Abstract: 본 발명은 반도체 집적회로에 사용할 수 있는 집적 가능한 수동 인덕터의 제작 방법에 관한 것으로, 평판형 인덕터의 기생 효과를 줄임으로써 우수한 성능의 수동 인덕터를 제작하고 이를 통신용 회로인 전압제어발진기(Voltage Controlled Oscillator), 저잡음 증폭기(Low Noise Amplifier), 전력 증폭기(Power Amplifier) 등의 회로 설계에 응용할 수 있도록 하기 위한 것이다. 
     본 발명은 경제성, 집적도 측면에서 타공정에 비해 유리한 씨모스(CM0S) 공정기술에서 여러개의 금속층을 사용하는 점을 이용하여 기존의 나선형 인덕터와 달리 3차원 구조로 구현하였다. 물론 이 구조는 갈륨비소(GaAs), 바이폴라(Bipolar), 바이씨모스(BiCMOS) 공정기술에서도 그대도 적용된다. 제작 방법은 3개의 금속층을 사용하는 반도체 제조 공정의 경우, 도 4에서와 같이 상층의 금속선(43)과 하층의 금속선(44), 그리고 그 사이에 두 금속선 사이의 간격을 멀게 하기 위해 두 번째 금속층(46)을 삽입하고, 금속선들은 비아홀(45)을 뚫어 연결하면 된다. 이와 같은 구조로 제작했을 경우의 장점은 자기장의 방향이 주로 수평방향(41)으로 형성되기 때문에 수직으로 형성되는 자기장의 영향에 의한 인덕터의 성능 저하를 감소시킬 수 있다는데 있다. 또한 구조가 반복적이기 때문에 모델링이 유리하고 설계가 용이하다는 특징을 갖는다.

Abstract: PURPOSE: A method for fabrication a high temperature superconductor device is provided to allow a use of a high temperature superconductivity single crystal having inherently Josephson junction by reducing a critical current and realizing an electrode attaching technique capable of controlling a contact area. CONSTITUTION: The method begins with attaching the high temperature superconductivity single crystal(30) onto a nonconducting substrate by an adhesive. Then, a surface protective layer(40) is formed by depositing a metal onto the single crystal(30) and patterning to partially expose the single crystal(30). The exposed single crystal(30) is then etched to a predetermined depth, so that a fine projection structure is formed. Thereafter, an insulating layer(50) is formed on the exposed single crystal(30) between the adjacent protective layers(40). Then, a metal is deposited on a resultant entire surface and patterned to form the electrode(60) isolated by the insulating layer(50).
