Silicon DRIE Systems – Deep Reactive Ion Etching

SAMCO Inc. > Etching Systems > DRIE Systems

Product Lineup

Samco provides Silicon Deep Reactive Ion Etching (DRIE) systems for MEMS device fabrication and TSV via-hole etching.
Samco was the first Japanese semiconductor process equipment manufacturer to offer DRIE systems using the Bosch Process.
Our systems have competitive process capabilities, and the product lineup covers both R&D and production.
For high-volume device manufacturing, double process chamber option is available.

System Features

Samco’s DRIE Systems are designed to enhance process capability and maximize throughput.
Furthermore, the systems are designed to reduce the downtime for maintenance operation.

High-density ICP plasma source

ICP Coil for Silicon DRIE

High power ICP source generates a repeatable high density plasma and enables high-rate Si etching of max. 55 µm/min .

High-speed Gas Switching

High-speed Gas Switching

Fast gas switching (~ 0.1 sec) allows smooth sidewalls with less scallops.

Optional SiO2 Etch Kit

ICP Coil for SiO2 Etching

Optional ICP coil enables high-speed SiOetching.

Designed for Easy Maintenance

Designed for Easy Maintenance

Rotatable touchcreen enables the system status check during maintenance operations.

Wafer Size Adjustment

Wafer Size Adjustment

Adjustment kit enables processing of wafers with different sizes.

Throughput Booster

Throughput Booster for DRIE System

Before being transferred into the reaction chamber, the wafer picks up the wafer edge protection ring from within the “booster chamber”
