摘要:
A method for producing a substrate for a recording head wherein a plurality of electro-thermal converting elements, a plurality of driving functional elements for respectively driving the electro-thermal converting elements and a plurality of wiring electrodes for respectively connecting each of the driving functional elements and each of the electro-thermal converting elements are formed on a supporting member of photolithography comprises forming the wiring electrodes by etching a material layer for the wiring electrodes while etchingwise removing a photoresist for masking the material layer for the wiring electrodes.

A method for forming a crystal, which comprises applying a crystal forming treatment on a substrate having a free surface on which a deposition surface (S NDS ) with a small nucleation density and a deposition surface (S NDL ) having a sufficinetly small area for crystal growth only from a single nucleus and having a greater nucleation density (ND L ) than the nucleation density (ND S ) of said deposition surface (S NDS ) are. arranged adjacent to each other, thereby growing a single crystal from said single nucleus.
