Title: Metal insulator semiconductor non volatile storage element
Inventor: OKUZUMI TETSUYA
IPC: H01L29/78
Filed: 1987-02-20
Abstract: PURPOSE:To make an occupied plane area small and prevent latchup due to a substrate current by forming the first gate electrode comprising a diffusion layer which is prepared at a semiconductor substrate. CONSTITUTION:As the second gate insulating film 3 is formed by oxidizing a single crystal silicon semiconductor substrate 1, its insulating film easily may form a good quality one that is better than that formed at the surface of polycrystalline silicon and also it is easy for its film 3 to make its thin film thinner than that of the first gate insulating film 5. In other words, capacitance C2 between a control gate electrode 2 and a floating gate 4 can be increased and then it is possible for this element to set capacitance C2 to a desired large value without increasing an area lapped by both gates 2 and 4. And a drain region 6, a source region 7, and a channel part 8 are formed in polycrsytalline silicon that grows on the substrate 1 through an oxide film. In the case of reading, a substrate current does not flow in the semiconductor substrate and no latchup phenomenon develops as well.

Abstract: PROBLEM TO BE SOLVED: To carry out solid-liquid separation of an object to be treated which is crushed by a disposer and treat the object to be treated by installing a compressing part to discharge the liquid matter out of the object to be treated by pushing down a partitioning wall toward a conveyer belt and compressing the object to be treated between the conveyer belt and the partitioning wall. SOLUTION: The object to be treated which is gathered to the root of a partitioning wall 5 is brought into contact with a first compressing part 8 and compressed by the partitioning wall 5 which is pushed down to release the liquid matter.
