Abstract: Process control monitor (PCM) is a tool to measure and control in the production of large scale integrated circuit. According to characteristics of the structure and process of low-temperature co-fired ceramic (LTCC), the PCM test patterns were designed of gold conductor film、precision of line width and resistors etc of LTCC substrate, by testing the performances of bonding strength, thickness of film, precision of line width and resistance and so on, mastered the degree under control of the process, adjusted the process state timely. The manufacturing technology level of LTCC substrate was stabilized, then the quality and yield of the product were improved.

Key words: low-temperature co-fired ceramic, process control monitor, statistical process control, thickness of film, line width
