Abstract: A voltage regulator in a semiconductor memory has: a comparing unit including first and second bias current sources, for comparing an output voltage with first and second reference voltages under control of a first signal, the second bias current source being ON under control of a second signal; and a driver active element, coupled to the comparing unit, for outputting the output voltage. Before sensing operations, the output voltage is reset to the second reference voltage. During the sensing operations, the output voltage is maintained at the first reference voltage and the second signal is asserted for turning ON the second bias current source for raising speed of the comparing unit. After the sensing operations, the output voltage is reset to the second reference voltage.

Abstract: A voltage regulator as a stable power supply to internal circuits in a semiconductor memory device is provided. This regulator includes a comparing unit, a first driver transistor, a feedback unit, an auxiliary control unit, a first switch, a second switch, and a second driver transistor. The comparing unit compares a reference voltage with a feedback signal to control the first driver transistor and maintain the internal power supply at a stable level. The second driver transistor, controlled by the first and second switches responsive to a trigger signal corresponding abrupt current consumptions and the auxiliary control unit responsive to the comparing result, supplies sufficient and appropriate current to the internal circuits and prevents the internal power supply from excessive overshoot and drop-out.

Abstract: A wafer heater is provided, including a body also serving as a heat source, a ceramic ring on the body, and a buffer ring on the body. The buffer ring contacts with the ceramic ring, and has a top surface higher than that of the ceramic ring so that a wafer can be placed on the top surface of the buffer ring without contacting the ceramic ring. The thermal conductivity coefficient of the buffer ring is smaller than that of the ceramic ring. The product of thermal conductivity coefficient and top surface area of the buffer ring is also smaller than that of the ceramic ring.
