Title: Semiconductor device
Inventor: HOSHINO TAICHI
IPC: H01L21/8234
Filed: 1999-06-17
Abstract: PROBLEM TO BE SOLVED: To suppress electrostatic breakdown of an LSI and prevent bad influence on internal circuits even if a high-voltage input signal is received, by connecting an end of a pair of two diodes series-connected in mutually opposite direction to a pad while the other end is connected to a power source line, wherein the diodes are formed in a well region of an input protection circuit. SOLUTION: Because of the presence of diodes D1, D2 that are reverse biased in both directions between an input pad 5a and a power source line +VDD, an input signal can be received in the voltage range up to the voltage at which either of the diodes breaks down without being influenced by the bilaterally reverse-biased diodes. Clamping of the input signal is not generated with this configuration. In addition, since the diodes D1, D2 are formed in a well region W, the substrate is reverse biased, and the influence on the circuits formed in other regions can be suppressed. Moreover, breakdown of the diodes due to electrostatic breakdown voltage is predominantly taken place in the diodes D1, D2 in the well region W, and adequate electrostatic protection can be prepared.

Abstract: PROBLEM TO BE SOLVED: To provide a method for manufacturing a semiconductor, that maintains a wafer waiting for washing treatment after ending etching treatment in a vacuum state as much as possible, minimizes time when the wafer is in an atmospheric pressure state, and can suppress the occurrence of after corrosion on the wafer that stands by in a waiting chamber. SOLUTION: Remaining time T2 in a washing treatment is measured in advance according to the time T1 for purging a wafer by atmospheric pressure in a waiting chamber 13 and time required for washing the wafer in a washing chamber 12, and the wafer where etching treatment is completed in a vacuum chamber 11 is allowed to stand by in the chamber 13 before being carried to the washing chamber 12. At that time, the chamber 13 is maintained in a vacuum state, and the state of the chamber 13 is changed to an atmospheric- pressure state at timing when the atmospheric-pressure purge time T1 nearly coincides with remaining time T2.
