Title: Semiconductor memory device
Inventor: NAKAYAMA AKIO
IPC: H01L27/10
Filed: 1990-02-07
Abstract: PURPOSE:To obtain a semiconductor memory device where a DRAM can be elongated in memory holding time by a method wherein a back gate bias voltage applied to a P-type silicon substrate through an N well is set different from a back gate bias voltage applied to a P well in volt. CONSTITUTION:A back gate bias voltage generating circuit VBB2 28 of a semiconductor memory device generates a back gate bias voltage VBB2 applied to a P-type silicon substrate 1, and memory cells 16-24 are formed on the P-type silicon substrate 1. As a shallow back gate bias voltage VBB2 is applied to the memory cells, a reverse leakage current flowing between an N<+> diffusion layer 21 and a P-type silicon substrate 1 of a memory cell capacitor becomes small. Electrons are injected into a P well 30 from an N<+> diffusion layer 12 when a negative surge is mixed into an input signal Vin, and eve if electrons are left unabsorbed by N<+> diffusion layers 11 and 14 to which a voltage of VCC is applied, they are absorbed into the N-well 30 to which VCC is applied so as not to reach to the memory cells. In result, the refreshing operation of a DRAM can be elongated in period.

Title: Pattern width detection and apparatus thereof
Inventor: YOKOI SADAAKI
IPC: G03F1/84
Filed: 1982-02-25
Abstract: PURPOSE:To inspect width irrespective of a pattern direction by judging fault only from the number of intersecting points with pattern through the scanning of a circular mask with a point on the pattern periphery as its center. CONSTITUTION:A binarized image 3 is formed by scanning a pattern to be inspected with a photo-electric converting scanner and by reading it, and it is then scanned by a detection mask 1, detecting the periphery thereof. A circular mask obtained from the designed reference value centering around the point for which the periphery is detected. When a pattern width satisfies the designed reference, it is considered to be sure that there are two intersecting points 4 detected by the scanning. If more intersecting points are found, it means that the width exceeds the designed reference value, which should be considered as a fault. According to this method, a pattern oriented to any direction can be detected. A number of intersecting points between a circular mask and pattern can be calculated at a high speed by inputting data X on the circular mask, obtaining exclusive OR's 7 of adjacent two points and by adding such outputs 8.
