METHOD FOR FORMING LAYER STRUCTURE ON SUBSTRATE

摘要

PROBLEM TO BE SOLVED: To improve a method of a conventional technique so that a thin brittle flat substrate can be subjected to a process for making and forming semiconductor elements such as solar cells within a desired limit and ought to be protected from breaking and deforming by using an inexpensive means.

SOLUTION: A brittle substrate 10 is coated with an inorganic ceramic material 12, and successively, the inorganic ceramic material is heat-treated for hardening and sintering.
