Similar to analog circuits, which use EM waves at communications frequencies, components in photonics integrated circuits (PICs), which use EM waves at optical frequencies, are sensitive to layout and manufacturing variations—arguably more so. Similar to their semiconductor counterparts, which transmit information… Read More

Understanding Sheath Behavior Key to Plasma Etch
Readers of SemiWiki will be well aware of the challenges the industry has faced in photolithography in moving to new nodes, which drove the development of new EUV light sources as well as new masking techniques. Plasma etching is another key step in chip manufacturing that has also seen new challenges in the development of new sub-10nm… Read More
