Title: Dry etching method
Inventor: SATO HITOAKI
IPC: H01L21/302
Filed: 1990-01-24
Abstract: PURPOSE:To etch and remove Al, an Al alloy film and a multilayer film of Al and high melting point metal, with high selection ratio in reference to organic mask material, by using mixed gas of Cl2, BCl3 and HBr. CONSTITUTION:Cl3 reacts with Al2 to form AlCl3, and the etching rate is very high. HBr increases the selection ratio in reference to resist 1, and forms AlBr3 to exhibit high etching rate of Al. BCl3 eliminates an Al2O3 film on an Al2 surface in the initial period of etching, and eliminates the resist during etching. Resist elimination component attaches on an Al side wall, and acts so as to give anisotropy. When mixed gas of Cl2 and HBr is selected as the etching gas, and etching is performed in a low pressure atmosphere at 20-0.1 mili Torr, the dry etching of a specimen using Al2 is enabled with high selection ratio in reference to mask material 1.

Title: Semiconductor device
Inventor: KAMIOKA HAJIME
IPC: H01L29/86
Filed: 1979-02-06
Abstract: PURPOSE: To obtain a reliable device by controlling the base resistance directly below the insulating film by means of a current that flows from the emitter electrode provided on the base area through an insulating film to the collector area.  
     CONSTITUTION: The n-type Si substrate 10 is made a collector area, the p-type base area 11 is formed and the emitter electrode 13 is provided on the area 11 through the SiO 2  film 12. When current flows between the electrode 13 and the substrate 10, electrons are injected into the base area by the tunnel effect, the base resistance is reduced, and the resistance between both base connecting areas 14, 15 can be controlled. In this way, since no emitter diffusion layer is required, the affection of the surface impurity concentration is less, the crystalization ability is good, a leak current is less, no deterioration of withstanding voltage takes place, and consequently a reliable device can be obtained.

When the viscosity is 200cps or less, it is not desirable because dropping immediately after coating occurs and, when 3,000cps or more, workability is deteriorated because the sprayability is lowered. Furter, when said thixotropy index is 3.5 or below, it is preferable because the dripping phenomenon immediately after coating is generated.
