Patent ID: 7920329

Claim:
A wafer-level optical lens module comprising: a first plurality of embedded lens structures formed between two first substrates, each embedded lens structure being formed of two optically aligned first inner refractive surfaces formed on respective first substrates and a first refractive material provided between the two first inner refractive surfaces; a plurality of refractive surfaces formed on outer surfaces of the respective substrates, wherein the plurality of outer refractive surfaces are optically aligned with the plurality of embedded lens structures; a second plurality of embedded lens structures formed between two second substrates, each embedded lens structure being formed of two optically aligned second inner refractive surfaces formed on respective second substrates and a second refractive material provided between the two second inner refractive surfaces, wherein one of the first substrates is bonded to one of the second substrates; and a third plurality of embedded lens structures formed between two third substrates, each embedded lens structure being formed of two optically aligned third inner refractive surfaces formed on respective third substrates and a third refractive material provided between the two third inner refractive surfaces, wherein the other of the second substrates is bonded to one of the third substrates, and wherein the outer refractive surfaces are formed on outer surfaces of the other of the first and third substrates.
