Title: Top stagger type thin-film transistor array of amorphous silicon
Inventor: TANAKA SAKAE
IPC: H01L29/78
Filed: 1988-04-27
Abstract: PURPOSE:To prevent the generation of the disconnection of gate wirings by forming an amorphous silicon layer or amorphous silicon layer and silicon nitride layer broader than the gate wirings to the entire part of the lower layer of the gate wirings. CONSTITUTION:There are the gate wirings 4 which connect the gate electrodes 1 to each other and the source wirings 5 which connect source electrodes 2 to each other and intersect with the gate wirings 4 as the wirings. The amorphous silicon layer 6 and the silicon nitride layer 7 are formed to TFT (thin-film transistor) parts and are formed to the entire part of the lower layer of the gate wirings 4 so as to be broader than the gate wirings 4. The gate wirings are thereby prevented from crossing the amorphous silicon layer 6 or the amorphous silicon layer 6 and the silicon nitride layer 7 and, therefore, the disconnection of the gate wirings 4 is prevented and the yield is improved.

Abstract: PURPOSE:To always obtain a full scale dynamic range over an entire wavelength even when a base line is bent on any side, by parallelly moving an absorbancy curve at the time when a blank specimen is used in a required direction to set a correction base line. CONSTITUTION:A blank specimen is received in both of a specimen cells 5 and a control cell 6 and the transmitted lights through the cells are detected as currents by light detectors 7, 8 and, when said currents are processed by logarithmic converters 9, 10, the first differential amplifier 11 and an A/D converter 13, the absorbancy curve B0 of the absorbancy corresponding to an entire wavelength is stored in a memory 14. The memory content thereof is read and the value parallelly moving said curve by matching the level of the point largely deflecting on the side coinciding with a measuring purpose such as a positive side with zero is determined by a CPU 15 and applied to the second differential amplifier 12 through a D/A converter 16 to set a correction base line B2 to store the same in the memory 14. By this method, a full scale dynamic range is always obtained over an entire wavelength even when the base line is bent on any side.
