    摘要: A process comprising removing surface layer materials from the wafer by inducing micro-fractures in the surface using a rotating pad and an abrasive slurry until all of the surface layer materials are removed; and chemically etching the surfaces of the wafer until all micro-fractures are removed therefrom. Edge materials are removed by abrasive tape. Wafer thickness reduction during recycling is less than 30 microns per cycle. One of the front and back surfaces of the wafer substrate is polished, any dots or grooves being on the non-polished side. The abrasive slurry contains more than 6 volume percent abrasive particles, and the abrasive slurry has a viscosity greater than about 2 cP at ambient temperature. The preferred pad comprises an organic polymer having a hardness greater than about 40 on the Shore D scale, optimally a polyurethane. The pressure of the pad against the wafer surface preferably does not exceed about 3 psi. Preferably, the chemical etching solution contains potassium hydroxide. An acidic solution can then be applied to the wafer surface. The reclaimed semiconductor wafer can be a silicon wafer having a matted side having etch pits which does not exceed 20 microns in width, an average roughness not exceeding 0.5 microns and a peak-to-valley roughness not exceeding 5 microns. Any laser markings from the original wafer are present on the matted side of the wafer.

    摘要: Provided is a Polar modulation apparatus which compensates for output characteristics of a power amplifier. A data generator generates an amplitude component signal and a phase component signal. A phase modulator generates a phase modulated signal obtained by phase modulating the phase component signal. An adder adds an amplitude offset voltage to the amplitude component signal. A power amplifier which includes a first hetero-junction bipolar transistor, amplifies the phase modulated signal by using the amplitude component signal. A monitor unit monitors the power amplifier and outputs a monitor voltage. The control unit calculates the amplitude offset voltage according to the monitor voltage and outputs the calculated amplitude offset voltage to the adder. The monitor unit includes a second hetero-junction bipolar transistor and outputs a collector emitter voltage of the second hetero-junction bipolar transistor as the monitor voltage.
