Take 40 nm as the dividing‑line. For mature process nodes 40 nm and above, batch‑tank cleaners are preferred. For advanced nodes below 40 nm, single‑wafer cleaners are mandatory. Wafer size determines equipment platform; throughput and budget are secondary factors. Once process node and wafer size are confirmed, most selection disputes can be resolved.
GV Aperture Batch-to-Batch Drift & Stability Control for Laser-Modified Wet Etching
2026-11-04
In TGV glass via fabrication, batch-to-batch aperture drift and unstable dimension after laser-modified wet etching are common yield bottlenecks. The root cause of aperture fluctuation does not solely lie in laser drilling or etching alone.
TGV Glass Via Wet Etching: Through Failure & Bubble Control with Vacuum Degassing
2026-11-03
In TGV glass via wet etching, incomplete penetration and trapped bubbles are core bottlenecks limiting yield. Mass production verifications show most through failures stem from bubble blockage instead of insufficient etchant concentration. This paper classifies bubbles into entrained air, reaction-generated gas and dissolved outgassing, clarifies their different impacts on penetration yield and via profile. A practical 4-stage programmed vacuum degassing workflow, equipment specifications, yield acceptance criteria and low-cost auxiliary improvements are provided to stably lift mass yield above 99.5%.
12‑inch Quartz Carrier Cleaning: Process Pain Points and Solutions
2026-11-02
Quartz carriers are core consumables for semiconductor wet cleaning and furnace processes, and they continuously accumulate four types of contaminants: particles, metallic ions, organics and fluoride deposits. An eight‑step wet chemical cleaning sequence is adopted.
