Abstract: A semiconductor chip package using a chip constraint means is provided in the invention. The root cause for the warpage and stress of a semiconductor chip package under a temperature change is the CTE mismatch between the chip and substrate. The current inventive concept is to reduce the CTE mismatch by using a chip constraint means to constrain the thermal deformation of the chip. In one preferred embodiment, the chip constraint means comprises a chip constraint ring surrounding and bonding to the chip. In another preferred embodiment, the chip constraint means further comprises a chip constraint lid covering and bonding to the chip as well as bonding to the chip constraint ring. The overall CTE of the chip and the chip constraint means is to be relatively high when using a high CTE and high modulus of chip constraint means, reducing the warpage and stress of a flip chip package.
