Method for fabricating a surface-mountable crystal resonator

A method for fabricating a surface-mountable crystal resonator, the method comprising the steps of:

• a) forming a piezoelectric crystal substrate to have a first major surface, a second major surface, and a first attachment area, wherein the first major surface and second major surface are substantially co-planar separated by thickness of the piezoelectric crystal substrate and are parallel to a first major axis and a second major axis and perpendicular to a third major axis, wherein the first major axis, the second major axis, and the third major axis are substantially perpendicular to each other, and wherein the first attachment area is substantially parallel to the first major axis and includes at least two extensions, each of the at least two extensions comprising a first extension surface and a second extension surface, wherein the first extension surface is planar and substantially at 45 degree angles with respect to the first major axis and the second major axis and substantially parallel with respect to the third major axis, and wherein the second extension surface is planar and substantially at 45 degree angles with respect to the first major axis and the second major axis and substantially parallel with respect to the third major axis, and wherein the first extension surface and the second extension surface are substantially perpendicular;
• b) forming, on the first major surface, a first predetermined electrode pattern;
• c) forming, on the second major surface, a second predetermined electrode pattern, wherein the first predetermined electrode pattern and the second predetermined electrode pattern form an active area of resonance;
• and
• d) forming, on the first attachment area, a first predetermined attachment electrode pattern, wherein the first predetermined attachment electrode pattern is electrically coupled to the second predetermined electrode pattern.
