Inventor: WATANABE TSUTOMU
IPC: G03F7/00
Filed: 1995-09-29
Granted: 2000-08-11
Abstract: A color filter having a plurality of color layers on the surface of a transparent substrate, at least one of the color layers having a defect of layer unflatness, which is produced due to unevenness caused by contamination with foreign matters is repaired by a simple, industrially advantageous method. The method includes the steps of (1) eliminating a defective part of the color layers to produce a blank there, (2) filling the blank with a negative type photosensitive composition containing a colorant, and (3) exposing the photosensitive composition to light emitted from the side opposite to the color layer-carrying surface of the substrate, followed by development to eliminate the photosensitive composition unexposed to light. The color filter repaired is used to fabricate multi-color display devices which are by no means inferior in display qualities to those fabricated using a color filter having no defect originally.

Granted: 2001-10-11
Abstract: A nonvolatile memory device includes two floating-gate-type memory arrays, e.g. a flash memory (11) intended to be used as a relatively permanent program memory and an E2PROM (13) intended to be used as a more frequently updated data memory. A single set of address lines (Ai) and a single set of data lines (Dj) are used for both read and write operations for both memory arrays. Address decoding means for accessing an addressed location of a selected memory array includes separate column decoders (31, 33) and data latches (23, 39) for each array, but also includes a shared row decoder common to both arrays. Row address latching circuitry (24) associated with at least the data memory holds a decoded row address for that memory array during a write operation so as to free the shared row decoder for use on one or more concurrent read operations for the other memory array, e.g. the program memory. Data I/O buffer circuitry (19) and sense amplifiers (17) are also shared by both arrays. Control logic (21), responsive to input control signals selecting one of the memory arrays (CEE, CEF) and selecting a read (OE) or write (WE) operation, controls (Ck, Vpp) the various elements of the device, including address (25, 27, 29) and data latches and select/driver circuitry (32, 34, 35, 37), to carry out the desired operations.
