The Challenge
Due to the high-precision nature of the semiconductor industry, it is important that Photronics controls their products and processes to ensure that quality photomasks are shipped to their customers. Photronics management recognized the need for a well thought out enterprise-wide SPC System and conducted a thorough investigation of several SPC packages.
About The Customer
Photronics is a leading worldwide manufacturer of photomasks, high precision quartz plates that contain microscopic images of electronic circuits. A key element in the manufacture of semiconductors, photomasks are used to transfer circuit patterns onto semiconductor wafers during the fabrication of integrated circuits and are produced in accordance with circuit designs provided by customers at strategically located manufacturing facilities in Asia, Europe, and North America.
The Solution
By standardizing their statistical analysis tools, Photronics shares gains in the quality improvement process between manufacturing sites. A cross-functional team at Photronics developed a matrix of selection criteria, conducted a thorough investigation of several SPC packages, and used a weighted voting process to choose STATISTICA Enterprise/QC. They selected STATISTICA based on its ease of integration with the existing manufacturing execution system and the flexibility it provides beyond the system. The STATISTICA Enterprise/QC implementation was coupled with a rigorous SPC training program for the quality and engineering organizations which focused on the comprehensive analytical tools included in the STATISTICA software, which includes hundreds of statistical analyses and graphs. In addition, the Photronics team decided to create a limited number of charts for operators to use initially and provided training for the engineers so that they could conduct their own analysis to determine what “critical-to-quality” characteristics should be monitored.

Modular AI Defect Inspection Solution for Efficient Semiconductor Equipment Upgrades
Smasoft Technology Co., Ltd., a System Integrator that develops industrial automation software and offers AI application solutions, was commissioned by a semiconductor equipment manufacturer to implement AI inspection features into their Extreme Ultraviolet Light (EUV) pod inspection machines. The existing AOI software in the EUV pod inspection machines could only identify defective products but could not trace the cause of the defects. The manufacturer wanted to upgrade their machines with AI features to make the products more useful. The AI solution needed to complete the analysis of 380 images for a single pod within two minutes and inspect different materials simultaneously. This required multiple sets of AI models for interpretation. The solution also needed to be installed in a cabinet in the lower half of the machines, which posed a challenge due to the limited space. Smasoft needed to purchase a hardware solution with strong computing performance, stable operation, compact size, and flexible configuration to overcome these challenges.

Rapid Hybrid Services Deployment for Global Semiconductor Company
The U.S. manufacturer of engineered materials, optoelectronic components, and semiconductors was focused on growth through mergers and acquisitions (M&As). In 2019–2020, it acquired a global electronics firm and needed immediate connectivity and visibility into the acquired firm’s geo-distributed operations. The company had a highly compressed timeline, with only days to integrate the firm’s DDI operations, while deferring a full network migration to a future date. The company was actively engaged in acquiring and merging strategically aligned companies as a key global growth strategy. The company needed to rapidly integrate its new operations, which included significant remote locations in Asia. The company turned to Infoblox to quickly design a highly secure, available, and reliable solution that could deliver full visibility into new sites. It needed dynamic scalability to accommodate its growing operations and the ability to unify a disparate, geo-diverse infrastructure.

Optimizing Semiconductor Manufacturing Yield with IoT
A large U.S.-based manufacturer of high-performance semiconductors was facing a significant challenge in optimizing the manufacturing process of its wireless products. The company, which designs and delivers a broad set of cutting-edge products including radio frequency filters, amplifiers, modulators, attenuators, and more, was experiencing lower than expected overall yield in some of its most complex products. This was affecting the company's productivity and profitability, and there was a need for a solution that could predict low-yield wafers early in the process and identify process improvements to increase overall yield.

Leveraging Xenko Game Engine for Immersive VR Experiences: A StarBreach Case Study
Silicon Studio, the developer of the open-source cross-platform game engine Xenko, was looking to showcase the impressive graphical capabilities of their product. They aimed to demonstrate the engine's compatibility with VR and its ability to deliver high-quality virtual reality experiences and games. To achieve this, they needed to create a demo game, StarBreach, that would effectively highlight these features. However, they required an experienced art production team that could create high-quality game art for StarBreach. The challenge was not only to create visually appealing assets but also to demonstrate the technological possibilities of the Xenko game engine.
