Abstract: PURPOSE: To anisotropically etch silicon material by a method wherein the silicon material is irradiated with an accelerated hydrogen ion beam at a right angle to be selectively turned into an amorphous part and placed in an atmosphere of halogen fluoride to etch the amorphous part. CONSTITUTION: A crystalline silicon film 2 is deposited on a substrate 1, a photoresist mask 3 is formed thereon through a photolithography method, and an opening 4 is provided in the mask 3. Then, an accelerated hydrogen ion beam is made to irradiate the substrate 1 to form an amorphous region 5 in the opening 4 on the silicon film 2. The stubstrate 1 is placed in an atmosphere of halogen fluoride, and the surface 6 of the photoresist mask 3 is etched to make a part 7 recede. The amorphous region 5 is selectively etched to form a sheer hole 8. Finally, a gradually sloping part 9 is formed by isotropic etching. By this setup, a semiconductor element can increase reliability without forming by-products such as carbon and sulfur.

IPC: B29C47/66
Filed: 1988-12-28
Abstract: PURPOSE:To gradually and axially change the corrosion-resistant and wear-resistant characteristics of the inner surface of a cylinder so as to relieve the sharp difference between thermal stresses developed in different alloys in order to contrive to prevent cracks and separation of lining layer due to the difference between the thermal stresses in the alloys by a method wherein a plurality of different kinds of alloys of different properties are dividedly lined in an axial direction on the inner face of a cylinder body. CONSTITUTION:To base cylinder material 10, alloy lining 11, which is excellent in corrosion-resistant and wear-resistant characteristics, is applied to the region I by placing special importance on wear resistance; alloy lining 12, which is so corrosion- resistant and wear-resistant as to prevent a screw from wearing is applied to the region II and alloy lining 13 is applied to the region III by placing importance on corrosion resistance. By changing the qualities of the lining material at the inner surface of a cylinder in response to the functions of the respective parts of the cylinder, the wear of the portion, which normally wears excessively, at the inner surface of the cylinder is reduced. Further, since no much wear-resistant alloy lining as necessary is applied to the portion, which normally wears not so much, the wear of the screw, which slides on the inner surface of the cylinder, can be reduced, resulting in collectively prolonging the service life of the cylinder and the screw of a plastic molder.
