Abstract

A camera lens module includes an image sensor and a sandwiched lens structure formed over the image sensor, the sandwiched lens structure including a layer lens between a first glass substrate and a second glass substrate, and a baffle formed between the layer lens and the first glass substrate or between the layer lens and the second glass substrate.

First claim

What is claimed is:

1 . A camera lens module comprising:
an image sensor; a sandwiched lens structure formed over said image sensor, said sandwiched lens structure comprising a layer lens between a first glass substrate and a second glass substrate, and a baffle formed between said layer lens and said first glass substrate or between said layer lens and said second glass substrate; and a top lens structure formed on said sandwiched lens structure, said top lens structure comprising: a top glass substrate; at least a top lens formed between said top glass substrate and said second glass substrate of said sandwiched lens structure.

2 . The camera lens module of claim 1 , further comprising a bottom lens formed between said sandwiched lens structure and said image sensor.

3 . The camera lens module of claim 2 , further comprising a spacer formed between said bottom lens and said image sensor.

4 . The camera lens module of claim 1 , wherein said baffle is formed on said first glass substrate.

5 . The camera lens module of claim 1 , wherein said baffle is formed under said second glass substrate.

6 . The camera lens module of claim 1 , wherein said baffle is formed on a surface of said layer lens.

7 . The camera lens module of claim 1 , wherein said baffle is formed of black photoresist (BPR).

8 . The camera lens module of claim 1 , wherein a material of said layer lens is UV or thermal resin.

9 . A camera lens module, comprising:
an image sensor; a sandwiched lens structure formed over said image sensor, said sandwiched lens structure comprising a layer lens between a first glass substrate and a second glass substrate, and a baffle formed between said layer lens and said first glass substrate or between said layer lens and said second glass substrate; a bottom lens formed between said sandwiched lens structure and said image sensor; and wherein said first glass substrate comprises an IR cut/pass filter disposed on a surface of said first glass substrate facing said bottom lens.

10 . The camera lens module of claim 1 , wherein said baffle formed between said layer lens and said first glass substrate or between said layer lens and said second glass substrate is thereby forming an aperture over said image sensor.

11 . A camera lens module, comprising:
an image sensor; a sandwiched lens structure formed over said image sensor, said sandwiched lens structure comprising a multi-layer lens between a first glass substrate and a second glass substrate, and a baffle formed in said multi-layer lens and over said first glass substrate or in said multi-layer lens and under said second glass substrate; and a top lens structure formed on said sandwiched lens structure, said top lens structure comprising: a top glass substrate; at least a top lens formed between said top glass substrate and said second glass substrate of said sandwiched lens structure.

12 . The camera lens module of claim 11 , further comprising a bottom lens formed between said sandwiched lens structure and said image sensor.

13 . The camera lens module of claim 12 , further comprising a spacer formed between said bottom lens and said image sensor.

14 . The camera lens module of claim 11 , wherein said multi-layer lens comprises:
a first layer lens formed on said first glass substrate; and a second layer lens formed on said first layer lens.

15 . The camera lens module of claim 11 , wherein said baffle is formed over said first glass substrate.

16 . The camera lens module of claim 11 , wherein said baffle is formed under said second glass substrate.

17 . The camera lens module of claim 11 , wherein said baffle is formed within said multi-layer lens.

18 . The camera lens module of claim 11 , wherein said baffle is formed of black photoresist (BPR).

19 . A camera lens module, comprising:
an image sensor; a sandwiched lens structure formed over said image sensor, said sandwiched lens structure comprising a multi-layer lens between a first glass substrate and a second glass substrate, and a baffle formed in said multi-layer lens and over said first glass substrate or in said multi-layer lens and under said second glass substrate; a bottom lens formed between said sandwiched lens structure and said image sensor; and wherein said first glass substrate comprising an IR cut/pass filter disposed on a surface of said first glass substrate facing said bottom lens.
