Abstract

1,012,856. Electric selective signalling; data storage elements. INTERNATIONAL BUSINESS MACHINES CORPORATION. May 14, 1963 [May 18, 1962], No. 18961/63. Drawings to Specification. Headings G4C and G4H. [Also in Divisions H1 and H3. The invention relates to the performance of logical operations on variables represented by the presence or absence and if present the physical condition of a layer of material, especially when the layer has been deposited by the thermal dissociation of a gas. Nickel or iron carbonyl gas or silicon or germanium iodide gas is passed into a chamber and caused to dissociate and deposit (or not) nickel, iron, silicon or germanium respectively at a selected location on a substrate by the local application or removal of heat. The heat may be applied by a focused light beam, an electron beam, a laser beam, or a heat radiating or absorbing junction in the substrate. A particular deposit may be removed by producing the inverse thermal condition at the location and passing the appropriate gas into the chamber, e.g. carbon monoxide in the case of deposited nickel, thus reversing the original chemical reaction. In performing logical operations, the presence or absence of the deposit constitutes one logical variable, a second variable being provided by the energization or not of reading means for detecting the deposit, and a third variable being provided by utilizing two possible states of a physical property of the deposit if present. The deposit may be detected photo-electrically either by non-transmission of light directed at the deposition location or by the resultant rotation of the plane of polarization of plane polarized light directed at the location. Alternatively, the deposit may be detected by its magnetic effect. The two states referred to may be positive and negative saturation on the magnetic hysteresis loop of the deposit, or the corresponding sense of rotation imparted to incident plane polarized light (Faraday Effect). The deposit may be solid or liquid. The substrate may carry a square matrix of said deposition locations.
