Disclosed is a method of forming a trench pattern in a ceramic green sheet for subsequently filling with a conductive paste resulting in a fully inlaid conductor pattern therefrom. Starting with a green sheet, a high contrast ink drawing of the desired conductor pattern is formed thereon. The drawing may be formed by direct printing on the green sheet or by first printing it on a flexible substrate such as paper and then transferring by xerography to the green sheet. Next, the green sheet is illuminated with an intense noncoherent light source to cause a high degree of absorption of the light energy by the inked areas and volatilization of the green sheet binder material thereunder, thereby forming a trench pattern conforming to the drawn pattern.
