    摘要: A method of self packaging an integrated circuit chip (10) on a printed circuit board (14) where conductive leads (16) form an electrical connection with interconnect leads (12) on the printed circuit board (14). A centering frame (22) placed on the printed circuit board serves to align the leads (12 and 16). A cooling cap (34) which dissipates heat from the integrated circuit chip (10) is placed over the centering frame (22) and integrated circuit chip (10). In one embodiment, the leads (12 and 16) form a pressure fit and the cooling cap (34) forces the pressure-fit electrical connections. In another embodiment, the leads (12 and 16) make rubbing contact with each other.

    摘要: A circuit assembly including a plurality of integrated circuit chips wherein electrical interconnections between chips at a relatively large distance from each other are accomplished by a conductor bus comprising a first section including conductors running adjacent and parallel to each other for a distance substantially equal to an integral number of half wavelengths of the base frequency of signals of the circuit and second sections including conductors which sharply diverge toward associated integrated circuit chips for electrical connection therewith.

    摘要: A method for storing data in an archival memory semiconductor target by providing a masking layer of a conductive material on the surface of an insulative layer upon the top surface of a semiconductor substrate; the material layer is assigned a two-dimensional array of possible data storage sites. The masking layer at those storage sites at which a first binary value is to be stored, is melted; the selected material is one which, at the melting temperature thereof, does not wet the surface of the chosen insulator whereby apertures are formed by the writing electron beam in the masking layer, at energy levels insufficient to evaporate the masking material. The writing beam energy is reduced at the data sites at which data bits of the remaining binary value are to be stored, and does not melt the masking material thereat. The data stored in the target is read by sweeping an electron beam of relatively low energy across the array to induce a flow of current from the semiconductor substrate and of magnitude dependent upon the presence or absence of an aperture in the masking layer at the data site interrogated.
