermittently in the horizontal and vertical directions. This movable table (50) differs from the conventional one in that at least the part that abuts the outer peripheral part (1a) of the back surface of the semiconductor wafer (1) is made of a transparent member (51) such as quartz glass (52), which is made of gold aluminium. (5) is a reflective film that reflects the same amount of light as the film (m), and is formed below the center of the movable table (50) that does not constitute the translucent member (51).
This sensor detects the state of formation of the metal film (m) and is placed below the translucent member (51) of the movable table (50), facing the marking device (24). The sensor (5) is a metal film (5), such as a COD that can detect one semiconductor element (2) at a time or a line sensor that can detect the width of one semiconductor element (2). m) is not specified as long as it can detect whether or not it is formed. Whether or not the metal film (m) is detected is determined by the difference between the amount of light reflected from Kinku 1) 1J (m) and the amount of light reflected from the part where the metal film (m) is not formed. do. (6) inputs the output signal from the sensor (5), and detects the gold Z film (m) based on the difference in light intensity.
A discrimination circuit that identifies the formation state of the metal film (m) outputs a signal to cause the marking device (24) to apply ink when the metal film (m) is not completely formed. The semiconductor manufacturing apparatus according to the present invention is configured as described above,
Next, a method for manufacturing a semiconductor device using this apparatus will be described.

As explained in the prior art, a metal film ( m >
The semiconductor wafer (1) on which is formed is placed on a movable table (
50), and the characteristics of each semiconductor element (2) are inspected. That is, a semiconductor element (2) formed on the periphery of a semiconductor wafer (1) is attached to a twenty-one dollar (23) hanging vertically from a probe card (22) fixedly arranged above a movable table (50). The upper electrode bands (3) are brought into elastic contact one by one. At this time, at the same time, the sensor (5
), gold mEl! Detect the formation state of i(m).
This detected signal is input to a discrimination circuit (6), which discriminates whether the formation state of the metal film (m) is good or bad. When it is determined that the gold film (m>) is not completely formed, a signal is output to the marking device a (24) to apply ink, and a defective mark is placed on the surface of the semiconductor element (2). In this manner, when the characteristics of one semiconductor element (2) and the formation state of the metal film (m) have been inspected, the movable table (50) is moved vertically and horizontally to remove the semiconductor on the center side. The characteristics of the element (2) are inspected.A metal film (m
) is reliably formed, and the movable table (50
) is not made of a light-transmitting member (51), the formation state of gold κIN(m) of the semiconductor element (2) on the center side is not inspected. As shown in the illustrated example, if a reflective film (52) that reflects the same amount of light as gold HI [ff(m) is formed under the movable table (50) in the center, the discrimination circuit (
6) does not identify that metal y4(m) is not formed on the semiconductor element (2). Therefore, the semiconductor element (1) on the center side of the semiconductor wafer (1) has metal 1!
No defect mark is attached due to the formation state of (m).

In this way, when the characteristics inspection and the inspection of the formation state of the metal film (m) are completed, the sample is sent to a pelletizing process and a pellet mounting process. In the pellet mounting process,
Semiconductor pellets (4) with defective characteristics or poor metal film formation, which are marked as defective, are removed by vacuum suction by a collet (42) and mounted on a lead frame or the like. The above describes one embodiment of the present invention, and the present invention is not limited to this embodiment, and the design can be changed within the gist of the present invention. For example, the entire surface of a movable table that attracts semiconductor wafers may be made of a transparent material, or reflection 1! It is not necessary to form fl (52).
