Title: Semiconductor manufacturing equipment
Inventor: YAMADA HIROAKI
IPC: H01L21/302
Filed: 1992-01-08
Abstract: PURPOSE:To make magnetic field intensity above a sample stand approach uniformly to desired magnetic field intensity, and enable uniform etching of a specimen, by magnetizing the sample stand provided with ferromagnetic substance so as to have suitable magnetic field intensity, by using a coil arranged on the periphery of an etching chamber, before microwave dry etching is performed. CONSTITUTION:Ferromagnetic substance 102 like iron and nickel is arranged on the outer peripheral part of a sample stand 101. When etching process is performed, coil magnetic field 105 which is slightly higher than the magnetic field to be applied during actual etching and has the same direction is previously applied by a coil 104. Magnetic field 106 having the same direction as the magnetic field during etching is left in the ferromagnetic substance 102 magnetized by the coil magnetic field 105 after it is eliminated. After that, when magnetic field is applied by the coil 104, the magnetic field 106 of the magnetized ferromagnetic substance 102 is superposed on the peripheral part of the sample stand 101, and the magnetic field intensity is increased. Further by changing the degree of the magnetization of the ferromagnetic substance 102, desired magnetic field intensity can be obtained during actual etching.

The position/ attitude information of a robot hand and sensor-A information area acquired at the time of the reference motion and the mixed test motion. Using the information groups acquired, modeling is performed for recognition errors. Then, a correlation analysis is carried out seeking kinetic information that has a strong proportional relation to the absolute value of the errors, identifying a conversion matrix between the robot hand and the sensor-A, and determines a regression line of the recognition errors and speed.  In addition, with the kinetic information as a parameter, the recognition errors are formed into an approximate function, so that system diagnosis is accomplished in a short time.
