Patent ID: 11887841
Assignee: SAMSUNG ELECTRONICS CO., LTD.
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 11:
12. The semiconductor package of claim 7, wherein:
the first main connection pad structures are arranged in a first main pad region, the first main connection pad structures have a first main pad density when viewed from the top of the first semiconductor chip, the second main connection pad structures are arranged in a second main pad region, the second main connection pad structures have a second main pad density when viewed from the top of the first semiconductor chip,
a difference between the first main pad density and the second main pad density is greater than a reference pad density,
the first dummy connection pad structures are arranged in a first dummy pad region, the first dummy pad region comprises n sub-dummy pad regions, n is determined by Equation 6,

(D_MP1−D_MP2)/(DCR)−1≤n<(D_MP1−D_MP2)/(DCR):  Equation 6,

wherein n is a natural number, DCR is the reference pad density, and
a k-th sub-dummy pad region has a sub-dummy pad density according to Equation 7,

D_DPk=(n+1−k)/(n+1)*D_MP1+(k)/(n+1)*D_MP2:  Equation 7,

wherein D_DPk is a density of the k-th sub-dummy pad region, k is a natural number from 1 to n, D_MP1 is the first main pad density, and D_MP2 is the second main pad density.
