Abstract

초미세한 바이어스를 알루미늄으로써 충전시키는 다단계 방법은 약 150℃ 온도에서 스피터 증착되는 약 1000옹그스트롱인 알루미늄의 초기 증착을 포함함. 연속해서, 알루미늄 게르마늄 합금층이 다시 150℃ 이하에서 약 1000 옹그스트롱으로 증착된다. 게르마늄 없는 알루미늄의 제3층은 약 150℃ 온도에서 증착된다. 대략 1000 옹그스트롱이 증착된다. 그것은 전체적으로 5000 내지 15000 옹그스트롱인 알루미늄을 증착시키기 위해 450℃ 내지 500℃에서 행해지는 최종 알루미늄 증착에 의해 뒤다라진다. 상대적으로 저온인 150℃에서 2개의 알루미늄 증착은 게르마늄으로 하여금 침전되는 것을 방지하고 게르마늄으로 하여금 중착된 금속의 모든 용해 온도를 증가시키는 상기 층으로 확산되게 하여 연속적인 고치리 온도에서 금속이 바이어스 표면을 디웨트(dewet) 하지 않는다.
