IPC: H01L29/866
Filed: 1994-05-31
Abstract: PURPOSE:To prevent the fluctuation of the breakdown voltage of a semiconductor device by providing an intermediate-concentration impurity layer of a first conductivity and high-concentration impurity layers of a first and second conductivities constituting a P-N junction in the semiconductor device and a gate electrode between the intermediate- and high-concentration impurity layers of the first conductivity with a gate oxide film in between. CONSTITUTION:A gate electrode 4 is provided between an intermediate- concentration impurity layer 1 of a first conductivity and high-concentration impurity layer 21 of the first conductivity with a gate oxide film 2 in between so that the surface resistance value of a semiconductor substrate 11 of the first conductivity can be changed when a voltage is applied across the electrode 4. The breakdown voltage of a semiconductor device can be changed, because a diode constituted of a high-concentration impurity layer 22 of a second conductivity and the impurity layer 1 changes the resistance value of the substrate 11 between the impurity layers 1 and 21 to which a breakdown current flows. Therefore, the fluctuation of the breakdown voltage of the semiconductor device can be prevented.

Title: Method and device for cleaning substrate
Inventor: NAGANORI ATSUO
IPC: H01L21/304
Filed: 1998-04-28
Abstract: PROBLEM TO BE SOLVED: To properly clean the surface of a substrate, without damaging the metal at the surface of the substrate. SOLUTION: On a water W, wiring plugs 4 connected to metal wirings 1 and silicon oxide films 2 are exposed. The wiring plug 4 is formed by flattening a metal film 4a through metal CMP processing. Therefore, on the surface of the silicon oxide film 2, particles and metal contaminating materials are attached. A part of these materials is rigidly adhered (absorbed) to the surface of the silicon oxide film 2. Furthermore, a part penetrates into the inside of the silicon oxide film 2. For the water W, diluted buffered fluoric acid aqueous solution(BHF) is supplied as the cleaning liquid. Thus, the particles and the metal contaminating materials can be effectively removed by the action of the fluoric aid in the diluted BHF. Since the diluted BHF has weak acid property, the wiring plug will not be corroded excessively.
