Definitions
- the present invention relates to a semiconductor device in which a semiconductor chip is mounted on a substrate by flip-chip connection, and the semiconductor chip is bonded and fixed to the substrate via bonding means.
- the flip-chip connection refers to a method of connecting the active element surface of the semiconductor chip 12 to the substrate 10 as shown in FIG. 2 (c).
- solder bumps as electrodes on the semiconductor chip 12 are used. After forming the semiconductor chip 12 and turning the semiconductor chip 12 upside down to match the mounting position of the substrate 10, the solder bumps 16 are melted and the electrodes of the semiconductor chip 12 are simultaneously connected to connection terminals (not shown) formed on the substrate 10. At the same time, the semiconductor chip 12 is fixed on the substrate 10.
- the solder bumps 16 can be arranged not only around the semiconductor chip 12 but also at any position on the semiconductor chip 12, so that a large number of input / output terminals (IZO) can be easily obtained.
- IZO input / output terminals
- the semiconductor chip 12 is directly mounted on the substrate 10 via solder as described above, the connection between the substrate 10 and the active element surface of the semiconductor chip 12 is improved in order to improve the reliability (strength, etc.) of the connection portion.
- an underfill agent (epoxy resin, etc.) 18 as an adhesive is filled in the gaps between the two to reinforce them.
- an anisotropic conductive film that functions as an adhesive in the same manner as the underfill agent, instead of the underfill agent, is attached to the substrate 10 using an anisotropic conductive adhesive.
- the semiconductor chip 12 may be connected.
- a semiconductor chip on which gold stud bumps are formed by gold wire bonding and a substrate on which an anisotropic conductive adhesive is applied or an anisotropic conductive film is mounted are prepared.
- the semiconductor chip is placed on the substrate via an anisotropic conductive adhesive or an anisotropic conductive film, and the connection between the substrate and the semiconductor chip is established by heating and pressing.
- the conductive film contains approximately 3 zm of nickel particles in an epoxy resin, and is cured by this heating in the same manner as an underfill agent.
- the conventional semiconductor device 14 described above has the following problems.
- the outer shape of the substrate 10 or the semiconductor chip 12 is obtained from a large square (rectangular or square) substrate having a predetermined dimension, which is usually called a fixed-size substrate in the case of the substrate 10, or the semiconductor chip 12.
- a large square (rectangular or square) substrate having a predetermined dimension which is usually called a fixed-size substrate in the case of the substrate 10, or the semiconductor chip 12.
- the semiconductor chips 12 are mounted on the substrate 10 such that the sides of each semiconductor chip 12 are parallel to the sides of the substrate 10. Further, in general, the semiconductor chip 12 is mounted such that the center thereof is the center of the substrate 10. refer graph1.
- the semiconductor device 14 is basically mounted on a circuit board (not shown) having a flat shape, in order to reduce the cause of poor connection between the circuit board and the board 10, Is also a flat shape It is desirable.
- connection between the substrate 10 and the semiconductor chip 12 is made up of an underfill agent 18, an anisotropic conductive adhesive, and an anisotropic conductive film, which are filled for the purpose of improving durability and reliability.
- the stretched substrate 10 contracts gradually as the temperature decreases.
- the substrate 10 on which the semiconductor chip 12 is mounted (fixed) via the filler 18 is used. (That is, the area of the substrate 10 that is in contact with the underfill agent 18).
- the amount of shrinkage of B is smaller than that of the other parts of the substrate 10 because the thermal expansion coefficient of the semiconductor chip 12 is smaller than that of the substrate 10. Less than shrinkage. Therefore, when the substrate 10 is viewed from the side, and the semiconductor chip 12 is separated into a mounting surface side and a rear surface side thereof, the mounting surface side including the region B where the semiconductor chip 12 is mounted is considered.
- the amount of shrinkage on the back side is greater than the amount of shrinkage, and as a result, the substrate 10 warps so that the back side becomes concave, as shown in FIG. 2 (c).
- the warpage of the substrate 10 that is, the warpage of the semiconductor device 14 there is the following relationship between the substrate 10 and the region B on which the semiconductor chip 12 is mounted.
- the warpage of the substrate 10 is a phenomenon that occurs because the region B of the substrate 10 in contact with the underfill agent 18 does not contract based on the original thermal expansion coefficient of the substrate 10.
- the warp occurs radially around the region B, more specifically, radially around the center point of the region B over the entire substrate 10.
- the larger the width of the region B located on the virtual straight line L the larger the amount of warpage.
- the substrate 10 is bent substantially in a U-shape around the region B as a whole, and is thus warped. Is maximum at the intersection of the virtual straight line L farthest from the region B and the outline of the substrate 10. Further, in the rectangular substrate 10, the above-described intersection portion that is farthest when the region B is the center is an intersection portion when the virtual straight line L overlaps a diagonal line of the substrate 10, that is, a corner portion. In other words, there is a relationship that the warp generated at the corners of the substrate 10 located at both ends along the diagonal is maximized.
- both the substrate 10 and the semiconductor chip 12 are square, and the semiconductor chip 12 is arranged on the substrate 10 so that each side is parallel to each other.
- the semiconductor chip 12 and the semiconductor chip 12 are mounted so that the center positions thereof coincide with each other. For this reason, since the diagonal line of the substrate 10 and the diagonal line of the semiconductor chip 12 overlap, the width of the region B on the diagonal line where the warp is the largest for the substrate 10 is the largest. In such a configuration, the amount of warpage of the substrate 10 becomes the largest. Therefore, there is a problem that the possibility that large warpage is generated at the four corners of the substrate 10 is extremely high.
- an object of the present invention is to provide a semiconductor device capable of reducing the warpage of a substrate.
- a substrate made of an insulating material having a connection terminal on a surface, and the connection terminal and an electrode are flip-chip connected and mounted on the substrate.
- a semiconductor device comprising: a semiconductor chip having the electrode; and an adhesive unit filled between the substrate and the semiconductor chip.
- Each side in the plane shape of the substrate is not parallel to any one side with respect to each side in the plane shape of the semiconductor chip, and the substrate is not parallel to a diagonal line in the plane shape of the semiconductor chip.
- a semiconductor device is provided in which the diagonal line in the planar shape does not overlap with any diagonal line.
- the width of the contact area between the bonding means and the substrate on the diagonal line where the substrate is most likely to warp is more reliable than in the conventional case where the diagonal lines of the substrate and the semiconductor chip overlap each other. narrow. Therefore, warpage at both ends of the diagonal line of the substrate, ie, at the corners can be reduced.
- the semiconductor chip and the substrate have a square or rectangular outer shape, but even in this case, each side of the substrate is any one side of the semiconductor chip. In addition, it is not parallel, and the diagonal of the substrate does not overlap with any diagonal of the semiconductor chip.
- the bonding means may be any of an underfill agent made of an epoxy resin, an anisotropic conductive adhesive, and an anisotropic conductive film having an adhesive function.
- the same warpage reduction effect can be obtained by using any of the bonding means.
