Substrate inside type module structure
View Patent ↗The present invention provides a module structure of substrate inside type comprising a first substrate with a concave structure. A chip is configured on the concave structure of the first substrate, with a first contact pad and a sensing area. A second substrate is disposed on the first substrate, with at least one through hole structure and a second contact pad. The first contact is coupled to the second contact pad via a wire. The second substrate includes a first portion embedded into the module structure, and a second portion extended to outside of the module structure. A lens holder is disposed on the second substrate, and a lens is located on the top of the lens holder. A transparent material is disposed within the lens holder or the second substrate. The lens is substantially aligning to the transparent material and the sensing area.
1. A substrate inside type module structure, comprising:
a first substrate, with a concave structure, wherein said concave structure is a partial structure of said first substrate having a bottom surface and a top surface, wherein said bottom surface has a thickness difference with said top surface;
a chip configured on said bottom surface within said concave structure, with a first contact pad and a sensing area;
a second substrate disposed on said first substrate, with at least one through hole structure, wherein said second substrate includes a first portion embedded into said module structure and a second portion extending to outside of said module structure, wherein said at least one through hole structure is formed in said first portion of said second substrate without filling electrical material and having an area for exposing said sensing area;
a second contact pad, formed on said first substrate or said second substrate, wherein said first contact pad of said chip is electrically connected to said second contact pad of said first substrate or said second substrate via a wire without bump; and
a lens holder disposed on said second substrate, and a lens located on said lens holder, substantially aligning to said sensing area.
2. The module structure of claim 1 , wherein said first substrate is adhered to said second substrate via a conductive layer or an adhesion layer.
3. The module structure of claim 1 , wherein said chip is adhered to said first substrate via an adhesion layer.
4. The module structure of claim 1 , wherein said lens holder is adhered to said second substrate via an adhesion layer.
5. The module structure of claim 1 , further comprising a transparent material configured within said lens holder or on said second substrate.
