Integrated circuit package system with waferscale spacer
View Patent ↗An integrated circuit packaging system is provided including: a first device having a first backside and a first active side; and a waferscale spacer having an exact fit at all four corners adjacent to an edge of the first device and a recess along the edge of the first device.
1. An integrated circuit packaging system comprising:
a first device having a first backside and a first active side, the first device being a first integrated circuit die; and
a waferscale spacer on the first backside having an exact fit at all four corners including an edge that matches an edge of the first device, and a recess along the edge of the first device, the recess not extending to the corners of the edge of the first device.
2. The system as claimed in claim 1
further comprising:
a second integrated circuit die having a contact pad with the first integrated circuit die over the second integrated circuit die and the recess aligned to expose the contact pad.
3. The system as claimed in claim 1 further comprising:
a package cover on the first device and the waferscale spacer.
4. The system as claimed in claim 1 further comprising:
a substrate;
a second device, having a contact pad, over the substrate with the first device over the second device with the recess aligned to expose the contact pad; and
an electrical interconnect between the contact pad in the recess and the substrate.
5. The system as claimed in claim 1 wherein the waferscale spacer has different forms.
6. The system as claimed in claim 1 further comprising:
a second integrated circuit die having a contact pad with the first integrated circuit die over the second integrated circuit die and the recess aligned to expose the contact pad.
7. The system as claimed in claim 1 wherein the waferscale spacer is comprised of an organic or inorganic material.
8. The system as claimed in claim 1 further comprising:
a second integrated circuit device, having a second backside and a second active side with a contact pad thereon, with the first integrated circuit device over the second integrated circuit device with the recess aligned to expose the contact pad, wherein the first integrated circuit device and the waferscale spacer provides planar rigidity to the second integrated circuit device for thinning.
9. The system as claimed in claim 1 further comprising an electronic system having the integrated circuit package system.
