Classification: CPC H | IPC H

Claim 0:
1. A chip structure, comprising:
a first substrate having a first inclined sidewall;
a second substrate located on a lower surface of the first substrate, and having an upper portion and a lower portion, wherein the lower portion extends from the upper portion, and the upper portion is between the first substrate and the lower portion and has a second inclined sidewall;
a bonding layer between the first substrate and the second substrate, wherein the first inclined sidewall of the first substrate, an inclined lateral surface of the bonding layer, and the second inclined sidewall of the upper portion of the second substrate have a same slope;
a conductive via in the lower portion; and
a redistribution layer extending from a top surface of the first substrate to a top surface of the lower portion of the second substrate sequentially along the first inclined sidewall and the second inclined sidewall, and electrically connected to the conductive via.
