Title: Sequence controller
Inventor: KUROKAYA NAOHIRO
IPC: G05B19/05
Filed: 1982-01-08

Inventor: KIM CHON-SU
IPC: H01L27/108
Filed: 1990-07-23
Granted: 1993-11-05
Abstract: The DRAM cell comprises a structure wherein a deep trench  is formed in a silicon wafer, a stacked trench  capacitor  is  formed around a silicon pillar, and a  vertical  transfer  transistor  is formed on top of the silicon pillar after  the  formation  of  the stacked trench capacitor. The transfer transistor is connected  to the storage capacitor through  a  selectively  doped  n+  diffused layer, and isolation between DRAM cells is formed by  the  trench. The  DRAM  cell  has  high  reliability   and   stable   operating characteristics and allows the cell to be used in the formation of a DRAM with a capacity that equals or exceeds 64 MB.

Title: Production of heavy metal carbides with high specific surface area
Inventor: LEDOUX MARC-JACQUES
IPC: B01D53/94
Filed: 1990-03-26
Granted: 1993-05-10
Abstract: Method for producing heavy metal carbides with high specific surface area, characterized in that a gas compound of said metal is reacted with a reactive carbon of high specific surface area of at least 200 m<2>g<-1> at a temperature comprised between 900 DEG C and 1,400 DEG C, and carbides thus produced.
