This non-provisional application claims priority under 35 U.S.C. §119(a) on Patent Application No. 2004-16296 filed in Japan on Jan. 23, 2004, the entire contents of which are hereby incorporated by reference.
In the above-described manner, the through hole 3 and protruding part 3 a are integrally and simultaneously formed. Note that it may also be possible to integrally form the metal parts 33, 33, . . . and the protruding parts 3 a, 3 a, . . . by forming a print mask on the front surface protection film 9 except for the openings of the holes 1 a, 1 a, . . . and the periphery of the openings, instead of electroplating, after forming the insulation film in the holes 1 a, 1 a, . . . ; printing a conductive metallic paste on the portion where the print mask is not formed, namely, in the holes 1 a, 1 a, . . . and the periphery of the openings; and hardening the printed metallic paste. In this case, the protruding parts 3 a, 3 a, . . . can have a uniform thickness by adjusting the thickness of the print mask. Further, it may also be possible to form a through hole in the semiconductor substrate 1 by etching, laser irradiation or other method; form the through electrode 3 in the formed through hole by a CVD method, electroplating or other method; and then form the protruding part 3 a.
After forming the semiconductor substrate 1 and through electrodes 3, 3, . . . , the rear surface wiring 4 and rear surface protection film 6 are formed on the rear surface of the semiconductor substrate 1 (FIG. 8B). In this case, the rear surface insulation film 5 is formed first, and then the rear surface wiring 4 connected to the through electrodes 3, 3, . . . is formed. Next, the rear surface protection film 6 is stacked on the rear surface insulation film 5 and rear surface wiring 4, except for portions (land portions) where the solder balls 7, 7, . . . are formed in FIG. 9B.
The semiconductor substrate 1 has through electrodes 3, 3, . . . and protruding parts 3 a, 3 a, . . . which correspond one-to-one with each other. However, the number of the through electrodes 3, 3, . . . is smaller than the number of the through electrodes 3, 3, . . . in the semiconductor device 14 of Embodiment 1, or the layout of the through electrodes 3, 3, . . . is offset compared to the layout of the through electrodes 3, 3, . . . in the semiconductor device 14 of Embodiment 1, and consequently it is impossible to stably support the glass lid 11 only by the protruding parts 3 a, 3 a, . . . .
Therefore, the semiconductor substrate 1 has the protruding parts 30, 30, . . . protruding toward the glass lid 11 on the surface of the image pickup element 12. The protruding parts 30, 30, . . . have a thickness substantially equal to that of the protruding parts 3 a, 3 a, . . . , and the shape, thickness, number and layout of the protruding parts 30, 30, . . . are set so as to stably support the glass lid 11 by the protruding parts 3 a, 3 a, . . . and the protruding parts 30, 30, . . . .
The protruding parts 30, 30, . . . are formed by using the same material as the through electrodes 3, 3, . . . and protruding parts 3 a, 3 a, . . . simultaneously with the formation of the through electrodes 3, 3, . . . and protruding parts 3 a, 3 a, . . . by electroplating or printing and hardening a metallic paste, or following the formation of the through electrodes 3, 3, . . . and the protruding parts 3 a, 3 a, . . . .
On the surface of the image pickup element 12 where the protruding parts 30, 30, . . . are positioned, micro-lenses of the micro-lens part 13 are not formed. Moreover, since the glass lid 11 and the semiconductor substrate 1 are securely bonded together and sealed by the adhesive seal part 10, it is possible to bond or not to bond the top surfaces of the protruding parts 30, 30, . . . and the glass lid 11. The adhesive seal part 10 is not formed in the periphery of the protruding parts 30, 30, . . . so as not to interfere with reception of light by the image pickup element 12.
