摘要： A semiconductor device includes a semiconductor substrate having bump electrodes and a sealing film formed thereon, the sealing film having laminated layers. The sealing film interposed between adjacent bump electrodes is prepared by laminating a protective film and each layer of the sealing film on the lower surface of the base film, on the bump electrodes, followed by allowing the bump electrodes to project through the sealing film under pressure and heat. The thickness of the sealing film is smaller than the height of the bump electrode, and thus the bump electrode projects through the sealing film. Particles for lowering the thermal expansion coefficient are dispersed in the sealing film to allow the sealing layers to exhibit a thermal expansion coefficient differing in its thickness direction such that the thermal expansion coefficient in the layer which is close to the semiconductor substrate is close to that of the semiconductor substrate.

摘要： A resin sealing film is formed on a silicon substrate by using a printing mask and a squeegee. The side surface in the tip portion of the squeegee is substantially V-shaped, and the printing is performed by pushing the tip portion of the squeegee into the gap between adjacent bump electrodes. As a result, the sealing film is formed in a manner to be depressed in the region between adjacent bump electrodes so as to facilitate the swinging movement of the bump electrodes. It follows that, in a temperature cycle test performed after the silicon substrate is mounted to a circuit substrate, the stress derived from the difference in thermal expansion coefficient between the silicon substrate and the circuit substrate is absorbed by the bump electrode.

摘要： The back surface of a semiconductor wafer having a plurality of chip-forming regions each provided with a plurality of connection pads on the surface is bonded to a dicing tape, followed by fully cutting the semiconductor wafer along a cut line so as to form a cutting groove. Then, a front side protective film is formed on the front surface. The front side protective film has an open portion exposing the central portion of the connection pad, and is filled in the cutting groove. After formation of a columnar electrode connected to the connection pad via a wiring, a sealing film is formed on the front side protective film. Further, the cutting groove filled with the front side protective film is cut in substantially the center in the width direction, followed by peeling off the dicing tape so as to form individual semiconductor devices each forming a chip.

摘要： A low dielectric constant film/wiring line stack structure made up of a stack of low dielectric constant films and wiring lines is provided in a region on the upper surface of the semiconductor substrate except for the peripheral part of this surface. The peripheral side surface of the low dielectric constant film/wiring line stack structure is covered with a sealing film. This provides a structure in which the low dielectric constant films do not easily come off. In this case, a lower protective film is provided on the lower surface of a silicon substrate to protect this lower surface against cracks.

摘要： First, a trench formed in parts of a semiconductor wafer, a sealing film and others corresponding to a dicing street and both sides thereof. In this state, the semiconductor wafer is separated into silicon substrates by the formation of the trench. Then, a resin protective film is formed on the bottom surface of each silicon substrate including the inner part of the trench. In this case, the semiconductor wafer is separated into the silicon substrates. However, a support plate is affixed to the upper surfaces of the columnar electrode and the sealing film via an adhesive layer. Therefore, when the resin protective film is formed, it is possible to prevent the entirety including the separated silicon substrates from being easily warped.
