Abstract:
1. A method of manufacturing a probe array comprising the steps of: a) bonding together a first substrate having a property of transmitting light and a second substrate comprising a high-refractive-index layer having a refractive index higher than that of said first substrate, an intermediate layer layered on said high-refractive-index layer and a supporting layer layered on said intermediate layer, in a condition in which said first substrate is in contact with said high-refractive-index layer; b) removing said supporting layer included in said second substrate; c) patterning by said intermediate layer exposed as a result of said supporting layer being removed; d) etching said high-refractive-index layer using the patterned intermediate layer so as to form a plurality of cone-like or pyramid-like projecting portions on said first substrate; and e) removing the patterned intermediate layer so that the probe array having the plurality of cone-like or pyramid-like projecting portions made from said high-refractive-index layer on said first substrate be obtained.
