Abstract: PURPOSE:To obtain the orienting agent for a liquid crystal cell which is large in the oblique orientation angle of a liquid crystal and has uniform coatability by incorporating a specific polyimide resin precursor and specific diimide compd. precursor as a compsn. for the liquid crystal orienting agent. CONSTITUTION:This compsn. contains the polyimide resin precursor having the repeating unit expressed by formula I (in formula I, R1 denotes an org. group constituting tetracarboxylic acid or the deriv. thereof; R2 denotes a divalent org. group constituting diamine) and the diimide compd. precursor expressed by formula II (in formula II, R3 denotes an org. group constituting tetracarboxylic acid or the deriv. thereof; R4, R5 denote an org. group constituting monoamine having an alkyl group of 6-20C or the deriv. thereof). The amt. of diimide compd. precursor expressed by formula II is used usually at 0.1-100wt.% of the polyimide resin precursor expressed by formula I. The oblique orientation angle of the liquid crystal is thereby increased and the uniform coatability is obtd. when the compsn. is coated on a substrate.

IPC: H01L21/027
Filed: 1990-04-06
Abstract: PURPOSE:To precisely align an exposure mask with a substrate surface and improve sizing accuracy of an opening pattern by optimizing thickness of a photoresist layer on an alignment mark region and a device region respectively. CONSTITUTION:A photoresist layer 3 of optimum thickness (tA) is applied on a surface of a substrate 9 with an alignment mark 2 formed on a scribe region. By using a mask 4 equipped with an opening 5 corresponding to the scribe region, irradiation 3 light for exposure is selectively applied to the scribe region. The layer 3 is developed under predetermined conditions. As a result, thickness of the layer 3 is reduced to tB on at least on the mark 2 and on a region in the vicinity of its periphery while thickness of a device region remains tA. The mark 2 is used to relatively align a mask 7 with the substrate 1 surface. The mask 7 is used to project (main exposure) a predetermined optic pattern comprising exposure irradiation light toward the layer 3. The layer 3 is developed (main development) under predetermined conditions. A resist mask is used to etch the substrate 1 surface exhibited from an opening pattern 9.

Filed: 1987-04-17
Abstract: PURPOSE:To detect only a seal print by painting out the inner part of a seal print contour after detecting the seal print contour, comparing a paint-out pattern and an original pattern, and detecting only a part where image element values are coincident. CONSTITUTION:An original pattern including a seal print read from a slit, etc., by a seal print reader 1 is displayed on a display means 7; by designating a part of the seal print of the original pattern on the display means by a designation means 8, a contour tracing part 3 is detected by the contour of the seal print. After this detection, the inner part of the seal print contour is painted out by a mask pattern memory 4, then the pattern is compared with the original pattern to detect only such a pattern that image element values of both are coincident with each other. In such a way, only the seal print can be accurately and rapidly detected with a simple operation irrespective of the shape, the dimension or the inclination of the seal print or even when an unnecessary pattern such as a stamp frame or a stain, etc., is close to the seal print, thereby the processing time can be shortened.
