Image sensor module
View Patent ↗The present invention provides an image sensor module. The image sensor module has a die formed on a substrate, the die having a micro lens area, a lens holder formed on the substrate and over the die, a lens formed in the lens holder. A filter is formed within the lens holder and between the lens and the die, and at least one passive device formed on the substrate and covered within the lens holder. Conductive bumps or LGA (leadless grid array) are formed on the bottom surface of the substrate.
1. An image sensor module, comprising:
a die formed on a substrate, wherein said die has a micro lens area formed thereon;
a lens holder formed on said substrate and over said die;
a lens formed in said lens holder;
a filter formed within said lens holder and between said lens and said die;
at least one passive device formed on said substrate and covered within said lens holder, wherein said passive device includes a capacitor, a resistor or an inductor;
a first LGA (leadless grid array) solder formed on the bottom surface of said substrate; and
a second LGA solder formed under said die,
wherein said image sensor module electrically communicates externally through said first LGA solder without a connector.
2. The module in claim 1 , wherein said die is connected to said first LGA solder via wires formed on said die.
3. The module in claim 1 , wherein said image sensor is a CMOS image sensor.
4. The module in claim 1 , wherein said image sensor is a CCD image sensor.
5. The module in claim 1 , wherein said substrate includes ceramic, glass, resin material, quartz, metal, alloy, plastic material or PCB (Print Circuit Board) material.
6. The module in claim 1 , wherein said filter is an IR filtering layer.
7. The module in claim 6 , wherein said IR filtering layer comprises TiO 2 or light catalyzer.
8. The module in claim 1 , wherein said first LGA solder comprises contact pads formed around the periphery area at the bottom surface of said substrate.
9. The module in claim 1 , further comprises a protection layer formed on the micro lens area of said die.
10. The module in claim 9 , wherein said protection layer comprises transparent materials.
11. An image sensor module, comprising:
a die formed on a substrate, wherein said die has a micro lens area formed thereon;

a lens formed in said lens holder;
a filter formed within said lens holder and between said lens and said die;
at least one passive device formed on said substrate and covered within said lens holder;
a first LGA (leadless grid array) solder formed on the bottom surface of said die; and
a second LGA solder formed on the bottom surface of said substrate,
wherein said image sensor module electrically communicates externally through said second LGA solder without a connector.
12. The module in claim 11 , wherein said die is connected to said second LGA via said first LGA.
13. The module in claim 11 , wherein said image sensor is a CMOS image sensor.
14. The module in claim 11 , wherein said image sensor is a CCD image sensor.
15. The module in claim 11 , wherein said substrate includes ceramic, glass, resin material, quartz, metal, alloy, plastic material or PCB (Print Circuit Board) material.
16. The module in claim 11 , wherein said filter is an JR filtering layer.
17. The module in claim 16 , wherein said IR filtering layer comprises TiO 2 or light catalyzer.
18. The module in claim 11 , further comprises a protection layer formed on the micro lens area of said die.
19. The module in claim 11 , wherein said protection layer comprises transparent materials.
