Once you vapourize the silicon your only option is to replace the part damaged.

Hi tahir.muhammad_nabee,

You have exceeded the maximum allowed supply voltage. Then, the device is maybe damaged. Please, always check the datasheet for the electrical characteristics. You find information about the main supply in ''Absolute maximum rating'' part of relevant datasheet.
