Abstract
Description
technical field
[0001] The present invention generally relates to the field of semiconductor technology, and in particular, relates to a semiconductor device and a manufacturing method thereof. Background technique
[0002] The semiconductor integrated circuit industry has experienced rapid growth. As the size of semiconductor devices continues to decrease, the requirements for the sealing ring on the periphery of the chip to prevent moisture and ions from entering the chip and prevent cracks from propagating into the chip are increasingly demanding. However, the protection effect of the sealing ring in the prior art is not ideal. Contents of the invention
[0003] In the semiconductor device and the manufacturing method thereof provided by the embodiments of the present invention, the sealing ring has a stronger protection effect.
[0004] The semiconductor device according to the embodiment of the present invention includes a semiconductor substrate, an integrated circ...

Embodiment Construction
[0051] Example embodiments will now be described more fully with reference to the accompanying drawings. Example embodiments may, however, be embodied in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of example embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and thus their detailed descriptions will be omitted.
[0052] Semiconductor devices are often provided with a sealing ring extending around the periphery of an integrated circuit area of the semiconductor device. A seal ring is usually a continuous ring of one or more metal layers. In one or more example embodiments, the seal ring may have one or more functions of providing protection from external moisture from entering integrated circuit components formed in the semiconductor...
