The Relationship between the Semiconductor Manufacturing Process and DISCO Products

The majority of DISCO products, which incorporate a broad number of engineering disciplines, such as mechanical, electrical, physical, chemical and IT, are currently used for manufacturing high-value-added semiconductors.

Four Business Fields, Our Unique Total Solutions

DISCO's greatest strength lies in our four distinct business fields, each interwoven to provide total solutions.

Precision Processing Consumable Products

Cutting-edge technology honed for over 70 years.

Our consumable products can be characterized by our abrasive blades and wheels made with synthetic diamonds. When installed on the equipment and rotated at high speed, they cut, grind and polish materials. We manufacture various consumable products including dicing blades and grinding/polishing wheels. Users can make different selections in terms of shape, thickness, bonding material, and diamond size, according to their processing needs.
DISCO was originally established as a manufacturer of abrasive cutting wheels. Ever since our first year in 1937, we have continued to develop these to find solutions for the needs of our customers. In fact, DISCO now can boast tens of thousands of blades and grinding/polishing wheels in our inventory.

Precision Processing Equipment

Limitless innovation and application of advanced Kiru, Kezuru and Migaku technologies

Precision processing equipment is the general term we use to describe the machines that perform our Kiru, Kezuru and Migaku technologies. DISCO has primarily been involved in the development of equipment such as dicing saws and grinders mounted with blades and wheels. However, the processing methods have expanded significantly in recent years beyond our original abrasive equipment, to include laser saws, waterjet saws and plasma etchers. Most DISCO equipment is customized to meet our customers' wide ranging requirements regarding not only device quality and equipment productivity, but also effective use of space and low environmental impact.
DISCO will continue to evolve our core technologies of Kiru, Kezuru and Migaku to help create comfort for people.

Application Know-how

Solutions that truly meet our customers needs

「Precision equipment, consumable products and processing parameters can be combined in a myriad of ways. This can make it difficult for our customers to make equipment selections that are best for them. The facilities in our application laboratory can solve this problem as our application engineers perform test cuts with the materials provided by the customer in order to recommend solutions that will produce the best processing results.
Providing the best processing results in the form of our processing solutions, is the core element offered by DISCO. In an effort to provide free application testing close to our customers, we have application laboratories in our domestic and overseas offices, in addition to the Application Laboratory at our Head Office/R&D center in Tokyo with its 70-plus private test booths.

Service Support

Our enthusiasm for craftsmanship is embodied in our service

DISCO consider the services we provide after product delivery to be an essential aspect of our business. Our service support is primarily comprised of after-sales service, which may involve regular equipment spot checks or repairs, as well as training services to provide our users with opportunities to acquire the necessary operation/maintenance skills. We have created a six-level in-company certification program for our Customer Engineers who are in charge of after-sales service allowing us to provide uniform global service support. When it comes to our training service, we put into practice feedback obtained via questionnaires filled out by the participants in an effort to provide service and support that delight our customers.
The very thing that defines the DISCO spirit is our belief that the care we put into the craftsmanship of our equipment and consumable products must also be fully reflected in our application know-how and service support.

R&D: Creating Future Value

We continue to push the boundaries into uncharted areas of our Kiru, Kezuru and Migaku technologies by actively utilizing original and creative ideas.

Major R&D Center in Tokyo

DISCO's Head Office/R&D Center is located in the Omori region of Tokyo, which has easy access to Haneda Airport as well as Shinagawa Station, where the Shinkansen stops. The site was chosen for our R&D center to be more convenient for our customers to visit us for technological discussions. The content of these early engagements provides a major source of ideas for DISCO's next generation of R&D, and represents a valuable asset to our company.

An R&D Environment that Places Importance on Inspiration and a Challenge

Building B in the Head Office/R&D Center is primarily our R&D facility. This places our engineers' desks adjacent to the area where the R&D equipment is located. The creation of an environment that allows for an immediate examination of the engineers' inspiration using close-by equipment enables DISCO to continue to provide invaluable creative solutions and products even in the rapidly changing semiconductor industry.

Turning Customer Needs into Innovation

What our customers want is not the product itself, but the processing solutions, and we at DISCO place great importance on this approach. Testing helps determine whether the solutions required by our customers can be realized. This testing takes place in the application laboratories of not only our Head Office/R&D Center, but also in our branch, affiliate and agent offices worldwide, which create stronger relationships of trust with our customers. The cycle that contributes to the processing results provides DISCO with a high level of expertise and know-how, and the accumulation of this knowledge helps us to respond to even more complex requirements.

Continually Evolving Monozukuri

The spirit of monozukuri that has been with us from the very beginning is evident throughout our manufacturing process.

DISCO's Origin is in Monozukuri *

DISCO was established as a grinding wheel manufacturer originally named Dai-Ichi Seitosho in the city of Kure, Hiroshima Prefecture in 1937. Although our products have evolved, our stance regarding monozukuri to respond to customers' needs and continue to provide them with true and lasting satisfaction has continued unchanged since the first day. DISCO works out of four different production sites including three in its city of inception, Kure, and one in Chino City in Nagano Prefecture.

* Craftsmanship, pride in manufacturing

Producing Custom-built Products

Although DISCO's equipment comes with standard specifications, most customers require customization for their specific processing needs. Several of DISCO's departments and divisions, such as sales, engineering, purchasing, manufacturing and applications, collaborate to ensure that the specifications requested by the customers are precisely reflected in our products. Particularly when it comes to the important components that directly affect the processing results, we at DISCO make continuing efforts to increase the in-house manufacturing ratio to allow us to provide our customers with a more reliable product.

Creating Customer Delight via Our Evolving Activities

Even at the manufacturing site, we actively utilize PIM* activities that are being developed and expanded throughout the company. Our zero defect activities in blade manufacturing and reduction of assembly man-hours in equipment manufacturing have directly contributed to customer satisfaction in terms of faster delivery of products and a stable supply.

* PIM: Performance Innovation Management
This specifically refers to a program where each department or division sets targets based on the desired future state. The group subsequently looks back over short periods of time to detect any gaps between the targets and the current state in an effort to obtain Kizuki ("lightbulb" moment) for the end purpose of evolving. Visibility of the targets and current state via the abundant use of notices, posters, and Post-it notes encourages all of us to increase our awareness in our daily activities.
