NIPPON FILCON CO., LTD. List of Products and Services

Our company offers a "Photo Etching Processing Service" that applies etching to metal sheets and foils, such as cut sheets and roll materials. We can achieve flat processing without distortion or burrs, and we also accommodate "half etching," which creates patterns on only one side, and "taper processing." Additionally, we provide "no-bridge etching," which has no bridges on the outer edges, "backing material etching," which can process thin sheets at the micron level, and we can also handle the processing of molybdenum, which requires advanced technology. 【Features】 ■ Capable of handling everything from prototypes to mass production ■ Prototype processing can be delivered in as little as 2 days ■ Supports large format processing up to 1050×1750mm ■ Smooth processing without burrs or distortion ■ Capable of producing perforated plates and mesh products * We are currently offering free information on our features and product examples! * We are also providing "Basic Knowledge of Etching Processing That You Can't Ask Now!" for free! * For more details, please refer to the PDF materials or feel free to contact us.

In the rapidly changing field of MPU-oriented BGA, IC package peripheral circuits, and COF for LCD driver IC implementation, there is always a demand for product trends. The impact is similar in photomasks, but our drawing machines can meet the required precision for the future. We have responded quickly to the continuously evolving environment. As high definition accelerates, photomasks made by Filcon become increasingly valuable for delicate patterning. 【Features】 ■ Quick delivery response is possible ■ The precision of 9-inch masks is at the world’s highest level ■ Supports large-sized masks ■ Proven track record with major package manufacturers *For more details, please refer to the related link page or feel free to contact us.

Nihon Filcon has a proven track record of delivering numerous reticles for semiconductor photomasks, focusing on discrete, power devices, ASICs, microcontrollers, and centered around the 0.35µm rule. Since the introduction of OMEGA in 2001, we have actively invested in equipment. We also have a robust inspection system that guarantees the quality of our mass production factory, and we are steadily increasing our achievements. We fully understand that cost competitiveness is increasingly required in this industry. As your partner in manufacturing, please feel free to reach out to us. 【Features】 ■ Numerous delivery records to major semiconductor manufacturers ■ Cost competitiveness ■ Equipped with high-performance drawing machines and inspection equipment ■ Skilled technical staff ready to tackle special requests ■ Accepts both EB data and GDSII ■ Capable of producing high-precision 9-inch masks for backside and post-process applications *For more details, please refer to the related link page or feel free to contact us.

The "Mask Data Restoration Service" restores mask data using a process that is the reverse of the usual photomask manufacturing process. Some products have been used for many years without any revisions, depending on the device. For example, power devices for railways typically have a long average product lifespan and require long-term product warranties. However, due to outdated data formats, it may be impossible to read the data, or it may be unusable due to aging deterioration. Our service can restore data in stream format as long as the physical photomask remains, even in such cases. We have already achieved many data restorations, primarily within Japan. If you are facing difficulties, please feel free to consult us. *For more details, please refer to the related link page or feel free to contact us.

The market for optical semiconductors, including communication infrastructure and the LED market, is expected to expand even further in the future. Optical devices vary in required characteristics such as cost and waveguide properties depending on the target products, and we offer a variety that can accommodate all of them. We understand what is important in achieving device characteristics, and our skilled engineers are always ready to tackle your challenges. Please feel free to contact us when needed. 【Features】 - Extensive track record in optical waveguides (AWG, PLC, etc.) - Understanding of what is important in achieving device characteristics - Numerous achievements with major manufacturers in the optical device industry - Skilled engineers ready to take on your challenges at any time *For more details, please refer to the related links page or feel free to contact us.

At Nippon Filcon, we support almost all mask sizes currently in use. Based on vertical and horizontal lines, we can accommodate line and space down to a minimum of 0.5µm. In practice, the resolvable line width varies depending on the mask size, so we will provide a response regarding feasibility after design confirmation. Please feel free to contact us when you need assistance. 【Features】 ■ Supports almost all mask sizes currently in use ■ Custom sizes can be achieved by cutting glass ■ We also handle sizes larger than 10", accommodating up to a maximum of 813mm x 813mm ■ Based on vertical and horizontal lines, we can accommodate line and space down to a minimum of 0.5µm *For more details, please refer to the related link page or feel free to contact us.

A "photomask" is a tool used in the manufacturing of electronic devices (semiconductors), displays, printed circuit boards, micro-machines/MEMS, and serves as the master for patterning. To put it in photographic terms, it acts like "negative film," while the substrate that forms electronic circuits corresponds to "photo paper." Our company provides highly reliable and high-precision photomasks made possible by our long history and cutting-edge technology. Please feel free to contact us when you need assistance. 【Applications (partial)】 ■ Electronic devices (semiconductors/integrated circuits) such as CPUs and memory ■ Discrete semiconductors with single functions, such as transistors and capacitors ■ Light-receiving and emitting elements such as CCD/CMOS image sensors and LEDs ■ Printed circuit boards such as motherboards ■ Image display devices such as LCDs and OLEDs *For more details, please refer to the related link page or feel free to contact us.
