Abstract:
A wet etching apparatus is disclosed. The apparatus comprises a first tank, containing a first wet etching solution; a filter, having a filter cartridge, connected to the first tank to filter out the impurities in the first solution; a second etching tank, connected to the filter and the first tank in parallel, containing a second solution; a reaction tank, connected to the filter, wherein having a wet etching reaction; an exhaust component, connected to the filter and the reaction tank in parallel; a first pump, delivering the first solution to the reaction tank through the filter; and a second pump, delivering the second solution to the exhaust component to exhaust the solution from the etching tank through the filter.
Abstract:
The invention discloses a stacked storage capacitor structure for a LTPS TFT-LCD comprising a processed substrate, a first storage capacitor and a second storage capacitor. The first storage capacitor comprises a first conductive layer, a second conductive layer and a first insulating layer therebetween. The stacked storage capacitor structure further comprises a third conductive layer including a first portion and an extended second portion. The second storage capacitor comprises the second conductive layer, the extended second portion of the third conductive layer and a second insulating layer therebetween.
