Optoelectronic lens array with an integrated circuit

Claim 1

An integrated circuit optical system, said system comprising: an electronic integrated circuit device having circuit components therein at least including optoelectronic transducers such that there is at least a plurality of said optoelectronic transducers adjacent a first side of said electronic integrated circuit device; a radiation transmitting material means having at least a plurality of lens portions integrally therein at a first side of said radiation transmitting material means such that electromagnetic radiation transmitted both through a second side of said radiation transmitting material means and through said lens portion is at least in part altered in direction of travel as a result of being transmitted through said lens portion, each said lens portion having an optical axis; and a bonding means, in addition to said electronic integrated circuit device and said radiation transmitting material means, bonding said radiation transmitting material means at said second side thereof to said integrated circuit device at said first side thereof such that said optical access of each said lens means is substantially centered with respect to a corresponding said optoelectronic transducer so that any deviation from being centered is less than approximately two micrometers.

Claim 20

A method for providing a monolithic integrated circuit chip optical system, said method comprising: fabricating a monolithic integrated circuit chip having a plurality of optoelectronic transducers therein adjacent a major surface of said monolithic integrated circuit chip; forming a lens means having a plurality of lens portions therein each capable of directing at least some of any electromagnetic radiation impinging thereon along a selected optical path; and joining said monolithic integrated circuit chip with said lens means by bonding said lens means to said major surface of said monolithic integrated circuit chip such that said directing of at least some of said electromagnetic radiation results in said electromagnetic radiation reaching said optoelectronic transducers, with said bonding being accomplished by use of a substantially transparent adhesive located between said lens means and said major surface of said monolithic integrated circuit chip which transparent adhesive reaches a desirable bonding strength substantially only through electromagnetic radiation impinging thereon.

Claim 21

A method for providing a monolithic integrated circuit chip optical system, said method comprising: fabricating a monolithic integrated circuit chip having a plurality of optoelectronic transducers therein adjacent a major surface of said monolithic integrated circuit chip; forming a lens means having a plurality of lens portions therein each capable of directing at least some of any electromagnetic radiation impinging thereon along a selected optical path; and joining said monolithic integrated circuit chip with said lens means by bonding said lens means to said major surface of said monolithic integrated circuit chip such that said directing of at least some of said electromagnetic radiation results in said electromagnetic radiation reaching said optoelectronic transducers, with said bonding being accomplished by use of a substantially transparent adhesive located between said lens means and said major surface of said monolithic integrated circuit chip which transparent adhesive reaches a desirable bonding strength substantially only through electromagnetic radiation impinging thereon.

Claim 24

A method for forming a mold from which a molded optical body can be obtained, said molded optical body formed from a radiation transmitting material and having at least a plurality of lens portions integrally therein each having a surface portion which is substantially spherical such that electromagnetic radiation transmitted through a said lens portion is at least in part altered in direction of propagation, said method comprising: forming a substrate having a plurality of separated surfaces, each of a selected area and each of which comprises a material which is wettable by a primary molding material; providing a selected quantity of at least one primary molding material on at least one of said separated surfaces to provide a prepared structure; heating said prepared structure until said primary molding material flows to cover that separate surface upon which it was previously placed to provide a mold basis structure; encasing at least that portion of said mold basis structure having said separate surfaces with said primary molding material thereon in an encasing material to serve as a replicating means; and separating said mold basis structure and said replication means such that a said mold may then be obtained from said replication means.

Claim 25

A method for forming a mold from which a molded optical body can be obtained, said molded optical body formed from a radiation transmitting material and having at least a plurality of lens portions integrally therein each having a surface portion which is substantially spherical such that electromagnetic radiation transmitted through a said lens portion is at least in part altered in direction of propagation, said method comprising: forming a substrate having a plurality of separated surfaces, each of a selected area and each of which comprises a material which is wettable by a primary molding material; providing a selected quantity of at least one primary molding material on at least one of said separated surfaces to provide a prepared structure; heating said prepared structure until said primary molding material flows to cover that separate surface upon which it was previously placed to provide a mold basis structure; encasing at least that portion of said mold basis structure having said separate surfaces with said primary molding material thereon in an encasing material to serve as a replicating means; and separating said mold basis structure and said replication means such that a said mold may then be obtained from said replication means.
