Description
図1A〜Bは、本発明によるオンチップコンデンサ102を有する磁気センサ100の実施形態の例示的実施形態を示す。図示の実施形態で、センサ100は、VCC端子104およびグランド端子106を有する2線ホール効果型センサである。コンデンサ102は、例えば、VCC端子104とグランド端子106の間に結合された減結合コンデンサとして設けることができる。以下でより完全に説明するように、コンデンサ102は、例示的実施形態ではVCC端子104と同じ電位にあるVCCキャップ端子108に結合することがきる。VCCキャップ端子108とVCC端子104は、ワイヤボンディングなど適切な任意の技法を用いて電気的に結合することがきる。この構成により絶縁破壊試験が可能になる。別の実施形態では、VCCとVCCキャップボンドパッドを一緒にして単一のパッドを形成するステップもできる。
第1および第2のオンチップコンデンサがそれぞれの基板の上に示されているが、他の実施形態では、1つまたは複数のオンチップコンデンサがそれぞれの基板の下にあることを理解されたい。一般に、オンチップコンデンサを形成する各導電層は、それぞれの基板と概して平行である。コンデンサの形状は変わり得ることを理解されたい。例えば、図6Cに示された別の実施形態では、1つの導電層、または複数の導電層を加工して、オンチップ集積コンデンサを形成することがきる。一実施例では、単一の導電層をパターニングして、オンチップ集積コンデンサを形成する。別の実施形態では、複数の導電層をパターニングして、1つまたは複数のオンチップの互いにかみ合わせたコンデンサを形成することがきる。コンデンサを形成するために使用される誘電体材料の特性は、コンデンサのインピーダンスを考慮したものであることを理解されたい。
例えば、図8Aおよび図8Bは、オンチップコンデンサを備えた複数のダイを有するフリップチップ構成を示す。集積回路700は、リードフレーム704上に配置された第1のダイすなわち基板702を含む。第1のオンチップコンデンサ706は、第1のダイ702の一部分の上に形成される。第1のダイ内に、任意選択のセンサ素子707を形成することがきる。
上記のように、第1のダイ702と第2のダイ708は、同じ材料として、またはそれぞれ異なる材料として提供することがきる。例示的な材料は、Si、GaAs、InP、InSb、InGaAsP、SiGe、セラミック、およびガラスを含む。さらに、第1および第2のダイ内の感知素子は同じ種類のデバイス、またはそれぞれ異なる種類のデバイスとすることがきる。例示的なセンサ素子は、ホール効果、磁気抵抗、巨大磁気抵抗(GMR)、異方性磁気抵抗(AMR)、およびトンネル磁気抵抗(TMR)を含む。それぞれのオンチップコンデンサ706、714は、上記で論じたように、所望のインピーダンスを実現するようにサイズ変更することがきる。
