Si Deep Reactive Ion Etching (DRIE) Systems

By SAMCO Inc.

Samco was the first Japanese semiconductor process equipment manufacturer to provide Silicon Deep Reactive Ion Etching (DRIE) systems using the Bosch Process. We offer DRIE systems with a range of sample sizes and number of chambers for MEMS device fabrication and TSV via-hole etching. Our systems have industry-leading process capabilities, and the product lineup covers both R&D and production. For high-volume device manufacturing, a double reaction chamber specification is also available. Key Features & Benefits - Industry leading etch rates of over 50 μm/min - High selectivity of over 250:1 (Si:Photoresist) - Uniformity of ±5% or better (ø4, 6, and 8″ wafers) - High aspect ratio (greater than 100:1) - Low scalloping, smooth sidewall profile (less than 0.1 μm scallops) - Patented, dual frequency silion on insulator (SOI) anti-notch etching technique - Unique “anti-tilt” feature that ensures high uniformity - Electrostatic chuck and helium backside cooling (for wafer temperature control) - ICP source can be modified for etching of SiO2
