    • A technique for trimming resistors and other passive circuit components buried in hybrid multilayer circuit structures. For example, resistors (13) are formed between two dielectric layers (11, 19) of a hybrid multilayer circuit structure (10). The multilayer circuit structure with the buried resistors is appropriately processed to provide a fired multilayer circuit structure. Trimming of the buried resistors is accomplished with a laser beam that cuts through dielectric material of the fired circuit structure to selectively remove part of the resistive material of the buried resistors. The values of the buried resistors may be tested with conductive elements (15, 17) that are conductively coupled to the buried resistors. The disclosed technique also contemplates the trimming of other buried passive circuit components such as capacitors, and further contemplates the use of other trimming methods such as abrasive, air jet, or water jet trimming.
    • 一种用于微调电阻和埋入混合多层电路结构中的其他无源电路元件的技术。 例如,电阻器(13)形成在混合多层电路结构(10)的两个电介质层(11,19)之间。 适当地处理具有埋入电阻器的多层电路结构以提供烧制的多层电路结构。 掩埋电阻器的修整通过切割烧结电路结构的介电材料的激光束来实现,以选择性地去除掩埋电阻器的电阻材料的一部分。 可以使用导电耦合到埋入式电阻器的导电元件(15,17)来测试掩埋电阻器的值。 所公开的技术还考虑了诸如电容器之类的其它被掩埋的无源电路部件的修整,并且进一步考虑使用其它修整方法,例如磨料,空气喷射或水射流修整。
