Abstract
Description
端まで間隔を開けて配置される。しかしながら、説明のため、図3と図4にはただ1つの他の複合ウェル結束部である複合ウェル結束部44しか図示していない。
ウェル間STI26、ウェル内ウェルSTI30、n+活性領域29、およびp+活性領域28をnウェルリング24と絶縁分離pウェル22の上に形成する。複合ウェル結束部34,44を同時に、nウェルリング23と同じマスクで形成する。nウェルプラグ27はnウェルリング24と同時に形成する。nウェルプラグ27は、約1e17原子/cm3〜1e19原子/cm3の範囲の濃度でドープし、埋込nウェル25を約1e17原子/cm3〜5e19原子/cm3の濃度でドープする。次にp+活性領域36、ウェル間STI38、n+活性領域40、およびウェル内STI42を、nウェルプラグ27の上に形成する。p+活性領域36はnウェルプラグの周囲に保護リングを形成し、プロセス感受性の漏れを無くすと共に、複合nウェル結束部をより丈夫にする。
