Reliable Rechargeable Baffled Boxes

Excellent thermal sources for depositing thin film of silicon monoxide.

The box is loaded with SiO before use (not exceeding the weight indicated for that box)
Bulk SiO is held in compartment(s) indirectly connected to the chimney
As the box is heated, the SiO vapor is forced to flow through a series of baffles before exiting at the chimney
Since there is no line of sight between the bulk material and the substrate surface, the deleterious effects of spitting or streaming on the depositing film are eliminate

Available in non-rechargeable and rechargeable—named to reflect the location of the initial charging or recharging
A rechargeable box can be filled through one or two lids while still mounted on its electrical feedthroughs in the vacuum chamber
A non-rechargeable box must be dismounted from its electrical feedthroughs and disassembled before charging or re-charging
Both styles offer long life and can be recharged many times
Designed with two evaporation plume directions—upward “vertical” or downward “inverted” (by turning either source on its side, a “horizontal” plume can be arranged)
