SAMCO was the first of Japan's semiconductor process equipment manufacturers to obtain a Bosch Process license. Using our latest patented Tornado ICP® technology and harnessing the Bosch Process, SAMCO's DRIE systems have proven effective in deep, vertical, high-speed silicon etching for both R&D and manufacturing.
Benefits of SAMCO Si DRIE systems:
- Industry leading etch rates of over 50 μm/min
- High selectivity of over 250:1 (Si:Photoresist)
- Uniformity of ±5% or better (4, 6, and 8" wafers)
- High aspect ratio (greater than 40:1)
- Low scalloping, smooth sidewall profile (less than 0.1 μm scallops)
- Patented, dual frequency SOI anti-notch etching technology
- Unique "anti-tilt" feature that ensures high uniformity
- Electrostatic chuck and helium backside cooling (for wafer temperature control)
- ICP source can be modified for DRIE of SiO2
DRIE applications: MEMS (Micro Electro Mechanical Systems), 3D packaging, TSV (Through Silicon Via), and the manufacturing of ink jet printer heads, sensors, and medical devices such as μTAS.
