摘要:
A method of mounting a semiconductor chip in which an IC chip is mounted by filling a gap between the chip and a substrate with adhesive which functions as an underfill. The fillet of the underfill is made to have a preferable shape. To accomplish this, a head IC chip provided with bumps is placed on a suspension that is covered with the underfill adhesive and is provided with pads. A bonding tool presses the head IC chip and applies ultrasonic oscillation to the head IC chip, so that the bumps are properly bonded to the pads. When the head IC chip is pressed and subjected to ultrasonic oscillation, the ultraviolet rays 108 are emitted so as to harden the peripheral portion 151a of the adhesive 151 spread out between the head IC chip 11 and the suspension 12.

A head assembly is provided with a mounting surface, and an integrated circuit chip which is mounted on the mounting surface and processes signals. The integrated circuit chip is covered by a layer which prevents generation of foreign particles from the integrated circuit chip by the provision of the layer.

A resin coating method for applying resin to a predetermined region of a wiring board includes the steps of imaging an external appearance of the resin extruded from a resin application device; and automatically adjusting an amount of the resin extruded from the resin application device based on the external appearance of the resin obtained in the imaging step.

A wafer receiving conductive input/output bumps on the upward front side is placed on a platen. An underfill material sheet, adhered to the surface of the thin film tape, is superposed on the front side of the wafer. The underfill material sheet is forced to soften. When the underfill material sheet is urged against the wafer, the input/output bumps is allowed to penetrate through the underfill material sheet. After the underfill material is hardened, the thin film tape is peeled off from the hardened underfill material sheet. The underfill material can thus be supplied commonly to a large number of individual semiconductor chips included in the wafer. As compared with the case where the underfill material is supplied separately to the individual semiconductor chips, the working time can greatly be shortened.
摘要:
A method of mounting a semiconductor device having bumps on a board having pads so that each of the bumps is joined to a corresponding one of the pads is provided. Adhesive to be hardened by heat is provided between the semiconductor device and the board. The method includes the steps of pressing the bumps of the semiconductor device on the pads of the board, and heating a portion in which each of the bumps and a corresponding one of the pads are in contact with each other. A pressure of the bumps to the pads reaches a predetermined value before a temperature of the adhesive to which heat is supplied in the above step reaches a temperature at which the adhesive is hardened.
