Abstract:
1. A boron-comprising ink, for a non-contact printing process, the boron-comprising ink comprising: boron from or of a boron-comprising material selected from the group consisting of boron oxide, boric acid, borates having a formula B(OR) a spread-minimizing additive that results in a spreading factor of the boron-comprising ink in a range of from about 1.5 to about 6; wherein for a non-contact printing process the boron-comprising ink has a viscosity in a range of from about 1.5 to about 50 centipoise and, when deposited on a semiconductor substrate, provides a post-anneal sheet resistance in a range of from about 10 to about 100 ohms/square, a post-anneal doping depth in a range of from about 0.1 to about 1 μm, and a boron concentration in a range of from about 1×10 19 to 1×10 20 atoms/cm 3 .
