The present invention relates to a photoresist stripper composition for manufacturing a display, and more particularly, to an integrated photoresist stripper composition which can be used in every process for manufacturing a display. More specifically, the photoresist stripper composition for manufacturing a display according to the present invention can be applied to all of transition metals and oxide semiconductor wirings, and has an excellent ability to remove modified photoresist after a hard bake process, and implant process, and a dry etch process have been performed. In particular, the photoresist stripper composition for manufacturing a display according to the present invention exhibits a corrosion inhibitory effect that has been further specialized for copper (Cu) wiring pattern edge portions which are susceptible to corrosion following dry-etching.

Photoresist stripper composition for manufacturing display

A method of correcting an output value of a geomagnetic sensor that recursively calculates a state estimate, an estimate gain vector, and an estimate error co-variance based on the output value of the geomagnetic sensor that is acquired sequentially and corrects the output value of the geomagnetic sensor based on the value includes acquiring a koutput value of the geomagnetic sensor, calculating a kestimate gain vector based on a k&#x2212;1estimate error co-variance and the koutput value, calculating a kstate estimate based on the calculated kestimate gain vector and the koutput value and a k&#x2212;1state estimate, calculating the kestimate error co-variance using the kestimate gain vector and a k&#x2212;1estimate error co-variance, and correcting the output value of the geomagnetic sensor based on the kstate estimate, wherein k is a natural number larger than 1.
