Semiconductor thermal processes span a wide temperature range. LPCVD processes require tight process control at mid- to low temperatures. Atmospheric processes require stability over longer durations at elevated temperatures. The demands differ, and the heating element must match them. Light-gauge elements enable faster response in lower-temperature processes, while heavy-gauge elements are used where stability is needed at higher temperatures. Kanthal’s Fibrothal® heating elements are designed to cover this range, supporting both horizontal and vertical furnace configurations used in semiconductor manufacturing. Understanding how heating requirements shift across temperatures helps when selecting the right solution or reviewing process performance.
