It’s the line in the sand between hitting spec and scrapping the lot. A 2°C drift in soft bake or hard bake will eat your critical dimension control and bake residual stress right into the photoresist stack. We built the infrared lamp to live with that constraint, not fight it.&lt;/h1&gt;&#xA;&lt;p&gt;현장에서는 폴리이미드 베이크가 단순한 열처리 공정 그 이상이다. 이는 규격 충족과 전량 폐기 사이의 경계선과 같다. 소프트 베이크나 하드 베이크에서 2°C의 편차는 치수 기준(control of critical dimension)과 베이크 후 잔류 응력을 포토레지스트 스택 내부에 그대로 침투시킨다. 당사는 이러한 제약 조건을 극복하기보다는 수용할 수 있도록 적외선 램프를 설계했다.&lt;/p&gt;</description>
