Removing segment of a metal conductor while forming printheads

A method of forming a printhead, comprising:

• forming a resistive material over a first metal conductor over a first dielectric, and over the first dielectric in an opening in the first metal conductor;
• forming a resistor, from the resistive material in the opening, and a stack, comprising the resistive material over the first metal conductor, while removing a portion of the resistive material and a portion of the first metal conductor to form an inclined surface of the first dielectric in a region between the resistor and the stack;
• forming a second dielectric over the resistor, the inclined surface of the first dielectric, and the stack;
• forming a second metal conductor over the second dielectric;
• and
• removing an inclined segment of the second metal conductor from an inclined portion of the second dielectric in direct physical contact with the inclined surface of the first dielectric.

A printhead, comprising:

• first and second resistors over a first dielectric;
• a second dielectric, comprising first and second portions respectively over the first and second resistors and an inclined portion over and in direct physical contact with an inclined surface of the first dielectric in a region between the first and second resistors;
• respective metal conductors respectively over the first and second portions of the second dielectric;
• and
• a third dielectric between the first and second resistors in direct physical contact with the inclined portion of the second dielectric, wherein opposing sidewalls of the third dielectric are respectively sidewalls of chambers respectively over the respective metal conductors.
