Title: Clamp ring
Inventor: MORIYA SHUJI

Filed: 1996-07-12
Abstract: PROBLEM TO BE SOLVED: To prevent peel-off of a deposit over a long period of time by forming a clamp ring using a porous Al2 O3 sintered body having a specified crystal grain size. SOLUTION: A clamp ring 12 is made of a porous Al2 O3 sintered body, and the crystal grain size thereof is set to 20μm or greater on the average. By thus causing the crystal grain size of the porous Al2 O3 sintered body to be greater than in the conventional technique, a deposit is likely to be trapped in a grain boundary portion, and an anchor effect for the deposit is increased, thus making the deposit unlikely to be peeled off. A semiconductor wafer W is held on a lower electrode 11 by this clamp ring 12. In this state, an etching gas is supplied into a vacuum processing chamber 10 via a gas supply tube 14 and fine pores 13b of an upper electrode 13 from a gas source 15, and a high-frequency voltage is applied to at least one of the lower electrode 11 and the upper electrode 13, thus forming a plasma of the etching gas and carrying out etching.

Abstract: PURPOSE:To make a refresh characteristic satisfactory and to reduce the probability of causing a malfunction by turning a switching transistor to be in a nonconductive condition in a state in which the potentials of a bit line and a plate line are turned to the substrate potential and the equipotential of a semiconductor substrate, respectively. CONSTITUTION:After the performance of access to a memory cell 11 is operated, the driving signal transmitted from a word line 4 is stopped, and the switching transistor of the memory cell 11, for example, an MOS type transistor 17, is turned to be in the nonconductive condition. At that time, the potentials of a bit line 16 and a plate line 13 are turned to the substrate potential and the equipotential of the semiconductor substrate, respectively.
