Thermal resistor fluid ejection assembly |
摘要 |
A thermal inkjet resistor includes a plurality of resistor elements, and an uneven nucleation surface having protruding ridges separated by recessed channels and formed as a top layer of the resistor structure to vaporize fluid when heated by the resistor elements, wherein a width of each protruding ridge corresponds with an associated resistor element underlying the nucleation surface. |
