Embodiment Construction

[0044] Figure 1A to Figure 1E A schematic diagram of a manufacturing method of a light sensing module according to an embodiment of the present invention is shown. First, please refer to Figure 1A , providing a lens module 100 and a lens holder 200 . In this embodiment, the lens module 100 includes a plurality of lens layers 110 and a spacer layer 120 , and the spacer layer 120 is disposed between the lens layers 110 . That is, the lens layers 110 are connected to each other through the spacer layer 120 .

[0045] In detail, each lens layer 110 includes a transparent substrate 112 and an optical element 114 . In this embodiment, the transparent substrate 112 is, for example, a glass substrate, and the optical element 114 is, for example, a lens, such as a convex lens. However, in other unillustrated embodiments, the optical element 114 may also adopt the design of a concave lens, which depends on the needs and designs of users, and the present invention is not limited the...

Abstract

The invention relates to a manufacture method of an optical sensing module. The manufacture method of the optical sensing module comprises the following steps: (1) providing a lens module and a lens support, (2) configuring the lens module into the lens support, (3) measuring the effective focal length of the lens module in the lens support to obtain a measuring result, and (4) determining a relative position between an optical sensor and the lens module according to the measuring result and fixing the optical sensor and the lens module on the lens support.

Description

【Technical field】 [0001] The present invention relates to a manufacturing method of an optical module, and in particular to a manufacturing method of a photo-sensing module. 【Background technique】 [0002] With the trend of miniaturization and low price of modules of electronic products, the emergence of wafer level module (wafer level module, WLM) technology has attracted much attention. Wafer-level module technology can make electronic products use wafer-level manufacturing technology to miniaturize the volume of electronic products and reduce costs. For example, the application of wafer-level module technology to the production of lens modules can make the volume of the lens module much smaller than that of traditional lens modules, which is convenient for application in electronic devices such as notebook computers and mobile phones. on the camera module. [0003] A common wafer-level light sensing module includes a lens module and a light sensor disposed on the lens m...
