APPARATUS AND METHOD FOR USING SPACER PASTE TO PACKAGE AN IMAGE SENSOR |
摘要 |
A packaged image sensor assembly utilizes a spacer paste to control the height of a transparent window above an image sensor die to provide safe wire bond clearance. A dam structure is used to control the height of the transparent window. The dam may be formed either entirely from spacer paste or by depositing the spacer paste on an underlying patterned mesa. An additional encapsulant is provided outside of the dam to encapsulate wirebonds and provide additional protection from moisture permeation.
