Definitions
- the present invention relates to a semiconductor device and a method for manufacturing a semiconductor device.
- it relates to a semiconductor device in which a semiconductor chip is flip-chip bonded to a substrate or the like.
- a method of mounting a semiconductor chip on a substrate or the like is to form a bump on an electrode pad of the semiconductor chip without directly bonding a wire such as a gold wire, and directly connect the bump to a land of the substrate.
- a coupling method using a flip chip For example, bumps (protrusions) are respectively formed on the main surfaces of a plurality of electrode pads which also have aluminum (A1) force formed on the main surface of a semiconductor chip.
- the bumps and lands formed on the substrate or the like are directly connected.
- the bumps are formed of gold (Au) using a wire bonding technique, so-called start bumps, or a barrier metal is formed in advance on the main surface of the electrode pad, and the barrier metal is formed using solder.
- Au gold
- a flip chip bonding method is a method of bonding to a semiconductor chip or a substrate in a twisted-down manner by a thermo-compression bonding method or a thermo-compression bonding method using ultrasonic waves.
- an underfill resin is injected between the semiconductor chips or between the semiconductor chip and the substrate (gap). The underfill resin is injected so as to fill the entire gap between the semiconductor chips or the entire gap between the semiconductor chip and the substrate.
- Japanese Patent Application Laid-Open No. 2003-234362 discloses a manufacturing method of forming a dam with a high-viscosity resin around a flip chip and then injecting the underfill in order to prevent the underfill from flowing out. Is disclosed.
- the substrate and the flip chip are bonded by a plurality of solder bumps. It is disclosed that underfill is injected and solidified in a portion between the substrate and the flip chip where no solder bump is surrounded by the dam.
- a substrate and a plurality of solder bumps formed on the substrate, a flip chip bonded to the substrate by these solder bumps, and a semiconductor chip injected between the substrate and the flip chip are disclosed.
- a semiconductor device includes a resin to be solidified, and a solder dam formed on the substrate so as to surround the periphery of the flip chip and blocking outflow of the resin onto the substrate. According to this semiconductor device, it is possible to reduce the area required for forming a dam for preventing resin from flowing out, and it is possible to form a solder dam in the same step as the step of forming a solder bump. It has been disclosed that it will be possible to eliminate factors that increase costs.
- Patent Document 1 Japanese Patent Application Laid-Open No. 2003-234362
- the gap between one semiconductor chip and another semiconductor chip, or the gap between a semiconductor chip and a substrate has become narrower with miniaturization of the device. In other words, the gap is being narrowed. With this narrowing of the gap, the penetration of the underfill resin into the gap deteriorates. In order to improve the penetration of the underfill resin, the viscosity of the underfill resin has been reduced. However, while lowering the viscosity improves the penetration of the underfill resin into the gaps, the underfill resin flows toward the electrode pads and external lands located around the semiconductor chip or substrate. There was a problem that the electrode pads and external lands were contaminated.
- An object of the present invention is to provide a semiconductor device and a method of manufacturing a semiconductor device in which components such as an electrode pad formed on the surface of a substrate or a semiconductor chip are prevented from being contaminated by an underfill resin. I do.
- the first member and the second member fixed to the first member with a gap therebetween so that the surfaces are substantially parallel to each other. And an underfill resin filled in the gap.
- a protective film for protecting the first member is formed outside a region where the second member is projected on the first member, and the protective film is formed from a surface of the first member. It is formed to protrude and become a weir.
- the first member and the second member fixed to the first member with a gap therebetween so that the surfaces are substantially parallel to each other.
- a member and an underfill resin filled in the gap are provided.
- a concave portion is formed outside a region where the second member is projected on the first member.
- the first member and the second member fixed to the first member with a gap therebetween so that the surfaces are substantially parallel to each other.
- a member and an underfill resin filled in the gap are provided.
- a through-hole penetrating the first member is formed outside the region where the second member is projected on the first member so as to surround the region.
- the method for manufacturing a semiconductor device includes the first member and the second member fixed to the first member with a gap so that the surfaces are substantially parallel to each other; Forming a first pad on a surface of a second member outside a region where the first member is to be arranged, in the method of manufacturing a semiconductor device including the underfill resin disposed in the gap. Forming a second pad for connecting the first member on the surface of the second member, and forming a force-raising portion by disposing a conductive member on the surface of the first pad. After the raising portion forming step and the force and raising portion forming step, an underfill resin arranging step of arranging an underfill resin between the first member and the second member is included.
