Definitions
- the present invention relates to a semiconductor device, a stacked semiconductor device, a post-sealing stacked semiconductor device, and a manufacturing method thereof.
- a photosensitive insulating material or a stacked semiconductor device that can cope with an increase in substrate area in productivity improvement and can be used in a high-density mounting technology such as a chip size package, a chip scale package (CSP), or three-dimensional stacking. Therefore, development of the manufacturing method is desired.
- Patent Documents 1 and 2 show an example in which a semiconductor element is placed on a wiring board without using wire bonding, and a method of placing the semiconductor element on a board on which wiring is performed by three-dimensionally stacking the semiconductor elements.
- Patent Document 1 shows an example of a method for manufacturing a semiconductor device having a semiconductor element such as a light receiving element or a light emitting element.
- the semiconductor device 50 includes an Al through a through electrode 56.
- the electrode pad 55 and the rewiring pattern 52 are connected, and the rewiring pattern 52 of the semiconductor device and the rewiring pattern 57 on the wiring board 53 are connected via the solder bumps 58.
- a device formation layer 59 and a plurality of Al electrode pads 55 are formed on the upper surface of the semiconductor device.
- a through hole 54 penetrating the semiconductor device is provided between the Al electrode pad 55 and the rewiring pattern 52 by dry etching, and a through electrode 56 is formed in the through hole 54 by Cu plating.
- the device formation layer 59 is disposed on the upper surface of the semiconductor device and receives light or emits light. According to this method, the semiconductor element 51 and the wiring substrate 53 are not bonded by wire bonding, but rewiring must be performed on the semiconductor device and solder bumps must be disposed. In reality, it is difficult to achieve finer wiring and higher density solder bumps.
- Patent Document 2 discloses a manufacturing method of a semiconductor device useful for three-dimensional stacking of a plurality of semiconductor elements.
- a structure in which a semiconductor element 180 and a semiconductor element 280 are stacked is shown. Illustrated.
- Each semiconductor element to be laminated includes solder bumps (170, 270) on a substrate (110, 210) having a core substrate (150, 250), through electrodes (140, 240), and wiring layers (157, 257).
- the semiconductor element (180, 280) is bonded via the pad (182, 282) of the semiconductor element.
- the wiring layers (157, 257) include mounting pads (165, 265), connection pads (164, 264), and wiring (266).
- Patent Document 2 discloses a method of bonding and laminating substrates on which such semiconductor elements are bonded via solder bumps (174, 176).
- Patent Document 2 since the semiconductor element is bonded to the wiring board by solder bumps, as in Patent Document 1, it is extremely important to increase the density of the solder bumps accompanying the downsizing of the semiconductor elements. You will face difficulties.
- the formation of the through electrode provided on the second substrate 210 has a problem that the process is complicated and not easy.
- Patent Document 3 shows an example of a semiconductor device mounted on a wiring board, a manufacturing method thereof, or a semiconductor device in which semiconductor elements are assembled in a laminated structure, and a manufacturing method thereof.
- Patent Document 3 as shown in FIG. 27, an organic substrate 301, a through via 304 that penetrates the organic substrate 301 in the thickness direction, and an external portion that is provided on both surfaces of the organic substrate 301 and is electrically connected to the through via 304.
- Patent Document 3 as shown in FIG. 28, a photosensitive resin layer 316 applied to the surface layer of a semiconductor element is patterned to form an opening 317, whereby a via portion 308 formed on the semiconductor element 302 is formed.

なお、もちろん、他の感光性樹脂を用いることもできる。
支持フィルムの材質としては、ポリエチレン、ポリプロピレン、ポリカーボネート、ポリエチレンテレフタレート等の合成樹脂フィルム等が挙げられ、適度の可撓性、機械的強度及び耐熱性を有するポリエチレンテレフタレートが好ましい。また、これらのフィルムについては、コロナ処理や剥離剤が塗布されたような各種処理が行われたものでもよい。これらは市販品を使用することができ、例えばセラピールWZ(RX)、セラピールBX8(R)(以上、東レフィルム加工(株)製)、E7302、E7304(以上、東洋紡績(株)製)、ピューレックスG31、ピューレックスG71T1(以上、帝人デュポンフィルム(株)製)、PET38×1-A3、PET38×1-V8、PET38×1-X08(以上、ニッパ(株)製)等が挙げられる。
なお、上面金属配線4aは、所望の配線幅になるように適宜調整すればよいが、特に0.1~10μmの厚さとなるように、第二絶縁層上に形成することが好ましい。
また、貫通金属配線4cのメッキを充足させるため、別途、貫通金属配線4cへ再度電解メッキを施してもよい。
また、第三絶縁層の膜厚が5~100μmであれば、製造する半導体装置を薄型化できるため好ましい。
ソルダーバンプの形成方法としては、例えば、図14に示すように貫通電極上部の開口Eにメッキによって貫通電極上金属パッド19を形成する。次に、貫通電極上金属パッド19上にソルダーボール20を形成し、これをソルダーバンプとすることができる。
また、本発明の半導体装置の製造方法であれば、半導体素子上に微細な電極形成を施し、半導体素子外部に貫通電極を施すことで、配線基板への載置や半導体装置の積層を容易にでき、また貫通電極、電極パッド部の開口などの加工を容易にできる。
さらに、このようにして得られた本発明の半導体装置は、配線基板への載置や半導体装置の積層が容易であるため、半導体装置を積層させた積層型半導体装置やこれを配線基板に載置し封止した封止後積層型半導体装置とすることができる。
