GLASS SUBSTRATE HAVING CIRCUIT PATTERN AND PROCESS FOR PRODUCING THE SAME

摘要

The invention provides a process for producing a glass substrate (10) having a circuit pattern (26), which includes a circuit pattern formation step of forming a thin film layer (12) on a glass substrate and then irradiating the thin film layer with laser light (22) to form a circuit pattern on the glass substrate; a low-melting point glass deposition step of depositing a low-melting point glass (28) having a softening point of from 450 to 630 °C on the glass substrate having the circuit pattern formed thereon; and a sintering step of sintering the low-melting point glass to form a low-melting point glass layer (32) comprising the low-melting point glass sintered on the glass substrate having the circuit pattern formed thereon and to form a compatible layer (34) between the glass substrate and the low-melting point glass layer.
