Abstract
A method of constructing a heater includes the steps of forming a sintered assembly including a ceramic substrate and a plurality of first slugs embedded therein, forming a functional element on one of opposing surfaces of the sintered assembly such that the functional element is connected to the plurality of first slugs, and forming a monolithic substrate in which the functional element and the plurality of first slugs are embedded.
Claims20
A method of constructing a heater comprising the steps of:
- hot pressing a ceramic powder and a plurality of first slugs and forming a sintered assembly including a ceramic substrate and the plurality of first slugs embedded therein;
- forming a functional element on one of opposing surfaces of the sintered assembly such that the functional element is connected to the plurality of first slugs;
- and
- forming a monolithic substrate in which the functional element and the plurality of first slugs are embedded.

A method of constructing a heater comprising the steps of:
- forming a sintered assembly including a ceramic substrate and a plurality of first slugs embedded therein;
- forming at least one trench into one of the opposing surfaces of the sintered assembly and into a part of the plurality of first slugs;
- and
- depositing a functional material into the at least one trench to form a functional element such that the functional element is connected to the plurality of first slugs;
- applying a material layer on the other one of the opposing surfaces of the functional element, the material layer being connected to the first slugs;
- and
- forming a monolithic substrate in which the functional element, the first slugs, and the material layer are embedded.
