Abstract:
A chip substrate includes laminated conductive portions, and laminated insulation portions that electrically isolate the conductive portions, with a cavity in a recessed shape in a region including the insulation portions on an upper surface of the chip substrate. The substrate includes an insulation layer on the upper surface, excluding a region of the cavity, and a continuous plating layer along a periphery of the chip substrate on the insulation layer. A portion of a top surface of each insulation portion is exposed in the cavity, and another portion of the top surface of each insulation portion is coated with the insulation layer. A chip package includes a chip substrate, with an optical element sealed in the cavity by a sealing member or lens.
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:
Disclosed is a chip-mounting substrate. The chip-mounting substrate includes a plurality of conductive portions configured to apply voltages to at least two or more chips to be mounted, a plurality of insulation portions formed between the conductive portions and configured to electrically isolate the conductive portions, and a cavity formed in a region which includes at least three or more of the conductive portions and at least two or more of the insulation portions and depressed inward to form a space in which the chips are mounted.
