Patent ID: 7586758

Claim:
A circuit module comprising: a base element CSP microprocessor integrated circuit having upper and lower major surfaces and a set of contacts on the lower major surface; a support element CSP memory integrated circuit having at least two major surfaces and comprising a set of contacts, the base element CSP microprocessor integrated circuit and the support element CSP memory integrated circuit being in a stacked disposition relative to each other; a flex circuit comprising a first conductive layer disposed at a first conductive layer level of the flex circuit and a second conductive layer disposed at a second conductive layer level of the flex circuit, the first conductive layer level having base element flex contacts and the second conductive layer level having support element flex contacts, the base element flex contacts at the first conductive layer level being in contact with the set of contacts of the base element CSP microprocessor integrated circuit and the support element flex contacts at the second conductive layer level being in contact with the set of contacts of the support element CSP memory integrated circuit; a heat transference element adhesively connected to the upper major surface of the base element CSP microprocessor integrated circuit, and the heat transference element is in thermal contact with a heat absorbing structure.
