Title: Active matrix substrate and its manufacturing method
Inventor: HAMADA TSUTOMU
IPC: H01L21/336
Filed: 2001-08-01
Abstract: PROBLEM TO BE SOLVED: To provide an active matrix substrate and its manufacturing method in which large area of silicon remaining becomes a black point defect and small area of silicon remaining can be certainly detected by a detector even when the silicon remaining occurs in a manufacturing process of an active matrix substrate. SOLUTION: A Cr film 16 is formed in advance in a pixel electrode region large area of which is occupied by pixels simultaneously with formation of a source/drain electrode. Then an ITO film 7 is formed so as to be in direct contact with the Cr film 16 and the ITO film 7 is subjected to wet etching by using ammonium cerium (IV) nitrate (NH4 )2 Ce(NO3 )6 and nitric acid HNO3 . When the silicon remaining 24 occurs below the Cr film 16 by extending between wiring 16 and wiring 36 at this time, the Cr film 16 on the silicon remaining 24 remains due to galvanic action of an etching solution and thereby resistance between wiring is reduced and detection of short circuit between wiring is facilitated.

They respectively represent the gradient of a straight line, passing through the reference point and the adjustment point A and the gradient of a straight line, passing through the reference point and the adjustment point B. Then the absolute value of a distance dn, from each adjustment point to the reference point, = (input value at the reference point) -(input value at each adjustment point) is obtained. Then a change amount An at the adjustment point A, after the change between the reference point after the change and the adjustment point A is becomes An=dn×PA, and a change amount Bn at the adjustment point B after the change between the reference point after the change and the adjustment point B is expressed as Bn=dn×PB. Adding An, Bn to each adjustment point enables obtaining the adjustment point, after the change.
