As shown in FIG. 3, a bump 5 is formed at the tip of the finger 4, and although it is not mentioned in the cited example, the surface of the bump 5 is usually smooth.

Even if an attempt is made to bond the Fulmi pad and the finger bump by thermocompression bonding using a thermocompression layer or ultrasonic waves, the oxide film formed on the aluminum pad surface will be destroyed and removed because the bank surface in contact with the aluminum pad is smooth. However, there were problems in that the bonding was unstable and the bonding strength could not be ensured.

ており、バンプ5の表面の面粗度が大きくなっている。FIG. 1 is a cross-sectional view of a banked board according to an embodiment of the present invention, in which 1 is a substrate made of &IJ imide or glass finish, 2 is an adhesive, 3 is a conductive pattern, 4 is a finger, and 5 is a bump. . The bump 5 is formed by half-etching the middle of the finger 4, and the bank 50 is formed by half-etching the middle of the finger 4.
The surface is plated with nickel on the bottom layer and gold on the top layer to increase the roughness of the underlying surface. By the way, when bonding the aluminum pad and bank of an IC chip, the rough convex portions on the bump surface of the substrate deform while digging into the surface of the aluminum pad, destroying the oxide film on the surface of the aluminum pad and preventing the inside of the aluminum pad from being cleaned. The metal surface and the substrate bump metal form an alloy, and a strong bond can be obtained. Therefore, the surface roughness of the bump 5 has a large effect on the bonding strength, and the rougher the surface roughness, the greater the bonding strength, and as described later, the maximum surface roughness (hereinafter referred to as Rm5LX) is 5 to 20 μm.
It is desirable that the surface condition of the bump at this time be satin-like or streaky. The back surface of the copper foil, which will become the front surface, is roughened by precipitated particles of electrolytic steel plating during copper foil manufacturing to increase the layer density with the base material 1 via the adhesive 2, and the surface roughness is Rma.
w The corner is approximately 5 to 12μ. However, this is reduced to about Rm & 13~8μm by going through the manufacturing process of the bumped board such as surface treatment and etching.Here, by utilizing the fact that the current concentrates at the tip, 1!L plating is applied to the lower layer. By plating nickel and gold on the upper layer, the minute protrusions on the bump surface are increased. Figure 8g2 is an enlarged cross-sectional view of the bump part, and the surface of the steel foil 6 is plated with nickel 8 and gold 9. Since the current is concentrated on the bump 7, the thickness is thick at the bump 7 and thinner around the bump 7, and the surface roughness of the bump 5 is increased.

μ shoulder, Rm&! on the bump surface! The surface roughness was enlarged by 2 to 6 μm in IS-. Note that this varies depending on the plating apparatus and plating solution mentioned above, but in order to obtain the same plating thickness, it is possible to obtain a large surface roughness by plating near the upper limit of the allowable current density and plating for a short time.

This shows the data for Rushi.

The m1 joint strength is the strength when the joint or finger breaks when the center of the finger is pulled vertically upward. As can be seen from Table 1, when the current density is 2.5 A/- or less, the higher the current density, the greater the surface roughness and the higher the bonding strength. In particular, stable bonding is obtained when the total surface roughness is Rwax 5 μm or more, and when the surface roughness of the substrate is small, it is particularly effective to increase the surface roughness by plating. On the other hand, when the surface roughness of @ foil is Rm & 115 μm, the steel foil becomes rough and there is a tendency for the finger strength to decrease.

Rmax 20μm以下であることが望ましく、従って
トータルの面粗度の適正値はR1ax5〜20 p a
である。When considering the appropriate value for the gold plating thickness, it is desirable that the total surface roughness is Rmax 20 μm or less, and therefore the appropriate value for the total surface roughness is R1ax 5 to 20 pa
It is.

を得ることが可能である。The above example is a case in which bumps are formed on the back side of electrolytic steel foil, which originally has a large surface roughness. If the surface is to be used, first roughen the surface mechanically by brush polishing or sandblasting, or chemically roughen the surface using an aqueous solution of ammonium persulfate, sodium persulfate, etc., and then expand the surface roughness by plating. For example, it is possible to obtain a bumped substrate with stable bonding, similar to when bumps are formed on the back surface of IPN copper foil.

Note that the bump 5 of the finger 4 may be provided in the opposite direction to the base material 1, and the pad of the chip C may be bonded to the bump 5, contrary to the location of the chip 0 shown in FIG. good.

This has the effect of easily destroying the oxide film on the aluminum hat, and significantly increasing the bonding strength and stability between the bumps on the substrate and the aluminum pads on the C-chip.
