Test & Research Infrastructure

Overview of the available test and research infrastructure

Cleanroom

A large part of the test and processing equipment is located within the UGent cleanroom on the campus Tech Lane Ghent Science Park. The cleanroom is an enviroment with a controlled level of contamination that is specified by the number of particles (e.g. dust) per cubic meter at a specified particle size. The low level of particles in the cleanroom is a requirement for the nano- and microfabrication of chips and systems.

Equipment for lithography (pattern definition)

EVG 620 double-sided mask aligner

The mask aligner is used to transfer a pattern to a photosensitive material by selective exposure (through a mask) to a UV radiation source. The equipment supports several modes (proximity, soft / hard / vacuum contact) and can also do bottom side alignment. It can also be used in nano-imprint mode, where the pattern is transferred by imprinting.

K&S Manual Wedge Bonder model 4523

Manual wedge bonding of:

  • aluminum wire: 18um and 32um, 30/45deg and deep acces wedges.
  • gold wire: 38um (deep acces) and 76.2x25.4 ribbon (deep acces).

This model offers the versatility to bond simple discrete devices, chip on board, up to complex hybrid, microwave devices. A bonding head with a deep access option and tail adjust system supports deep cavity microwave applications where tight control over the tail length is essential. With the small 18um wire capability the creation of short wires with low loops to support RF devices is possible. A manual Z mode allows operator control over looping and wire length, providing excellent resuslts for tight spaces or unusual loop requirements.
