Photolithography

The Harry Diamond Laboratories, another predecessor organization to ARL, developed methods and devices in the mid-fifties to early sixties to lay down circuits, first on boards and later on silicon "chips" using photographic methods. This work, which was originally performed as a means to build gun-rugged electronics for artillery fuzes, was the genesis of both our printed circuit boards and our microelectronic devices/integrated circuits industries. HDL held many of the original patents in this area including three seminal patents on the masking processes and the step-and-repeat camera by which such devices are manufactured.
