Definitions
- the thick metal portion 2 is provided on the metal layer 21. It is preferable that the thickness of the metal thick portion 2 be larger than the thickness of the metal layer 21. Further, as the thickness of the metal layer 21 (h1: see FIG. 3) and the thickness of the metal thick portion 2 (h2: see FIG. 3), from the viewpoint of sufficiently transferring the heat from the light emitting element 4 to the insulating layer 1 31 to 275 ⁇ m are preferable, and 35 to 275 ⁇ m are more preferable. Further, for the same reason, the thickness of the portion included in the inside of the insulating layer 1 in the thick metal portion 2 is preferably 30 to 100% of the thickness of the insulating layer 1, and is 50 to 100%. Is more preferred.
- the manufacturing method shown in FIG. 4 acts similarly.
- the elongated metal layer 21 is drawn out from the metal layer roll body 22 and is sent out to the roll pair (30a, 30b) side.
- a long laminate 24 is drawn out from the roll 23 of the laminate 24 of the insulating layer 1 and the metal layer 5 in the B-stage state, and is delivered to the roll pair (30a, 30b) side.
- it is conveyed between the roll pair (30a, 30b), and the metal layer 21 and the laminate 24 are pressed by the roll pair (30a, 30b) to laminate the metal layer 21 and the laminate 24 together.
- a laminated body 25 is formed in a state where the thick metal portion 2 is embedded in the inside of the insulating layer 1 of the laminated body 24.
- the insulating layer 1 and the metal layer 5 are removed so that the thick metal part 2 is exposed.
- a removal apparatus a polishing means, exposure development, a chemical process etc. are mentioned as an apparatus which can expose the metal thick part 2, maintaining planarity, for example.
- only the metal layer 5 and the insulating layer 1 may be removed so that the top of the thick metal portion 2 is exposed, for example, only the metal layer 5 and the insulating layer 1 may be formed.
- the surface electrode portion 31 is formed by forming a pattern on the side where the thick metal portion 2 is exposed by etching or the like using a photolithography method.
- FIG. 5 An example using the package substrate in a state where the thick metal portion 2 manufactured by the above manufacturing method is exposed will be shown below.
- a metal pattern 51 is formed on the metal layer 21, and a mounting pad 2 e is formed on the top of the thick metal portion 2.
- the light emitting element 4 is mounted via the mounting pad 2e. From the viewpoint of heat conductivity, it is more preferable that both the mounting pad 2e and the metal thick portion 2 be joined by plating.
- the mounting pad 2 e may be omitted, and the light emitting element 4 may be bonded directly to the top of the thick metal portion 2.
- the lens 9 having a convex surface is joined to the upper surface of the sealing resin 7 to form the weir 6; however, the lens 9 and the weir 6 can be omitted. It is also possible to provide a pad on top of the metal bump.
