Title: Method of fabricating a semiconductor memory capacitor
Inventor: CHON YONG-KWON
IPC: H01L21/8242
Filed: 1991-09-13
Granted: 1994-05-25
Abstract: forming a cell transistor on a silicon substrate 1, and forming a bit line contact; forming a bit line using polysilicon 6 and refractory metal silicide 7, and depositing an oxide; forming a capacitor storage node contact, and forming a doped polysilicon 10 and depositing a first planarizing oxide 11 thickly; patterning the doped polysilicon layer 10 and the oxide 11 and depositing a nitride 9; forming a second planarizing oxide 11a and selectively removing the nitride 9, and then depositing a polysilicon 12 and third planarizing oxide 11b and etching back to the surface of the polysilicon, to form storage node; removing the planarizing oxides 11, 11a and 11b, and forming a dielectric layer 13 and a plate node 14, thereby simplifying the process and increasing the area of the storage node.

Title: Process for preparation of benzimidazole derivatives
Inventor: CHOE SU-CHANG
IPC: C07D235/10
Filed: 1991-10-22
Granted: 1994-03-05
Abstract: This is a new method of synthesis of benzimidazole derivatives of formula (I). In formula, Ra and Rb are same or different subst. group such as hydrogen, halogen, C1-4 alkyl, C1-4 alkoxy, phenyl, amine or un- and substituted piperazinyl; R1 is hydrogen, C1-4 alkyl, C3-7 cyclozlkyl or aryl; R2 is hydrogen, C1-4 alkyl, C1-4 hydroxyalkyl, amino, or aryl. This benzimidazole derivative is prepared by reaction of o-nitroaniline of (II) and alcohol (III) in the presence of palladium catalyst and in the hydrogen atmosphere. Additional solvent is needless but commercial solvent can be used if necessary.
