Title: Semiconductor device
Inventor: TAIRA MASAYUKI
IPC: H01L27/108
Filed: 1997-04-03
Abstract: PROBLEM TO BE SOLVED: To make it possible to form an interconnection having high reliability by readily and effectively relaxing the step difference between adjacent regions in a semiconductor substrate. SOLUTION: A polysilicon film FG for relaxing step differences is provided on a field oxide film 12 in a peripheral circuit portion PC, a lower side, along the boundary between a memorial cell array portion MA and the peripheral circuit portion PC, to considerably mitigate the step difference at the boundary between both regions MA and PC (PCA), resulting in a considerable relaxation or reduction of the global step difference in a BPSG layer 38. Accordingly, the global step difference in the vicinity of the boundary is rendered gentle and small, and therefore, exposure or processing of a photoresist at the time of photolithography can be performed in accordance with a designed pattern in the steps of making an interconnection. In addition, there is no occurrence of short circuiting and disconnection between the individual interconnections formed on the BPSG layer 38.  Further, because the polysilicon film FG for mitigating step differences is connected to a ground potential, there is no risk of generation of coupling noises.

Title: Laser writing type high-polymer liquid crystal composite sheet and method for plotting on the liquid crystal composite sheet
Inventor: CHIBA TORU
IPC: G02F1/137
Filed: 1993-04-27
Abstract: PURPOSE:To enable high-density plotting by a laser and to facilitate the formation of the composite sheet to a larger size by dispersing liquid crystals causing phase transition to a transparent state and a scattering state by a temp. change and laser absorbing dyestuff together into a high-polymer matrix sheet. CONSTITUTION:The liquid crystals 12 causing the phase transition to the transparent state and the scattering state by the temp. change and the laser absorbing dyestuff 13 are dispersed into the high-polymer matrix sheet 10. The laser absorbing dyestuff 13 is preferably dispersed into the high-polymer matrix sheet 10 and the liquid crystals 12. The phase transition from the transparent to the scattering state necessary for plotting is generated in the liquid crystals on the parts irradiated with a laser and near these parts by dispersing the laser absorbing dyestuff 13 together with the liquid crystals. The laser absorbing dyestuff 13 is considered to be generated not only in the liquid crystals 12 but in the high-polymer matrix as well in such a case. The laser is efficiently changed to heat and the phase state of the liquid crystal molecules is changed by the scattering state form, by which the precise plotting is considered to be executed.

Abstract: PURPOSE:To obtain an always good-quality machining surface with respect to variation in floating capacitance by providing plural capacitors which are connected in parallel or in series between a part across poles between a pole and a workpiece and a DC power source, and which can shift the number of elements.
