Abstract
A microsieve with a very uniform pore size of 260 nm and a pore to pore spa cing of 510 nm has been fabricated using multiple exposure interference lit hography and (silicon) micro-machining technology. The sieve consists of a 0.1 mu m thick silicon nitride membrane perforated with sub-micron diameter pores and a macro perforated silicon support. The calculated clean water flux is at least one to two orders higher than that of conventional inorganic membranes.
