## Abstract

A method of strengthening glass by ion implantation includes following steps. First, an ion implantation device is provided. The ion implantation device generates a plurality of positive ions and a plurality of negative ions. The positive ions and the negative ions are implanted into a glass substrate by the ion implantation device for strengthening the glass substrate.

## Claims
