Strem offer re-usable bubblers for use in ALD and CVD

As reported by Strem in Cambridge Network: Strem in Ireland and the UK continues not only to provide a wide variety of high purity precursors and several cylinder options, but also strives to build ongoing relationships with its customers by offering fast refilling and cleaning services

Researchers investigating chemical vapour deposition (CVD) would certainly call this field of study a mature research area. The field has grown significantly, with the addition of single atomic layer deposition ALD, from the early days of the mid to late 1980s where precursors had to be synthesized in-house to then decompose by gentle (more or less gentle) thermal treatment.

Rapid developments associated with CVD/ALD derived materials can surely be associated with the ever increasing number of volatile organometallic and inorganic – some may consider them as simple coordination complexes- that are commercially available.

Applications ranging from high dielectric oxides or transparent conductive films within electronics to protective coatings for clothing. The materials include high purity silicon-containing reagents to volatile rare-earth precursors.

Strem has been involved in this field for quite some time and an extensive list of compounds are available for use in CVD/ ALD related chemistry. Customers' containers or custom bubblers/cylinders are designed to be compatible with commercial equipment. These easily connected units made of stainless steel, come pre-charged with your favourite material and represent a plug-and-play approach to the once tedious synthetic task of actually making and handling such volatile and often harmful materials.

Many universities and companies find they are unable to refill their bubblers purchased, but this is a service Strem UK can offer.
