Flip chip module with enhanced properties

A method for fabricating a flip chip module comprising:

• providing a carrier having a top surface;
• attaching a flip chip die to the top surface of the carrier by way of interconnects that extend from the flip chip die to the top surface of the carrier;
• filling space between the flip chip die and the top surface of the carrier with a first mold compound;
• applying a second mold compound onto the top surface of the carrier to encapsulate the flip chip die;
• thinning the second mold compound to expose a substrate of the flip chip die;
• etching the substrate of the flip chip die such that none of the substrate remains to provide a thinned flip chip die having an exposed surface at the bottom of a cavity;
• and
• applying a third mold compound to substantially fill the cavity of the thinned flip chip die.

A flip chip module comprising:

• a carrier having a top surface;
• a first mold compound residing on the top surface;
• a first thinned flip chip die residing over a first portion of the first mold compound and having a first set of interconnects extending through the first portion of the first mold compound to the top surface wherein the first portion of the first mold compound fills a region between the first thinned flip chip die and the top surface;
• a second mold compound residing over the carrier and in contact with the first mold compound and extending to a first die surface of the first thinned flip chip die;
• and
• a third mold compound covering a first exposed surface of the first thinned flip chip die, wherein the first thinned flip chip die comprises a first layer with no substrate over the first layer, such that the first die surface of the first thinned flip chip die in contact with the third mold compound is a top surface of the first layer.
