Abstract
An acoustic probe includes a plurality of acoustic array components separated and spaced apart from each other. Each of the acoustic array components includes: an array of acoustic element circuits disposed contiguous to each other at a first pitch; a plurality of pads each corresponding to one of the acoustic element circuits and formed within a circuitry area of the corresponding acoustic element circuit, the pads being disposed at a second pitch; a plurality of interconnection bumps each corresponding to one of the pads and being disposed in electrical connection with the corresponding pad, wherein the interconnection bumps are disposed at a third pitch; and a plurality of acoustic transducer elements on the interconnection bumps. The acoustic transducer elements are disposed at a fourth pitch. At least two of the first, second, third, and fourth pitches are different than each other.
