Abstract
An image capturing module according to the present invention includes a holder member, which accommodates therein a focusing lens for forming an image of a subject light on an image capturing chip attached on a substrate and is attached to the substrate to cover the image capturing chip, where the holder member is directly supported on a surface of the image capturing chip.
Claims20
An image capturing module, comprising:
- a holder member, which accommodates therein a focusing lens for forming an image of a subject light on an image capturing chip attached on a substrate and is adhered to the substrate to cover the image capturing chip,
- wherein a step portion of the holder member is provided as a height direction position determining section for the focusing lens and the surface of the image capturing chip, without interposing any other steps,
- the height direction position determining section is an all flat surface of the step portion, and
- the height direction position determining section contacts the image capturing chip only by surface contact such that no adhesive is interposed therebetween.
An image capturing module, comprising a holder member, where an image capturing chip is attached to a substrate and a focusing lens for forming an image of a subject light on the image capturing chip is accommodated inside a cavity portion on a back side, the holder member being adhered to the substrate to cover the image capturing chip by the cavity portion on the back side to make the inside of the cavity portion on the back side sealed or semi-sealed,
- wherein a step portion of the holder member is provided as a height direction position determining section from a bottom surface of the cavity portion, which is a lens accommodating reference surface, without interposing any other steps,
- the height direction position determining section is an all flat surface of the step portion, and
- the step portion provided inside the cavity portion on the backside is provided with the height direction position determining section for the focusing lens and the surface of the image capturing chip, the height direction position determining section contacting a top surface of the image capturing chip only by surface contact between the holder member and the image capturing chip such that no adhesive is interposed therebetween.
A method for manufacturing an image capturing module, comprising:
- a sensor unit forming step of attaching an image capturing chip to a substrate;
- a lens unit forming step of accommodating and fixing a focusing lens for forming an image of a subject light on the image capturing chip, inside a cavity portion on a back side of a holder member, the lens unit forming step and the sensor unit forming step being performed either in this order or in a reverse order;
- and
- a sensor unit and lens unit coupling step of allowing a height direction position determining section of a step portion provided inside the cavity portion on the back side to directly touch a top surface of the image capturing chip and covering the image capturing chip by the cavity portion on the back side, and further, in this state, adhering the holder member to the substrate to seal or semi-seal the cavity portion on the back side,
- wherein the step portion of the holder member is provided without interposing any other steps, and the height direction position determining section is an all flat surface of the step portion, and
- the holder member is supported by the image capturing chip only by surface contact between the height direction position determining section and the top surface of the image capturing chip such that no adhesive is interposed therebetween.
A method for manufacturing an image capturing module, comprising:

- a lens unit forming step of accommodating and fixing a focusing lens for forming an image of a subject light on the image capturing chip, inside a holder member, the lens unit forming step and the sensor unit forming step being performed either in this order or in a reverse order;
- and
- a sensor unit and lens unit coupling step of allowing a height direction position determining section provided in the inside, at a step portion of the holder member without interposing any other step portions, to directly touch a top surface of the image capturing chip and covering the image capturing chip, and further, in this state, adhering the holder member to the substrate to seal or semi-seal the inside,
- wherein the height direction position determining section is an all flat surface of the step portion, and
- the holder member is supported by the image capturing chip only by surface contact between the height direction position determining section and the top surface of the image capturing chip such that no adhesive is interposed therebetween.
