Process for producing a circuit substrate. |
摘要 |
<p>A process for producing circuit substrate is prepared by preparing at least one ceramic greensheet containing glass and sinterable at a low temperature for forming the circuit substrate, and at least one unsintered transfer sheet unsinterable at a sintering temperature of the ceramic greensheet, printing a wiring pattern on the unsintered transfer sheet, stacking the unsintered transfer sheet on the ceramic greensheet to form a laminated body and thermocompressing the laminated body to form a compressed body, firing the compressed body at a sintering temperature of the ceramic greensheet to form a ceramic substrate, thereby preparing a fired body by transferring the wiring pattern on the unsintered transfer sheet to the ceramic substrate, and removing the unsintered transfer sheet from the fired body to prepare a circuit substrate. <IMAGE></p> |
