An integrated circuit is fabricated by micromachining a hexagonal array of cMUT elements on top of a substrate comprising a hexagonal array of CMOS cells. Each cMUT element overlies a respective CMOS cell in one-to-one correspondence. During layout of the mask for micromachining the cMUT layer, either the hexagonal pattern or the alignment key is rotated until an axis of symmetry of the hexagonal pattern is aligned with an axis of the alignment key. Later, when the mask is superimposed on the CMOS substrate, the alignment key on the mask is aligned with an alignment key on the substrate. This ensures that the cMUT elements formed by optical lithography will be matched to the CMOS cells.

A rapid-sampling stochastic scanning multiphoton multifocal microscopy (SS-MMM) fluorescence imaging technique enables multiparticle tracking at rates upwards of 1,000 times greater than conventional single point raster scanning. Stochastic scanning of a diffractive optical element may generate a 10×10 hexagonal array of foci with a white noise driven galvanometer to yield a scan pattern that is random yet space-filling. SS-MMM may create a more uniformly sampled image with fewer spatio-temporal artifacts than obtained by conventional or multibeam raster scanning.
