  • Patent number: 7081649
    Abstract: A technology for a semiconductor integrated circuitry allows each of the DRAM memory cells to be divided finely so as to be more highly integrated and operate faster. In a method of manufacturing such a semiconductor integrated circuit, at first, gate electrodes 7 are formed via a gate insulating film 6 on the main surface of a semiconductor substrate 1, and on side surfaces of each of the gate electrodes there is formed a first side wall spacer 14 composed of silicon nitride and a second side wall spacer 15 composed of silicon oxide. Then, in the selecting MISFET Qs in the DRAM memory cell area there are opened connecting holes 19 and 21 in a self-matching manner with respect to the first side wall spacers 14 and connecting portion is formed connecting a conductor 20 to a bit line BL.

  • Patent number: 3971615
    Abstract: A connector for forming a series electrical connection between opposing ends of a pair of insulation-covered wires comprises a lower body portion having a longitudinal groove and a pair of upper body portions connected to and superimposable upon the lower body portion. Each of the upper body portions has a longitudinal groove for receiving and maintaining one wire end within the groove in the lower body portion. Each of the upper and lower body portions contain formations for receiving a conductive connecting piece having a pair of opposed blade portions for piercing the insulation to contact each wire end for forming a series connection. Opposing ends of the groove in the lower body portion and the outer ends of the groove in each upper body portion are formed with a thin yieldable wall for resiliently holding each wire end.
