Abstract:
PURPOSE: A semiconductor package and a manufacturing method thereof are provided to easily perpendicularly laminate semiconductor chips in which width is different by separating first semiconductor chips after mounting second semiconductor ships having small width on a substrate in which the first semiconductor chips are formed. CONSTITUTION: A first semiconductor chip(110) is mounted on a circuit board(10). A second semiconductor chip(120) is formed on the first semiconductor chip. A first under-fill(150) covers an interval between the first semiconductor chip and the second semiconductor chip, and a side of the first semiconductor chip. An interval between the first semiconductor chip and the circuit board is filled with a second under-fill(160). A first connection pattern(130) electrically connects the circuit board to the first semiconductor chip. A second connection pattern(140) electrically connects the first semiconductor chip to the second semiconductor chip.

PURPOSE: A junction structure and method for heterogeneous substrates are provided to improve electrical characteristics by making electrically good connection of the heterogeneous substrates. CONSTITUTION: A first substrate(100) includes an electrode pad. A second substrate is bonded with the first substrate while a bonding layer is interposed. The second substrate comprises via holes(120, 130) exposing an electrode pad through the first substrate and the bonding layer. Connecting electrodes(520, 530) connect the electrode pad in the via hole. An insulating layer(400) electrically insulates a connection electrode from the second substrate. The first and second substrates have different thermal expansion coefficients. The bonding layer and the insulating layer include an organic material.
Abstract:
PURPOSE: A method for forming a semiconductor device is provided to prevent a chip-crack of the semiconductor substrate by forming a groove in a scribe lane when a through hole is formed. CONSTITUTION: A semiconductor substrate(11) includes chips and a scribe lane between the chips. A groove(45G) with a first depth is formed in the scribe lane. A through hole(45T) with a second depth is formed via the chips. The chips are separated along the groove. The second depth is deeper than the first depth.
