    Abstract: Disclosed is a chip substrate. The chip substrate includes: conductive portions laminated in one direction to constitute the chip substrate; insulation portions alternately laminated with the conductive portions to electrically isolate the conductive portions; a cavity formed at a predetermined depth in a recessed shape in a region including the insulation portions on an upper surface of the chip substrate; and a groove portion disposed outside the cavity in a spaced-apart relationship with the cavity and formed at a predetermined depth in a recessed shape. According to the present invention, an adhesive agent is applied in a groove portion formed in advance. It is therefore possible to prevent the adhesive agent from being exposed to the light emitted from optical elements and to prevent the adhesive agent from being denatured. This makes it possible to enhance the reliability of lens bonding. Furthermore, there is no need to use an expensive resistant adhesive agent. An existing typical adhesive agent may be used as it is. This provides an effect of saving costs. Thus, there is an advantage in that a low-priced existing bonding material may be applied to a high-priced UV-C (deep-UV) package.

    Abstract: Provided is a method of mounting a chip. The method includes: forming a bump at one surface of a cavity formed concavely in an inner direction of a substrate; performing a coining process to flatten a surface of the bump; coating a solder material on the bump subjected to the coining process; and bonding a chip and the bump by melting the solder material, wherein an electrode portion or a metal portion is formed on a bottom of the chip. For a metal substrate according to the present invention, wherein a vertical insulating layer is included, since the electrode portion of the chip and the electrode portion of the substrate have to be electrically connected, the metal substrate is bonded to the electrode portion of the chip using the bump additionally formed on the metal substrate, so the heat generated in the chip can be rapidly transferred to the substrate, and the junction temperature of the chip can be decreased, thereby enhancing the light efficiency and the. In addition, cracking due to the difference of thermal expansion coefficient between solder materials can be prevented by sealing the bonding portion of the chip using the solder materials. Further, since oxidation of the bonding portion is prevented by blocking the contact with the outside, the chip packaging process can be performed without an additional process of filling an inert gas into the internal space wherein the chip is mounted.

In the above-described structure, the coupling holes are threaded, and the coupling projections are also threaded so as to be screw-coupled to the coupling holes. The coupling holes are formed having a downwardly narrowing taper, and the coupling projections are formed having a downwardly narrowing taper so as to be precisely coupled with the coupling holes even when in a contracted state under sub-freezing temperatures. The surfaces of the heat dissipating rods are characterized in that insulation coating layers are formed thereon and not on the coupling projections. A portion of the insulation coating layers on some of the heat dissipating rods may be removed to function as electrodes.
