摘要： A method for filling multi-layer chip-stacked gaps is revealed, primarily comprising the steps as below. Firstly, a chip-stacked assembly is provided, comprising a substrate and a plurality of chips vertically stacked on the substrate where at least a first underfilling gap is formed between each two adjacent ones of the stacked chips with a height difference from the substrate. Then, the chip-stacked assembly is flipped and dipped into an underfilling material where the underfilling material is disposed in a storage tank in a flowing state to completely fill the first underfilling gap. Then, the chip-stacked assembly is taken out. Finally, the chip-stacked assembly is heated to cure the underfilling material filled in the first underfilling gap. Accordingly, multi-layer chip-stacked gaps with different heights can be simultaneously filled at one single step. The conventional underfilling difficulty of multi-layer chip-stacked gaps can be solved leading to higher productivity.

摘要： A semiconductor package having chip using copper process is revealed. A chip using copper process is disposed on a substrate. The substrate has a core layer, a copper circuitry with connecting pads, a patterned diffusion barrier, and a solder mask. The copper circuitry is formed on the core layer. The patterned diffusion barrier has such a pattern identical to the one of the copper circuitry that an upper surface of the copper circuitry is completely covered. The substrate further has a bonding layer formed on a portion of the patterned diffusion barrier inside the solder mask's opening. Therefore, diffusion of copper ions from the copper circuitry of the substrate to the active surface of the chip can be avoided to prevent function failure of the chip.

摘要： A substrate for multi-chip stacking and a multi-chip stack package utilizing the substrate and its applications are disclosed. The substrate comprises a first wire-bonding finger, a second wire-bonding finger, a trace configured for electrical transmission and a loop wiring on a same surface. The first wire-bonding finger and the second wire-bonding finger are adjacent each other and to a die-attaching area of the substrate. The loop wiring connects the first wire-bonding finger with the second wire-bonding finger in series and connected to the trace. The loop wiring can be selectively broken or not when at least two chips are stacked on the die-attaching area and electrically connected to the first and second wire-bonding fingers respectively. Accordingly, the chips can operate respectively and independently without mutual interference if one of the chips is fail. Moreover, there is merit to apply the multi-chip stack package utilizing the substrate because it can be repaired after molding and without removing any bonding wire during semiconductor packaging processes.

摘要： A stackable bare-die package primarily comprises a substrate, a chip, a plurality of bonding wires and an encapsulant. The substrate has a slot where a step is formed inside the slot where a plurality of inner fingers are disposed on the step. A plurality of outer pads are disposed on the bottom surface and a plurality of transfer pads on the top surface. The chip is disposed on the top surface and is electrically connected to the inner fingers by a plurality of bonding wires passing through the slot. An encapsulant is formed inside the slot to encapsulate the bonding wires. There is a height difference between the step and the bottom surface so that the loop height of the bonding wires will not exceed the bottom surface. Therefore, when stacking the stackable bare-die packages, the exposed back surface of the chip will not be touched nor stressed to avoid die crack issues.

摘要： A metal post chip connecting device without soldering materials is revealed, primarily comprising a chip and a substrate. A plurality of metal pillars are disposed on and extruded from a surface of the chip where each metal pillar has an end surface and two corresponding parallel sidewalls. The substrate has an upper surface and a plurality of bonding pads disposed on the upper surface where each bonding pad has a concaved bottom surface and two corresponding concaved sidewalls. The chip is bonded onto the upper surface of the substrate through heat, pressure, and ultrasonic power so that the end surfaces of the metal pillars self-solder to the concaved bottom surfaces and two parallel sidewalls of the metal pillars partially self-solder to two concaved sidewalls to form U-shape cross-sections of metal bonding between the metal pillars and the bonding pads. Therefore, there is no need for the conventional solder paste as chip connection to increase conductivity of the soldering points, especially, to save the soldering cost for MPS-C2 products and to greatly enhance the bonding strength of the soldering points. The manufacturing method of the above described metal post chip connecting device is also revealed.

摘要： Disclosed is a flip chip package maintaining alignment during soldering, primarily comprising a chip and a substrate. A plurality of bumps and at least an extruded alignment key are disposed on the active surface of the chip. The substrate has a plurality of bonding pads and at least an alignment base where the alignment base has a concaved alignment pattern corresponding to the extruded alignment key. When the chip is disposed on the substrate, the extruded alignment key is embedded into the concaved alignment pattern to achieve accurately align the bumps to the corresponding bonding pads. Therefore, even with the mechanical misalignment due to the accuracy of flip-chip die bonders and the transportation during reflow processes, the bumps of a chip still can accurately align to the bonding pads of the substrate to achieve accurate soldering which is especially beneficial to the mass production of MPS-C2 products.

摘要： A disclosed semiconductor device having MPS-C2 (Metal Post Solder-Chip Connection) structure can be mounted on a PCB by an SMT mounter. A chip is disposed on a substrate. The substrate has a plurality of connecting pads and a plurality of accessory pads, and the chip has a plurality of corresponding metal posts and a plurality of accessory bumps. The dimensions on the soldered flat tops of the accessory bumps are corresponding to the soldered areas of the accessory pads where each soldered flat top has a plurality of angular corners and an edge between two adjacent angular corners where the length of the edge is twice greater than the pad pitch. Therefore, the displaced or rotational displaced metal posts can be pulled back and self-aligned during reflow processes so that an SMT mounter with poor alignment accuracy can be implemented for flip-chip bonding the semiconductor device having MPS-C2 structure to replace the conventional expensive flip-chip die bonder and to achieve higher productivity. Furthermore, the shape of the flat top surfaces of the metal posts does not have to match with the shape of the connecting pads.

摘要： A wafer structure with conductive bumps and fabrication method thereof are disclosed herein. Conductive bumps are later converted into conductive balls. A central area and a marginal area are defined on the wafer. To achieve heights among conductive balls formed on the wafer structure, the sizes (can be but not limited to one) of under bump metallurgy (UBM) layer blocks in the central area are smaller than that in the marginal area. The fabrication procedure for forming under bump metallurgy layer blocks of different size includes depositing a photoresist layer on the metallurgy layer and pattern the photoresist with a photomask of smaller opening area for the central area than for the marginal area, and removing the photoresist layer and the portion of metallurgy layer under the photoresist layer.

摘要： A universal substrate includes a plurality of inner pads and a plurality of outer pads. A plurality of bifurcate wirings and a plurality of fuses are formed on a surface of the substrate. The fuses are connected with the bifurcate wirings in series. By the bifurcate wirings and the fuses, each of the inner pads is electrically connected to all of the outer pads to provide optional electrical disconnections therebetween. Accordingly, the universal substrate can provide for various chips with different serial arrangements of bonding pads without replacing or manufacturing another kind of substrate.
