Abstract
Description
前記両面多層複合感光画素は、1つのシリコンNベース層の上面と底面にいずれもPドーピングを実施し、さらにPドーピング層上にNドーピングを実施することのよって得られるP−N−P、N−P−N−P、P−N−P−N、N−P−N−PーN複合結合によって形成される。
1つのシリコン結晶のNベース層(図4(a))を参照)を取り、正面の画素を必要とするカラーによって分類をし、各類画素に対して、カラー深さの必要に応じて一定の深さのPドーピングを行う。同様に、背面の画素をも必要とするカラーによって分類をし、各類画素に対して、カラー深さの必要に応じて一定の深さのPドーピングを行う。P不純物の埋め込み深さは、感応しようとするスペクトルの波長によって決められる。
1つのシリコン結晶体のN又はPベース層(図9−14を参照)を取り、正面上に単一面2層又は1層の方式で、1つ又は2つの感光画素層を作り、背面上にも単一面2層又は1層の方式で、1つ又は2つの感光画素層を作る。これらの異なる配置によって、1つの両面多層の複合感光画素の複合結合が構成されるが、中には、N−P−Nや、P−N−P、N−P−N−P、P−N−P−N、N−P−N−P−N、およびP−N−P−N−Pなどの各種情況が含まれる。
両方向感光に使われ、『マルチスペクトル感光部材およびその製作方法』(中国出願番号:200810217270.2)に説明された画素方向選択又はセクション方向選択方式を使用する場合は、正面のある画素類又は画素セクションには遮光コーティングが実施されるとともに、背面のその他の画素類又は画素セクションにも遮光コーティングが実施される。
上記実現において、感光ゲート(Photo Gate)で感光ダイオード(Photo Diode)を代替することができ、これによって、感光ゲートに基づく、単一面2層、両面2層、および両面多層感光部材が得られる。
本発明では最適化実現を例として挙げて説明しているが、これらの説明を何らかの制限であると理解してはいけない。画像感光部材(トランジスターチップなど)に詳しく、本文を熟読した者なら、数多くの変化や発揮はいずれも可能で、これらの変化と発揮が本発明の本当な精粋と簡単な変化でさえあれば、依然として本発明の範囲に属すると見なす。
