Depending on what exactly its legal status is these days 
(https://en.wikipedia.org/wiki/MStar), you might either follow the below 
MIPS example of describing it as

"MediaTek Inc. (formerly MStar Semiconductor, Inc.)",

or you might extend above description as
"MStar Semiconductor, Inc. (acquired by MediaTek Inc.)" if it still exists.

Or accordingly "Xiamen Xingchen Technology Co., Ltd. (formerly MStar 
Semiconductor, Inc.)" if it was renamed to Sigmastar (in which case you 
might additionally reserve sstar prefix for Sigmastar while at it).

Here you do mention Sigmastar.
