Abstract

The invention provides an electrode plate and a semiconductor device, and relates to the technical field of semiconductors. The electrode plate comprises a plurality of heat dissipation elements and connecting ribs, the heat dissipation elements are arranged in an array mode, every two adjacent heat dissipation elements are connected through one connecting rib, the heat dissipation elements are polygonal, and acute angles are formed between the connecting ribs and the heat dissipation elements. The electrode plate and the semiconductor device provided by the invention have the advantage that the chip is not easy to damage.

Description

technical field [0001] The present application relates to the technical field of semiconductors, in particular, to an electrode sheet and a semiconductor device. Background technique [0002] Electrodes of semiconductor products provide conduction and heat dissipation functions for semiconductor chips, and the most cost-effective material for conduction and heat dissipation is copper. Some small-sized packages use copper materials as frames and electrodes. [0003] However, the expansion coefficient of the copper material is several times that of the semiconductor chip material. Due to the mismatch between the expansion coefficient of the electrode sheet and the semiconductor chip during the use process and product production process, it may cause the chip to expand during the thermal expansion and contraction process. Damage will directly affect the product qualification rate and product reliability. [0004] To sum up, in the prior art, there is a mismatch between the exp...
