Patent ID: 8273596

Claim:
Process for producing strip-shaped and/or point-shaped electrically conducting contacts on a semiconductor component like a solar cell, comprising the steps of: (a) applying a moist material forming the contacts in a desired striplike and/or point-like arrangement on at least one exterior surface of the semiconductor component; (b) drying the moist material by heating the semiconductor component to a temperature T 1 and keeping the semiconductor element at temperature T 1 over a time t 1 ; (c) sintering the dried material by heating the semiconductor component to a temperature T 2 and keeping the semiconductor component at temperature T 2 over a time t 2 ; (d) cooling the semiconductor component to a temperature T 3 that is equal or roughly equal to room temperature, and keeping the semiconductor component at temperature T 3 over a time T3; (e) cooling the semiconductor component to a temperature T 4 with T 4 ≦−35° C. and keeping the semiconductor component at temperature T 4 over a time T4; and (f) heating the semiconductor component to room temperature.
