Benefits And Limits Of Using ML For Materials Discovery


Machine learning tools can accelerate all stages of materials discovery, from initial screening to process development. Whether the goal is to identify new applications for known materials or to design new molecules for a particular task, these tools help materials scientists find correlations in large data libraries. Still, machine learning tools are not magic. “Software tools are only as... » read more

Mask Complexity, Cost, And Change


Experts at the Table: As leading-edge lithography nodes push further into EUV and beyond, mask-making has become one of the most critical and costly aspects of semiconductor manufacturing. At the same time, non-EUV applications are stretching the lifetime of older tools and processes, challenging the industry to find new solutions for both ends of the spectrum. Semiconductor Engineering sat dow... » read more

Many Options For EUV Photoresists, No Clear Winner


In EUV lithography, and especially high-numerical-aperture EUV, balancing tradeoffs between resolution, sensitivity and line-width roughness is becoming increasingly difficult. Lithography patterning using extreme UV exposure depends on a resist mask that can simultaneously meet targets of small feature resolution, high sensitivity to EUV wavelength, and acceptable linewidth roughness. Unfor... » read more

Innovations Driving The Advanced Packaging Roadmap: Part One


Advanced IC substrates (AICS) have been marching toward the 2µm line/space (L/S) redistribution layer (RDL) technology node for some time (figure 1). However, many questions remain about the ability of organic substrates to meet the line/space requirements of the next generation of advanced packages (AP), those below 2µm L/S and perhaps to 1.5µm L/S. Simply put: are organic substrates up to ... » read more
