Problems solved by technology

If the packaging substrate meets the requirements of miniaturization and the packaging substrate is too thin, not only the production workability of the packaging substrate is not good, but the packaging substrate is also prone to deformation due to the thickness of the packaging substrate being too thin and affected by environmental factors during the packaging process. Warped or damaged, causing problems such as defective products
[0003] In addition, touch panels or panels with sensing functions (such as biometric identification) are currently popular technology trends, but if users press the panels frequently for a long time, the touch elements located under the panels will fail

Description

technical field [0001] The present invention relates to a sensing chip packaging module and its manufacturing method, and in particular to a sensing chip packaging module of wafer size level and its manufacturing method. Background technique [0002] The sensing device of the chip package with sensing function is easily polluted or damaged during the traditional manufacturing process, which reduces the performance of the sensing device, thereby reducing the reliability or quality of the chip package. In addition, in order to meet the trend of miniaturization of electronic products, how to reduce the thickness of the packaging substrate for carrying semiconductor chips in the packaging structure of electronic products is also an important issue in the research and development of electronic products. In the manufacturing process of the packaging substrate, it makes circuits on the thin wafer layer. If the packaging substrate meets the requirements of miniaturization and the p...
