InactiveCN1455271AIncrease the effective thicknessReduce residual stressOptical filtersWavelength-division multiplex systemsEngineeringTransition layer
The method includes two implementing modes. In the first mode, before cutting the work piece, the transition layer connects the assistant substrate to the glass substrate. In the second mode, an other work piece comprises one glass substrate with the thickness being thicker than the final expected thickness. Then, the unwanted part of the glass substrate is removed. The method of the two implementing modes increases the effective thickness of the work piece so as to reduce residual stress of the film filter plate finished product. Moreover, the risk of the film stack peeled off from the glass substrate is reduced when the work piece is cut.
