If I have drawn an IC. Are there any manufucters that you can go too tom implement it?
If you are looking for a semiconductor fabrication house, this begs the question: Approximately how many million units per year would you be paying for? 

The IC manufacture business does not generally do one-off designs, nor one-off fabrication runs. There are supposedly "boutique" semiconductor fab houses that do short runs, but if they really exist any more in the current economy, the cost for tooling and fabrication would be pretty steep.

On the benefit-of-doubt that your query is sincere though not well-researched, a clarification on what your design intends to achieve, and the budgets you are thinking of, might help provide some insight, or instead, point you to existing ICs, in supersmall sizes, that might serve your purposes well.
