Semiconductor packages

The invention discloses a semiconductor package. The semiconductor package may include a package substrate, a semiconductor chip, which is mounted on the package substrate to have a bottom surface facing the package substrate and a top surface opposite to the bottom surface, a mold layer provided on the package substrate to encapsulate the semiconductor chip, and a heat dissipation layer provided on the top surface of the semiconductor chip. The mold layer may have a top surface substantially coplanar with the top surface of the semiconductor chip, and the top surfaces of the semiconductor chip and the mold layer may have a difference in surface roughness from each other. 公开了种半导体封装件。半导体封装件可以包括：封装基底；半导体芯片，安装在封装基底上以具有面对封装基底的底表面和与底表面相对的顶表面；模制层，设置在封装基底上以包封半导体芯片；以及散热层，设置在半导体芯片的顶表面上。模制层可以具有基本上与半导体芯片的顶表面共面的顶表面，半导体芯片的顶表面和模制层的顶表面可以具有彼此不同的表面粗糙度。
