Patent ID: 6940729

Claim:
A circuit module comprising: a base element CSP integrated circuit having first and second oppositely facing major surfaces, the first major surface having a plurality of base element contacts; a support element CSP integrated circuit having first and second oppositely facing major surfaces, the first major surface having a plurality of support element contacts, the base element CSP integrated circuit and the support element CSP integrated circuit being in a stacked disposition to orient their respective second major surfaces toward each other, whereby the plurality of base element contacts face away from the plurality of support element contacts; a flex circuit comprising one or more conductive layers, base element flex contacts connected to at least one of the one or more conductive layers, and support element flex contacts connected to at least one of the one or more conductive layers, the base element flex contacts being in contact with the plurality of base element contacts and the support element flex contacts being in contact with the plurality of support element contacts.
