Abstract:
An assembling method, a manufacturing method, a device and an electronic apparatus of flip-die are disclosed. The method for assembling a flip-die, comprises: temporarily bonding the flip-die (205) onto a laser-transparent first substrate (204), wherein bumps (202) of the flip-die (205) are located on the side of the flip-die (205) opposite to the first substrate (204); aligning the bumps (202) with pads (206) on a receiving substrate (207); irradiating the original substrate with laser (208) from the first substrate side to lift-off the flip-die (205) from the first substrate (204); and attaching the flip-die (205) on the receiving substrate (207). A faster assembly rate, a smaller chip size, and a lower profile can be achieved.

Abstract:
An electronic package may be fabricated by forming a first layer of insulating material on a first substrate such that the first layer covers a contact pad; forming an opening through the first layer to expose the contact pad; forming an un-patterned second layer on the first layer, the second layer including an adhesive having a viscosity less than that of the first layer, wherein a region of the second layer obstructs the contact pad; removing the region to re-expose the contact pad; aligning a second substrate with the first substrate such that a via of the second substrate is aligned with the opening; bonding the first substrate and the second substrate together at the second layer; and forming an interconnect in contact with the contact pad by depositing a conductive material through the via and the opening.

A method for manufacturing a device package may include constructing a spacer element coupled with a surface of a semiconductor die unit, where the spacer element is configured to create a gap between the semiconductor die unit and a surface of a carrier, and encapsulating the semiconductor die unit within a mold compound, where the encapsulating includes introducing the mold compound into the gap.
Abstract:
The present invention relates to a manufacturing method of a chip package, the method comprising: forming first leads and second leads, both having conductivity, on the top and bottom surfaces of a metal substrate; half-etching the top surface of the metal substrate to form a lead portion under the first leads and to form a die pad portion whose bottom is connected to the lead portion; attaching a chip onto the die pad portion and electrically connecting the chip and the first leads by a connector; forming an insulative molding portion on the metal substrate to bury the chip and the connector; and etching the bottom of the metal substrate to short-circuit the lead portion and the die pad portion, and a chip package manufactured using the same. Accordingly, the distance between a chip and first leads can be reduced by forming a conventional bump-shaped I/O pad in a lead shape, thus lead to cost reduction. Moreover, a large number of signal transmission systems can be reliably realized in a micro-pattern due to the lead shape. Moreover, the stability of the product can be improved by treating the thickness of the lead portion in the final step of the process.
Abstract:
A method of processing a substrate (1) that displays out-gassing when placed in a vacuum comprises placing the substrate in a vacuum and performing an out-gassing treatment by heating the substrate (1) to a temperature T1 and removing gaseous contamination emitted from the substrate (1) until the out-gassing rate is determined by the diffusion of the substrate's con¬ tamination and thus essentially a steady state has been established. Afterwards, the temperature is lowered to a temperature T2 at which the diffusion rate of the substrate's contamination is lower than at T1. The substrate (1) is further processed at said temperature T2 until the substrate (1) has been covered with a film (16) comprising a metal.
