摘要:
An electric image recording camera includes an imaging device (2) which converts optical information received through a lens (1) into an electric signal, and a recorder (5, 6) which records the information of one frame read out from the imaging device (2). An optical shutter (15) can arbitrarily set for a period of time for the imaging device (2) to receive the optical information. Means (19) are provided for stopping the read-out operation of the imaging device (2) while the optical shutter (15) is open, whereby the exposure time can be varied at will.
摘要:
In manufacturing a field effect transistor, a pattern which has a wider upper layer (11, 18) and a narrower lower layer (12, 19) is formed at a gate electrode position. Using the pattern as a mask, first (2) and second (3) impurity regions are formed on both the sides of a gate region (4) by ion implantation. Subsequently, at least the lower layer (12, 15) is buried in a material (13, 16), such as an organic high polymer material, having a selectivity in etching characteristics with respect to the pattern material. After removing the lower layer (12, 19), an electrode material (15, 71) is embedded in the resulting hole (14) so as to form a gate electrode (7, 81).
摘要:
A semiconductor memory having a capacitor (1) formed by utilizing a groove (17) formed in a semiconductor substrate (10) and an insulated gate field effect transistor (2) and suppressing expansion of a depletion layer (201, 202) from the groove, and a method for fabricating the same are disclosed. An area occupied by each memory cell can be made very small and a distance between the memory cells can also be made very small, accordingly, high density integration is facilitated.
