New Equipment & Process Capabilities
DRIE and the DRIE Process Center
A new Deep Reactive Ion Etcher (DRIE), SPTS Rapier, has been installed and in service in the recently launched NFF-DRIE Process Center (Rm. 2223). This equipment was funded by the Research Grants Council Collaborative Research Fund (RGC-CRF) equipment grant 2016/17.

In order to enhance the NFF’s Deep silicon etch capabilities, the NFF has launched a new DRIE Process Center in August 2018. In the Center, there are two DRIE etchers catering for different cleanliness levels. One of them is for non-standard DRIE etching processes, which the NFF did not support previously. With this extended DRIE process capability, the NFF can now support the whole range of cleanliness levels for DRIE processes. Moreover, a P-10 Step Profiler and a Nikon optical microscope are in service at the Center for in-line measurements and sample inspections.
3-D Surface Profiler
A non-contact, high-speed and large-scanning-area Laser Surface Profiler (VK-X250K) from Keyence has been installed in the NFF Phase II laboratory. The profiler can significantly improve topological measurements of various substrates. Users can obtain their sample’s surface topographic images and analyze the acquired data within a very short time.
High-Resolution Optical Microscope
A high-resolution Nikon L200ND optical microscope has been installed in the NFF laboratory to facilitate a fast inspection after wafer processing.
Critical Point Dryer
A Tousmis Automegasamdri 915B Critical Point Dryer has been installed in the NFF Phase II laboratory for drying substrates fabricated with special structures after cleaning and rinsing.
