Exploring the Superiority of Silicon Carbide in Optical Components Silicon carbide (SiC) is a leading material for high-performance optical components, offering numerous advantages over traditional materials such as glass and metal. Its exceptional specific stiffness, high thermal conductivity, and outstanding dimensional stability position SiC as a superior choice compared to beryllium and low-expansion glass ceramics. Historically, the high costs associated with the preliminary shaping and final finishing of SiC have hindered its widespread adoption in optical systems. The material is both hard and strong, requiring precision machining with expensive diamond tooling on high-quality, rigid machine tools. However, advances in manufacturing techniques, such as near-net-shape slip casting, have demonstrated success in reducing costs despite necessitating significant diamond grinding. Building on this success, Entegris offers an entirely new way of creating SiC. Using our chemical vapor conversion process, we can create net- or near net-shaped SiC components in complex forms while spending much less time on fabrication.

Designing for Extended Performance in Life Science Contaminant Removal Filters have a finite lifetime, and their performance also changes over time. How do you get the most performance over the longest lifespan?

Entegris Offers New FOUP Form-Factors for Non-Standard Wafers Over the last few years, 3D stacking has gone from a relatively niche fabrication method to an absolute necessity for cutting-edge applications. As chipmakers delve into smaller and smaller nodes, stacking and die-bonding wafers has become a preferred way of creating more processing power in a smaller space. Stacked and bonded wafers don’t behave the same way as 2D wafers: Wafers are thinned prior to bonding, which results in wafers that can sag when handled Bonded wafers are thicker and heavier than 2D wafers when assembled Bonded wafers can also warp following assembly Many automation tools rely on the predictable geometry and characteristics of 2D silicon wafers for safe handling and transport. While stacked and bonded wafers are a game-changer for miniaturization, they can also force manufacturing compromises unless chipmakers adopt specialized tools for the back end of the line (BEOL).
