図2は、本技術の第1の実施の形態における半導体パッケージ200の断面図の一例である。この半導体パッケージ200は、ガラス210、支持体220、センサーチップ230および基板240を備える。同図において、矢印は、光学部110(不図示)からの入射光の入射方向を示す。
次に図4から図12を用いて半導体パッケージ200の製造方法について説明する。
上述の第1の実施の形態では、基板240の上面にトレンチ244を形成して接着剤251の流れ出しを抑制していたが、この構成では、センサーチップ230の傾きを防止することが困難である。この第2の実施の形態における半導体パッケージ200は、フィラー入りのダイボンド樹脂によりセンサーチップ230と基板240とを接着した点において第1の実施の形態と異なる。
上述の第2の実施の形態では、フィラー271を含むダイボンド樹脂270により、隙間を確保していたが、この構成では、隙間の容積をより大きくすることが困難である。この第3の実施の形態における半導体パッケージ200は、基板240にトレンチ244を形成した点において第2の実施の形態と異なる。
上述の第1の実施の形態では、トレンチ244により規定の領域外への接着剤251の流れ出しを抑制していたが、この構成では、諸条件によっては、受光部231へ接着剤251が流れ出してしまうおそれがある。この第4の実施の形態における半導体パッケージ200は、支持体220に突起部を設けて突起部およびセンサーチップ230の間にシリコーン樹脂を充填した点において第1の実施の形態と異なる。
上述の第1の実施の形態では、基板240にトレンチ244を設けることにより、接着剤251の流れ出しを抑制していたが、接着剤251が想定以上に過多である場合などに、流れ出しを十分に抑制することができないおそれがある。この第5の実施の形態の半導体パッケージ200は、支持体220にスリットを設けた点において第1の実施の形態と異なる。
上述の第5の実施の形態では、支持体220にスリット221や222を形成していたが、接着剤251や252が想定以上に過多であった場合に、流れ出しを十分に抑制することができないおそれがある。この第5の実施の形態の変形例における半導体パッケージ200は、支持体220に貫通孔を形成した点において第5の実施の形態と異なる。
本開示に係る技術(本技術)は、様々な製品へ応用することができる。例えば、本開示に係る技術は、自動車、電気自動車、ハイブリッド電気自動車、自動二輪車、自転車、パーソナルモビリティ、飛行機、ドローン、船舶、ロボット等のいずれかの種類の移動体に搭載される装置として実現されてもよい。
