Abstract

Abstract The present invention relates to a chip-size package (CSP) semiconductor, which comprises a chip having a bonding pad formed at the center portion thereof; a substrate for seating and mounting the chip thereon, which has a predetermined shaped slot formed at the center portion thereof and is formed with a signal circuit pattern on, at least, one surface thereof; an adhesive means inserted between the chip and the substrate for attaching and fixing the chip to the upper surface of the substrate so that the bonding pad of the chip may arrange above the slot; a support and protection means for protecting and supporting the chip and the substrate; and the bonding pad of the chip and the signal circuit pattern of the substrate are electrically interconnected by wire, thus forming internal circuit, thus mass-producing at low price, easily radiated its heat occurring during the operation, thus extending its durability, and improving a reliance of the package and shortening the length of the process.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 162 words
A chip-size package semiconductor, comprising: a chip having a bonding pad formed at the center portion thereof; a substrate for seating and mounting the chip thereon, which has a predetermined shaped slot formed at the center portion thereof and is formed with a signal circuit pattern on, at least, one surface thereof, wherein the substrate is made of a ceramic plate member having a predetermined size and shape; adhesive means inserted between the chip and the substrate for attaching and fixing the chip to the upper surface of the substrate so that the bonding pad of the chip arranges above the slot; support and protection means for protecting and supporting the chip and the substrate; and a plurality of ball members for forming an external circuit, which are mounted on the circuit pattern of the substrate, wherein the bonding pad of the chip and the signal circuit pattern of the substrate are electrically interconnected by wires to thereby form an internal circuit.
Claim 2
Dependent Claim 162 words
A chip-size package semiconductor, comprising: a chip having a bonding pad formed at the center portion thereof; a substrate for seating and mounting the chip thereon, which has a predetermined shaped slot formed at the center portion thereof and is formed with a signal circuit pattern on, at least, one surface thereof, wherein the substrate is made of a ceramic plate member having a predetermined size and shape; adhesive means inserted between the chip and the substrate for attaching and fixing the chip to the upper surface of the substrate so that the bonding pad of the chip arranges above the slot; support and protection means for protecting and supporting the chip and the substrate; and a plurality of ball members for forming an external circuit, which are mounted on the circuit pattern of the substrate, wherein the bonding pad of the chip and the signal circuit pattern of the substrate are electrically interconnected by wires to thereby form an internal circuit.
Claim 3
Dependent Claim 51 words
The chip-size package semiconductor according to claim 1, wherein the signal circuit pattern includes a plurality of a wire bonding portions where each wire led from the chip is connected and a plurality of ball mounting portions where each ball member is seated on each conductive line of the signal circuit.
Claim 4
Dependent Claim 40 words
The chip-size package semiconductor according to claim 1, wherein the support and protection means is formed by injecting and filling resin for coating between the chip and the substrate by a capillarity and then curing the filled resin by heat-treatment.
