Abstract
A microelectronic package includes a light sensitive microelectronic element having a front face including one or more contacts and a rear surface, and conductive leads having first ends connected to the one or more contacts and second ends connected to one or more conductive pads adjacent the light sensitive microelectronic element. The package also includes an at least partially transparent encapsulant covering the light sensitive microelectronic element, the conductive leads and the one or more conductive pads, whereby the one or more conductive pads are exposed on a surface of the encapsulant.
Claims16
A microelectronic package comprising:
- a light sensitive microelectronic element having a front face including one or more contacts and a rear surface;
- conductive leads having first ends connected to said one or more contacts and second ends connected to one or more conductive pads adjacent said light sensitive microelectronic element;
- an at least partially transparent encapsulant covering said light sensitive microelectronic element, said flexible leads and said one or more conductive pads, said one or more conductive pads being exposed on a surface of said encapsulant.
A microelectronic package comprising:
- an electrically conductive base having a cavity formed in a top surface thereof;
- a conductive pad adjacent said conductive base;
- a light sensitive microelectronic element disposed in said cavity, said light sensitive microelectronic element having a front face including a first contact and a rear surface including a second contact, said second contact being electrically connected to said conductive base;
- a conductive lead having a first end connected to said first contact and a second end connected to said conductive pad;
- an at least partially transparent encapsulant covering said light sensitive microelectronic element, said base, said lead and said conductive pad, said conductive base and said conductive pad being exposed on a bottom surface of said encapsulant, the bottom surface of said encapsulant defining the bottom of said package.
A microelectronic package comprising:
- a light sensitive microelectronic element having a front face including one or more contacts and a rear surface;
