Polymer Nanoparticles Applied in the CMP (Chemical Mechanical Polishing) Process of Chip Wafers for Defect Improvement and Polishing Removal Rate Response

open access: yesPolymers, 2023
Chemical mechanical planarization (CMP) is a wafer-surface-polishing planarization technique based on a wet procedure that combines chemical and mechanical forces to fully flatten materials for semiconductors to be mounted on the wafer surface.

De novo or Salvage? Nucleotide Availability as a Driver of Bacterial Adaptation and Virulence

open access: yesMicrobiologyOpen, Volume 15, Issue 4, August 2026.
Bacterial pathogens survive in different host environments by switching between making nucleotides by de novo synthesis and scavenging them from the host. This flexibility supports growth and virulence making nucleotide metabolism an attractive therapeutic target.

Influence of Backside Surface and Subsurface Damage in Gallium Nitride Wafers on Facet Quality and Violet‐Emitting Laser Diode Performance

open access: yesphysica status solidi (a), Volume 223, Issue 14, 22 July 2026.
Backside thinning techniques critically influence GaN laser performance. Compared to lapping, grinding reduces subsurface damage depth fivefold and lowers wafer bow, while mechanical polishing eliminates subsurface damage entirely. These improvements directly translate to smoother cleaved facets and a nearly 40% reduction in laser threshold current ...
