Abstract
The method includes the steps of: a) dividing a large-scale touch sensing pattern to be manufactured into multiple divisional patterns and producing multiple photomasks corresponding to the multiple divisional patterns; b) providing a substrate with a conductive layer; c) disposing a photoresist layer on the conductive layer; d) a first exposure process: forming an exposing divisional pattern and multiple first targets the photoresist layer; e) an adjacent exposure process: forming an adjacent exposing divisional pattern and multiple second targets, and adjacently connecting the adjacent exposing divisional pattern and the exposing divisional pattern originally on the photoresist layer; f) repeating the adjacent exposure process to form multiple adjacent exposing divisional patterns until a complete exposing pattern has been assembled; g) performing a developing process to the photoresist layer; and h) etching the conductive layer to form the large-scale touch sensing pattern on the conductive layer.
