A package structure and a package process are proposed in using pillar bumps to connect an upper second chip and through silicon vias of a lower first chip, wherein a gap between the first chip and the second chip can be controlled by adjusting a height of the pillar bumps. In other words, the pillar bumps compensate the height difference between the first chip and a molding compound surrounding the first chip so as to ensure the bondibility between the pillar bumps and the corresponding through silicon vias and improve the process yield. Furthermore, the pillar bumps maintain the gap between the second chip and the molding compound for allowing an underfill being properly filled into the space between the first chip and the second chip.

Disclosed is a synthetic leather produced by directly coating a water-soluble synthetic resin solution on the surface of a fabric to form a film thereon such that fine gaps formed on the fabric are partially left open to have a certain degree of air permeability. In particular, a brushing process is used for brushing the surface of a fabric using a brushing machine to raise a nap. Next, a hydrolysis-resistant and flame-retardant resin solution is coated on the back of the fabric, which is opposite to the surface on which the nap is raised, to reinforce the back of the fabric. A film forming process then applies a water-soluble polyurethane resin solution to the nap raised on the surface of the fabric to form a film on the surface of the fabric thereby producing a synthetic leather product that has air permeability properties that are superior to genuine leather.

A seat structure capable of dealing with both a normal posture and a resting posture and providing sufficient relaxation in the resting posture while ensuring excellent comfortableness of an occupant.According to the present invention, a back frame 20 itself is fixed to a frame support 10 but a cushion frame 30 shifts from a first position A to a second position B according to an occupant's movement and an inclination angle of a pelvis support 31 increases accordingly.
