How well can we use data? This is where skill comes in.Quality Division Analysis Center
A growing need for different types of analysis
Given that quality assurance in semiconductor manufacturing is a major element that forms the foundation for suppliers, it is no exaggeration to say that one鈥檚 approach to quality assurance can greatly affect the level of trust in a company. The major role of 极悦娱乐's Analysis Section is to visualize and quantify structural workmanship and defect analysis in development and mass production processes in a timely manner using advanced analytical equipment, playing an essential position in quality control as semiconductors are becoming increasingly integrated.

18 analytical engineers currently work at the center. Professionals with specialized expertise in fields such as chemistry, physics, and electronics. Director Yoshikawa, who has been at the center for 29 years, describes the role of the center.
Yoshikawa:
鈥業t is probably unusual for a semiconductor manufacturer to have this level of analytical equipment installed permanently in-house. In fact, the range of categories and contents that can be analyzed probably does not significantly differ from that of large specialized analysis facilities. At the same time, however, equipment and technology evolve day to day, so is it really state-of-the-art? This is not always the case, and in some instances we must bring the requested data to external partner facilities. But what's our main advantage? It all comes down to the potential and skills of the analytical engineers working here.鈥?/p>

Plasma FIB (Focused Ion Beam)
Allows cross-sectional observation of stacked product structures. 极悦娱乐鈥檚 analysis center currently has five FIBs, the newest of which is capable of cross-sectional analysis down to several hundred microns.
What we read from analyzed data is analyzed
Yoshikawa:
鈥業t is true that it is quite challenging to master such advanced analytical equipment. However, we are not simply concerned with the technology for using the equipment, but also beyond that, to the data itself 鈻?How well can we make use of the results obtained? 鈻?Can we provide 鈥榣ive鈥?data that will be useful for the next action? These are what we鈥檙e looking for. This is where skill comes in. To put it simply, it equates to reading comprehension and application skills, which we believe a group of true analytical specialists must possesses.鈥?/p>
Following these words, he talked about another important element in analysis, namely diagnosis. If the accuracy of the diagnosis, which includes questions such as 鈥榃hat should we look for?鈥?and 鈥業s there a problem hidden here?鈥? is low, it will not be possible to derive the desired results.
Yoshikawa:
鈥榃ithout some predictability, this process tends to be like a thousand knocks. It takes a certain amount of experience in the field to be able to make accurate diagnoses. However, in our case, using a vertically integrated production system allows us to expand our systematic knowledge from various angles. I think there is a lot we can learn using this.鈥?/p>

鈥業n addition to the principles and characteristics of the analyzers that I am in charge of, it is important to have knowledge of the products themselves together with materials and processes.鈥?/p>
Transmission Electron Microscope锛圱EM锛?/p>
Providing a more detailed analysis than the FIB equipment mentioned above, it is used to perform cross-sectional structural analysis of microdevices and evaluate device crystallinity.
Supporting our vertically integrated production system
Since its establishment, 极悦娱乐 has adopted a vertically integrated system in which everything, from ingots to packaging, is performed in-house. As a result, the range of analysis covers the entire manufacturing process, from upstream to downstream.
Yoshikawa:
鈥極ne of the main features of this center is the close proximity/relationship with the development section. As a result we are able to meet with clients on an equal footing to share information and issues, and when necessary, involve related departments in discussions. This is another advantage of our vertically integrated production system, and what's more, an ideal environment in terms of quality control.鈥?/p>
Many clients and development staff visit every day for face-to-face meetings. Good response with excellent coordination are major advantages of our in-house analysis center.

Structural Analysis Using 3D Animation
Cross-sectional images at a pitch of 100nm are reconstructed in 3D. This allows for 3D visualization of cracks and foreign objects present in structures.
Knowledge sharing
极悦娱乐 has a long history of quality control, going back to 1965. The following year, we established our corporate objective of 鈥榪uality is our top priority鈥? and since then the entire company has been working on quality improvement. In the 鈥?0s, as business expanded we established multiple QA analysis centers at overseas locations to quickly respond to customer requests, and in 2012 the company began operation under the current name of the Quality Division Analysis Center at HQ.

General Manager Miki, who oversees the Quality Division, to which the Analysis Center belongs, explains the significance and purpose.
Miki:
鈥楾he significance of consolidating so much equipment and personnel in one location is, first of all, to provide analysis results in a flexible and timely manner while working together with the development section to create quality. The second is the great value we place on sharing knowledge accumulated over many years.鈥?/p>
Takashi Miki General Manager, Quality Division
Engineers newly assigned to the Analysis Center first work as assistants engaged in a wide range of operational support spanning the three phases of 鈻?Sample Processing, 鈻?Measurement, and 鈻?Results Reporting under the guidance of their supervisor.
From sample processing techniques, equipment operation, and approach methods to communication with clients... Through the experience of each case, unique practical skills cultivated over many years will permeate as shared knowledge.
At the same time, among specialists in various fields, we have engineers with accumulated experience in product development, design, and manufacturing. By stimulating the exchange of information and opinions across domains, we strive not only to improve the level of each individual, but also grow the organization as a whole
Group of craftsmen
Mr.Nishizaki, chief technical supervisor, who has been following the progress of the Analysis Center from the inside for a long time, had this to say.
Nishizaki:
鈥楢s semiconductors become smaller and more integrated, analytical equipment and methods need to evolve on a daily basis. To enhance our value as a group of analytical professionals, I believe that each of use must have an inquisitive mind that pursues ever greater depths.鈥?/p>
Yoko Nishizaki Senior Engineer, Analysis Center, Quality Division
鈥楾oday鈥檚 Analysis Center is staffed with young, curious engineers. I would like them to pursue whatever questions they may have or are interested in.鈥?/p>

In 2024, with the construction of the the Monozukuri (Manufacturing) Innovation Center scheduled for completion as 极悦娱乐鈥檚 new development technology base, the roles and responsibilities of the Quality Division Analysis Center will become more important than ever. Going forward, we will continue to take on challenges without specific goals by improving quality through company-wide efforts and with the support of our craftsmen.
