There are a few other manufacturers, but Sony has pretty much cornered the market. Much in the same way Intel has when it comes to CPUs. I know Aptina[1] has made sensors used in smartphones in the past. And was also the initial manufacturer for sensors used by Nikon in their 1 series mirrorless cameras. Toshiba has manufactured some in the past, but sold their image sensor business to Sony[2] last year.
