Claim 10:
11. A method for forming an apparatus for transporting semiconductor elements, comprising:
providing a mold, wherein the mold comprises a cavity contouring a shape of a bottom portion of the apparatus, wherein the bottom portion of the apparatus comprises a front wall, a rear wall, a bottom wall coupled to the front wall and the rear wall, and a pivotal pin structure extending from the rear wall and comprising:
a base support connected to the rear wall and comprising a sidewall; and
a shaft protruding from the base support and comprising first, second, third and fourth side surfaces, wherein:
the first and fourth side surfaces are connected to the sidewall;
the second side surface is connected to the first side surface; and
the third side surface is connected to the fourth side surface;

heating the mold to a first temperature;
heating a polycarbonate resin to a second temperature under a humidity level from about 30% relative humidity to about 85% relative humidity to convert such that the polycarbonate resin converts from a solid state into a molten state;
heating a barrel of a mold injection apparatus, comprising:
heating a front portion of the barrel to a third second temperature;

heating a middle portion of the barrel to a fourth third temperature; and
heating a rear portion of the barrel to a fifth temperature using a multiple-step heating process performed at different temperatures and durations;
flowing the polycarbonate resin through the barrel;
injecting the polycarbonate resin into the mold through a nozzle attached to the barrel to form a solid structure; and
cooling the solid structure.
