This is disclosed in Japanese Patent Application Laid-Open No. 2008-270257.
- the capillary underfill method In the capillary underfill method, a capillary phenomenon is used to infiltrate the underfill material into the gap between the wiring board and the chip. For this reason, if the gap is narrowed or the pitch of the joint portion between the wiring board and the chip is narrowed, the wettability of the underfill material deteriorates due to residues such as flux, and the penetration of the underfill material is hindered. Therefore, there is a limit to narrowing the pitch when using the capillary underfill method. In addition, the sealing process using the capillary underfill method requires a relatively long time, and a process such as flux cleaning is also required. The mounting method using the capillary underfill method has a tact time of the production process. There is a problem that it is difficult to improve productivity by shortening.
- FIG. 28B shows a basic process in this mounting method.

- a chip is formed by selectively applying an underfill material or positioning it with high precision between a wiring board and a chip and then applying pressure under heating. It is necessary to implement. However, from the viewpoint of improving productivity, it is preferable that chip mounting can be performed without requiring selective application of an underfill material or high-accuracy positioning.

It is a chip-like semiconductor element.
- the electronic device for achieving the above-described object is: An electronic device comprising a semiconductor device comprising a wiring substrate and a chip-like semiconductor element flip-chip mounted on the wiring substrate, On the surface of the chip-like semiconductor element facing the wiring substrate, a plurality of solder bumps and a plurality of protrusions made of an insulating material are provided, The chip-like semiconductor element is subjected to a reflow process after being disposed so as to face the wiring board through the underfill material in a state in which the underfill material having a characteristic that the viscosity decreases as the temperature rises is applied on the wiring board. By being flip-chip mounted on the wiring board, It is an electronic device.
- a method for manufacturing a semiconductor device for achieving the above object is as follows.
- a chip-like semiconductor element in which a plurality of solder bumps and a plurality of protrusions made of an insulating material are provided on the surface facing the wiring board is wired with an underfill material having a characteristic that the viscosity decreases as the temperature rises.

Then, the chip-like semiconductor element is reflowed after being disposed so as to face the wiring substrate through the underfill material in a state where the underfill material having the characteristic that the viscosity decreases as the temperature rises is applied on the wiring substrate.
- Implemented by processing Because it is possible to correct the position by self-alignment without the need for heating and pressurizing processes on individual chips, chip mounting is possible without the need for selective application of underfill material or high-precision positioning. Can do. In addition, since the gap between the protrusions of the chip-like semiconductor element becomes a gas flow path during the reflow process, voids in the underfill material during chip mounting can be reduced.

本開示に係る半導体装置、本開示に係る電子機器に用いられる半導体装置、及び、本開示に係る半導体装置の製造方法により製造される半導体装置(以下、これらを単に、本開示の半導体装置と呼ぶ場合がある)において、チップ状半導体素子は、チップ状半導体素子がフリップチップ実装された状態において先端が配線基板に達しないように形成されている突起物を有する構成とすることができる。
チップ状半導体素子の面における突起物が配置される領域には、一定の密度で突起物が設けられている構成とすることができる。
第1の実施形態は、本開示の第1の態様に係る、半導体装置、チップ状半導体素子、及び、半導体装置の製造方法に関する。
配線基板20と対向する側の面に複数のハンダバンプ11と絶縁性材料から成る複数の突起物12とが設けられているチップ状半導体素子10を、温度上昇に伴い粘度が低下する特性を有するアンダーフィル材22が配線基板20上に塗布された状態でアンダーフィル材22を介して配線基板20と対向するように配置した後、リフロー処理を施すことによって配線基板20上にフリップチップ実装する工程を含む。
チップ状半導体素子10を準備し、その上に、電極となるハンダバンプ11を形成する(図6A参照)。次いで、例えばフォトリソグラフィー技術を用いて、ハンダバンプ11で囲まれた領域の内側に、絶縁性材料から成る複数の突起物12を形成する(図6B参照)。
配線基板20を準備し、対向部20A上に、電極となるハンダバンプ21を形成する(図6C参照)。次いで、対向部20A上を含む全面に、アンダーフィル材22を一括して塗布する(図6D参照)。
その後、チップ状半導体素子10を、アンダーフィル材22を介して配線基板20と対向するように配置する。
次いで、リフロー処理を行う。
次いで、アンダーフィル材22Aの硬化処理を行う。硬化処理は、アンダーフィル材の種類に応じて、適宜好適な方法を選択すればよい。硬化後のアンダーフィル材を符号22Bで表す。これによって、配線基板20にチップ状半導体素子10が実装されて成る半導体装置1を得ることができる。
第2の実施形態は、本開示の第1の態様に係るチップ状半導体素子に関する。
第3の実施形態も、本開示の第1の態様に係るチップ状半導体素子に関する。第2の実施形態では、突起物が配置される領域には、一定の密度で突起物が設けられいた。これに対し、第3の実施形態では、領域内の位置に応じた異なる密度で突起物が設けられている。
第4の実施形態は、第3の実施形態の変形例である。第3の実施形態にあっては、各ブロック内には、同一形状の突起物が、一様に同一ピッチで配置されていた。これに対して、第4の実施形態では、形状の異なる複数種の突起物が設けられている点が主に相違する。
第5の実施形態も、本開示の第1の態様に係るチップ状半導体素子に関する。
第6の実施形態は、第5の実施形態の変形例である。第5の実施形態にあっては、ハンダバンプがチップ状半導体素子の面にマトリクス状に配置されていた。これに対し、第6の実施形態にあっては、一部にハンダバンプが配置されておらず、代わりに、突起物が形成されているといった点が相違する。
第7の実施形態は、第6の実施形態の変形例である。
第8の実施形態も、本開示の第1の態様に係るチップ状半導体素子に関する。
第9の実施形態は、本開示の第1の態様に係る半導体装置やチップ状半導体素子に関する。
第10の実施形態は、本開示の第1の態様に係る半導体装置に関する。
第11の実施形態は、本開示の第1の態様に係るチップ状半導体素子に関する。
本開示に係る第12の実施形態は、上述した各実施形態によって得られる半導体装置を搭載した電子機器である。電子機器の概略構成を図26に示す。
以上、本開示の実施形態について具体的に説明したが、本開示は、上述の実施形態に限定されるものではなく、本開示の技術的思想に基づく各種の変形が可能である。例えば、上述の実施形態において挙げた数値、構造、基板、原料、プロセスなどはあくまでも例に過ぎず、必要に応じて、これらと異なる数値、構造、基板、原料、プロセスなどを用いてもよい。
