Title: Dual cell plate structure DRAM mfr. - has insulation films and conductor packing consisting of materials with different etching properties
Inventor: KIM HONG SUN
IPC: H01L27/108
Filed: 1993-08-18
Abstract: The method involves producing a bit line contact (33) after polarisation of the exposed substrate face, by formation of conductor packing (29), so that the bit line contact is relatively stable. A fourth insulation film (28), the conductor packing (29) and a fifth insulation film (30) for the formation of a buffer are of materials with different etching properties. This allows defects on the surface of the semiconductor substrate (21) to be avoided during formation of the bit line contact. Over and above this the fifth insulation film remains to act as a buffer between word- and bit lines. ADVANTAGE - Results in reduced parasitic capacitance between bit line and word line, reduced short circuit formation between word line and bit line, while being simpler method of production.

Pref. a tubular shoulder (6), from the end face (5) of the roller mantle (1), is pref. concentric to the roller axis, extending towards the rear and over part of the roller mantle length. The shoulder (6) pref. has a drilling, expanding as a truncated cone towards the shoulder end, with a conical expansion angle matching the structure of the cone (7) at the end of the roller shaft (2). The shoulder (6) is pref. formed by an inner tube within the mantle (1), with a conical expansion to match the conical end of the roller shaft (2). The expansion shaft screw (10,11) is a screw bolt with a centering shoulder (14) from the head, an expansion shaft (10) over most of the bolt length, and a threaded section (11). The expansion shaft screw can also be stud screw with a leading threaded section, a dividing groove and a centering ring. Most of the screw length of the expansion shaft (11) has a hexagon to assist screwing with a further centering piece and trailing threaded section (10). The roller shaft (2) has a drilling (8) along its axis to take signal cables (15) with an extension of the drilling (8) into the axial drilling (12) of the expansion shaft screw (10,11,14). USE/ADVANTAGE - The heated floating roller is to carry and move linear yarn material, and the like. The mounting system prevents looseness between the roller mantle and the roller shaft and, on a repair or replacement, the roller is ready for use immediately after assembly.
