Abstract
【課題】 狭いベース・ドーピング・プロファイルを有する高性能NPNヘテロ接合バイポーラトランジスタを作成する構造および方法であって、その方法によって優れた高周波性能を有するデバイスが製作できることに対する要求がある。
【解決手段】 NPNヘテロ接合バイポーラトランジスタ(100)を作成する構造および方法は、トランジスタのベース領域を形成するためにドーパント(86)を包含する第1領域(82)を有する半導体基板(11)を含む。第1領域に隣接する第2領域(84)は、トランジスタのエミッタ領域を形成するために用いられる。侵入物トラップ材料(81)は、後続の熱処理工程の間に、ベース領域内へドーパントが拡散することを減じる。
【選択図】 図5
Description
atoms)がボロンをドープした層または領域86に達することを効果的に制限し、それによって、侵入物トラップ材料81が無くても狭いベース幅180を維持することができる。バイポーラトランジスタのベースは、デバイスの電流スイッチング能力を制御する領域である。ベースを通って注入された小数キャリアの走行時間は、ベース幅の2乗にほぼ比例するので、ベース幅の縮小によって、劇的にベース走行時間が減少するが、それは、単一電流利得fτの周波数とは逆比例の関係にある。従って、より狭いベースを有するバイポーラトランジスタは、より高い周波数で電流をスイッチングすることができる。
