In just two weeks, Brooks will set up shop at the 2012 Fuel Cell Seminar & Exposition. This year’s event will be held at the Mohegan Sun in Uncasville, Conn. Stop by booth 211 and say hello to me and other Brooks reps, as we talk about our ongoing innovations in flow instrumentation for fuel cell manufacturing, and demo some of our mass flow controllers. Contact me to schedule a demo of our mass flow controllers, and you’ll receive a 4 GB USB drive in the shape of a Brooks GF 40/80 Series MFC.
Many of our customers need to turn liquids into vapor to apply a treatment to an item, or to use vapor as an ingredient to create something. Some specific examples include MOCVD, Atomic Layer Deposition, or Vacuum Polymer Film Deposition. Generating vapor reliably is very difficult, and many users of vapor cobble their own vapor generation system together and assume everything is working as expected. Most of our customers currently using our vaporizer system began with their own creations, and changed to the Brooks system after encountering the results of their home-made designs such as: inconsistent yield, chamber pressure spikes, operating expenses that are higher than expected, inability to support changing vapor demand, or safety problems or concerns.
In this video, Ed Fisher provides an overview of one of the larger integrated direct liquid injection vaporizer systems that Brooks Instrument has completed. This fully-automated vapor generation solution provides methyltrichlorosilane (MTS) vapor blended with Hydrogen on demand – whenever and wherever the customer requires vapor. Whether it’s mounted in a cabinet or on a small metal plate, every Brooks vaporizer is configured to meet the exact needs of the application to provide:
Vapor On Demand: The unique method of vaporization used by Brooks provides the fastest on/off vapor flow response available. The dual vaporizer design in the video is also ultra-flexible; allowing the vapor output of two vaporizers to be sent to two different processes, or both vapor outputs can be combined and sent to either individual process whenever there is a spike in vapor demand.
Safe Vapor Generation: As shown in the video, the Brooks design uses color coded labels to identify the system locations that contain hazardous materials, and there are numerous electrical fail-safes and backup systems. The Brooks method of vaporization also does not require a vessel filled with a bubbling, hazardous chemical to generate vapor. All Brooks vaporizer designs are created to maximize operator and equipment safety.
Control of Vapor Costs: The ultra-fast on/off vapor flow control of the Brooks vaporizer minimizes the amount of vapor wasted in the scrubber that isn’t used in the process. The electrical design in the video extends the real-world operating life of the vaporizers, sensitive liquid precursors do not experience thermal decomposition, and additional instrumentation costs for vapor flow controllers are avoided.

As a vendor exhibiting at Intersolar you get to see the show from a little different perspective than the average show visitor. Through your interaction with numerous customers visiting your booth you start to get a sense of the mood of the attendees and the opportunities that exist in the solar industries.
My first observation is that I was glad Brooks Instrument participated in the Intersolar portion of the combined Semicon/Intersolar show. From a facilities perspective, the two venues for the shows almost reflected the state of the two industries. Intersolar is located in Moscone West, a new exhibit hall which features large windows that let in the sun and generates a positive atmosphere on the show floor. The solar industry is the future and these facilities reflect that optimism.
Did you ever look at a large expensive building covered in glass? That glass is usually coated with some exotic materials to reflect heat in either direction. Some glass manufacturers are even shipping self cleaning glass. If you look hard, some of those large glass panels have stripes on them. Builders and architects hate that; so do I.
The stripes are usually caused by variations in the thickness of the coating material causing light to reflect non-uniform angles. A glass coating company I recently visited was coating sample pieces and was struggling with that same problem. This glass company was vaporizing a super secret liquid precursor for coating glass. In this process the vapor traveled through a very hot slot (as wide as the glass) over hot moving glass where a surface reaction takes place causing it to bond with the glass.
I am proud to be leading the Brooks team at the upcoming Intersolar North America in sunny, beautiful San Francisco. I recently attended Intersolar in Munich and was impressed with how that show has grown to almost fill the huge new Messe in Munich. The halls were crammed with people even on a hot day for Germany, the Thursday session. Intersolar North America appears to be on the same growth trajectory.
Our decision at Brooks to participate in Intersolar NA is a reflection on how great the show was last year and the maturation of the photovoltaic industry. For many of the photovoltaic suppliers, their business models have gone from product development, market acceptance to that of an on-going business that needs to increase productivity using existing capital and continually reduce costs. This is the perfect environment for Brooks material handling products which have been proven in industrial and process industries for decades. Brooks prides itself on developing products that are designed for long term, stable operation which is what is required now for low cost photovoltaic production.
