A SiC wafer is produced from a single crystal SiC ingot. A focal point of a pulsed laser beam having a transmission wavelength to the ingot is set inside the ingot at a predetermined depth from a flat surface of the ingot, the predetermined depth corresponding to the thickness of the wafer to be produced. The pulsed laser beam is applied to the ingot to thereby form a separation layer for separating the wafer from the ingot. The wafer is separated from the ingot along the separation layer, and a flat surface is formed by grinding an upper surface of the ingot as a rough separation surface left after separating the wafer, thereby removing the roughness of the upper surface of the ingot to flatten the upper surface of the ingot.

Organometal-containing acrylate or methacrylate derivatives and photoresists comprising the polymers thereof. Unlike conventional matrix polymers of photoresist, the polymers induce a difference in silicon content between exposed regions and unexposed regions of photoresists by releasing their silicon-containing side chains with the aid of acid in a chemical amplification manner. The difference in silicon content causes the exposed regions to be etched at a different rate from that of the unexposed regions under oxygen plasma. Thus, the photoresist material makes it possible to use a microlithographic process comprising a dry development step which can advantageously prevent the deformation or collapse of patterns which is aggravated as their aspect ratio increases, as well as the photoresist is economically more favorable than a top surface imaging system to which silylation on its top surface or a multi-level resist system to which wet development on its top layer must be applied, because the microlithographic process is very simple and no solvent is released.

In one embodiment, a beam pump, an articulated reciprocating counterweight extending above the effort of a class 1 lever on extended pitman arms above the lever effort at the tail bearing to structurally and continuously changes it's position in an air-arc to reduce lifting and lowering torque, by rigid-mechanical geometric re-positioning of the counterbalance effect to and fro, when the rotation is crank arms falling toward the well load, thus mechanically, continuously, favorably, and without friction re-positioning the counterweight either away from the load and fulcrum thereby increasing the counterbalance effect, or nearer to the load and fulcrum thereby decreasing the counterbalance effect, as is desirable to compensate the unbalanced downhole load, where the load in the lift direction exceeds the load in the return direction. The longer the extension of the pitman arm above the beam with the counterweight attached the greater is the counterweight effect of the counterweight deadweight.
