Abstract
Description
電子技術の発展に伴い、電子機器のアップグレードがますます速くなり、電子機器内部に使用されるチップに対する市場の要求もますます高まっている。現在、チップのパッケージについては、必要なチップをパッケージ基板上に直接取り付け、マルチチップのモジュール化を実現しているのが一般的である。しかしながら、パッケージ基板上にチップをパッケージすることが、チップ間の相互接続を実現することが難しい。
パッケージ基板上に半導体基板を配置し、半導体基板上に第1グループのピンと第2グループのピンとを配置し、第1グループのピンと第2グループのピンとを、接続層の複数の接続チャンネルを介して接続することにより、半導体基板上に配置された第1のチップが有する第3グループのピンが第1グループのピンに接続され、半導体基板上に配置された第2のチップが有する第4グループのピンが第2グループのピンに接続され、第1グループのピンと第2グループのピンとが接続されているため、第1のチップの第3グループのピンと第2のチップの第4グループのピンとが接続され、これにより、第1のチップと第2のチップとの相互接続が実現され、従来のパッケージ技術においてパッケージ基板上にチップをパッケージする際に、チップ間の相互接続を実現することが難しいという技術的課題が解決される。
チップパッケージ技術において、2Dパッケージプロセスは、異なる機能を有するアクティブ電子コンポーネント、パッシブコンポーネント、及び微小電気機械システム(Micro Electromechanical System,MEMS)、光学コンポーネントなどの他のコンポーネントを組み合わせて、一定の機能を有する単一の標準パッケージを実現し、一つのシステム又はサブシステムを形成する。2Dパッケージプロセスには、パッケージ精度要求が低く、パッケージ技術的課題が少ないという特徴があり、2Dパッケージプロセスによって得られたパッケージのサイズは比較的大きい。
図1に示すように、当該チップパッケージ構造10は、パッケージ基板110と、パッケージ基板110上に配置された半導体基板120と、半導体基板120上に配置された第1のチップ130及び第2のチップ140とを備える。
