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 semiconductor package and a manufacturing method thereof are provided to prevent a warpage by including an aluminum oxide template. CONSTITUTION: A substrate includes a first surface and a second surface which face each other. A first ground pattern(17bc,17bl) is arranged on the first surface. A second ground pattern(15bc,15bl) is arranged on the second surface. Ground vias(11b) connects the first ground pattern to the second ground pattern. A first aluminum oxide layer is interposed between the ground vias.

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.
Abstract:
PURPOSE: A semiconductor package, a substrate for the same, a circuit board system, a semiconductor module, an electronic system, and formation methods thereof are provided to improve an integration degree of a semiconductor chip by reducing an interval and a pitch between input/output pads. CONSTITUTION: A bare substrate includes a bump land(111) which is exposed on one side of the bare substrate. A bump adhesion part(147) is formed on the exposed bump land. A metal post(157) is electrically connected to the bump land. A chip pad is exposed on one side of a semiconductor chip. The metal post and the chip pad are electrically connected to each other.
Abstract:
PURPOSE: A semiconductor device and a manufacturing method thereof are provided to improve electrical properties by including a through-electrode structure which includes a plurality of insulating films. CONSTITUTION: An insulating film of a laminated structure is arranged on a sidewall of an opening part which penetrates a substrate(10). The insulating film of the laminated structure includes one or more films among a first insulating film(22s) and a second insulating film(22p). The second insulating film has lower permittivity than the first insulating film. The second insulating film is made of polymers. One insulating film selected among the first and second insulating films is arranged between the sidewall of the opening part and the other insulating film.
