  • Patent number: 4672410
    Abstract: A semiconductor device has memory cells respectively located at intersections of bit and word lines arranged in a matrix form, each of the memory cells being constituted by a single insulated gate transistor and a single capacitor. One memory cell is formed in an element formation region defined by each of trenches arranged in a matrix form. The capacitor has an insulating film formed along part of a side wall surface of a trench formed in at least a direction of thickness of a semiconductor substrate and a conductive layer formed along the insulating film. The transistor has a gate insulating film adjacent to the capacitor and formed along a remaining portion of the side wall surface of the trench, a gate electrode formed along the gate insulating film, and a diffusion region formed in a major surface of the semiconductor substrate which is adjacent to the gate insulating film.

  • Patent number: 4630237
    Abstract: A read-only memory has memory cells each with a vertical metal oxide semiconductor field effect transistor and a bit line. The vertical metal oxide semiconductor field effect transistor has a gate electrode serving as a word line, a source, a drain, and a vertical channel region between the source and drain constituted by first and second diffusion layers. The gate electrode is formed on a side wall of a trench, which has a pair of side walls substantially perpendicular to a major surface of a semiconductor substrate of a first conductivity type and an interconnecting bottom surface substantially perpendicular to the side wall surfaces. The first and second diffusion layers of a second conductivity type are formed in an upper portion of the semiconductor substrate and in a bottom of the trench, respectively. The bit lines are formed in a predetermined pattern.

  • Patent number: 4608485
    Abstract: An automatic transfer transaction processing apparatus has a passbook/transfer card printing/reading section for issuing a transfer card printed with transfer information as the bank name, branch name, account number, item number and name of the account of the transferee and the name and phone number of the transferer or the name and account information of the transferer. The transfer card has a magnetic stripe for storing the transfer information. When this transfer card is inserted in the passbook/transfer card printing/reading section on a subsequent occasion, the section reads the transfer information therefrom, which is then processed by the automatic transfer transaction processing apparatus.
