Title: Nonvolatile semiconductor storage device and its manufacture
Inventor: KATO JUNICHI
IPC: H01L29/788
Filed: 1999-11-05
Abstract: PROBLEM TO BE SOLVED: To obtain a nonvolatile semiconductor storage device in which data can be written highly efficiently. SOLUTION: A nonvolatile semiconductor storage device uses a semiconductor substrate 1 the surface of which contains a first surface region 11 at a first level, a second surface region 12 at a second level lower than the first level, and a stepped side face region 13 connecting the first and second surface regions 11 and 12 to each other. A floating gate 4 is partially faced to the side face region 13 through a first insulating film 3, and the other part of the gate 4 is partially faced to the second surface region 12 through the insulating film 3. A control gate 6 is partially extended onto the first surface region 11 while being insulated from the surface region 11.  Therefore, a powerful electric field is formed near the corner section between the side face region 13 and second surface region 12 and, the same time, a local powerful electric field is formed in a channel region due to the potential difference between the floating gate 4 and control gate 6. Consequently, the electron injecting efficiency into the floating gate 4 from the side face region 13 and second surface 2 is remarkably improved and the data writing speed is improved noticeably.

Abstract: PURPOSE:To perform high integration upon reduction in an area of an electric capacity memory cell by forming an amorphous high dielectric film having 100 or more of permittivity between two electrodes in the memory cell of a dynamic semiconductor memory. CONSTITUTION:When a lead zirco-titanate film is formed in a shape held between two electrodes vertically or laterally at a low temperature by an MOCVD method, a sputtering method or a coating glass method in an electric capacity memory cell of a dynamic semiconductor memory, an amorphous PZT film can be formed. The permittivity of the film becomes about 580, and permittivity equivalent to or more than 200-450 of permittivity of a crystallized PZT film is obtained. An insulating breakdown strength is high with the same permittivity, a leakage current is reduced, the thickness of the film can be reduced that much, and further electric capacity can be enhanced. A material which is normally called 'ferroelectric ceramic material' is formed in an amorphous film thereby to obtain high permittivity of the same degree as that of ferroelectric ceramics, its insulating breakdown strength is improved, its leakage current is reduced, and hence thickness of one layer can be reduced, and electric capacity can be increased.
