The ROHM Group is an integrated device manufacturer (IDM) that handles all stages of production, from development through manufacturing. ROHM Device Manufacturing Co., Ltd. is responsible for the front-end processes, ensuring the stable supply of high-quality products.
The wafer processing technologies in front-end processes are essential to the mass production of semiconductor devices, including LSIs and discrete products.
In wafer processing, the performance and quality of semiconductor devices are achieved through numerous micrometer- and nanometer-scale microfabrication and chemical treatment processes.
These processes are very complex, and even slight variations cannot be tolerated.
The ROHM Group has cultivated advanced device and processing technologies over many years. This gives us an advantage in SiC power devices and analog LSIs as well as discrete products, including transistors and diodes.
SiC power devices must stably operate in high temperature and high voltage environments; analog LSIs are necessary to improve the energy and operational efficiency of finished products; and high reliability is required for discrete products. For these devices and products, processing precision and reproducibility in front-end processes are important factors that determine product performance.
We realize high reproducibility and stable quality in mass production by optimizing our production facilities and processing technologies for each product’s applications and characteristics.
Based on our accumulated expertise in such technologies and facilities, we support the performance and reliability of semiconductor devices on the manufacturing side
as a global manufacturing leader, mainly in the automotive, industrial, and energy sectors.
