Title: Manufacture of nonvolatile semiconductor memory device
Inventor: MIYAI YOSHIO
IPC: H01L29/788
Filed: 1995-01-26
Abstract: PURPOSE: To provide the manufacturing method of a nonvolatile semiconductor memory device (a split gate transistor) which can prevent a reverse tunneling phenomenon. CONSTITUTION: A sidewall protective film 2 which is composed of a silicon nitride film is formed on the sidewall of a floating gate electrode 111 and a silicon oxide film 105, and a polymer layer and a damage layer 128 are then removed by a wet etching method. That is to say, since the boundary between the lower edge part of the floating gate electrode 111 and the silicon oxide film 105 is covered with the sidewall protective film 2, an etchant does not creep into the boundary, and the silicon oxide film 105 is not etched. As a result, it is possible to prevent a reverse tunneling phenomenon, and it is possible to avoid a problem that data is written erroneously into a memory cell which is in a nonselection state.

The difference between the pressures measured at the points 10 and 11 in front of and at the rear of the expanding machine 1 is detected by a detecting means 12. When the difference exceeds a specified value, a generating motor 5 is started via a switch 6, on account of which the expanding machine 1 may conquer the mechanical loss and transmit the torque thereof to the generating motor 5. At the time of the interruption of the Rankine engine, the working pump 3 is stopped and when the difference between the detected pressures is reduced below the specified value, the generating motor 5 is also stopped. The Rankine engine may be thus smoothly started and interrupted.

Title: Developing device
Inventor: YAMANE HIDENOBU
IPC: G03G15/08
Filed: 1983-01-27
Abstract: PURPOSE:To perform clear development without fogging by arranging a sleeve near a photosensitive body and insulating electrically a conductive part which contacts a developer in a developer conveyance path other than the photosensitive body from a device body. CONSTITUTION:The development gap D between the sleeve 1 and facing photosensitive drum 4 is nearly as great as the thickness A of a toner layer on the sleeve 1, and narrowed down as much as possible. The development gap D and toner layer thickness A are both thin, so a line of electric force generated from an electrostatic latent image on the photosensitive body 4 reaches near-by toner particles in contact. The sleeve 1, hopper 5, specifying plate 6, etc., are insulated electrically from the main device body. Therefore, a local electric field which contributes to development operates on toner particles near the photosensitive body 4 at a picture part and is dispersed to toner particles near the picture part and the boundary surface of a nonpicture part. Therefore, no local electric field operates at the nonpicture part, where no fogging occurs, so that an excellent good-contrast toner image is obtained.
