Title: A method of manufacturing a polycrystalline semiconductor film by ion implantation
Inventor: OYOSHI KEIJI
IPC: H01L21/20
Filed: 1991-05-02
Abstract: A method of manufacturing a polycrystalline semiconductor film includes a film formation step of forming an amorphous semiconductor film (2) containing crystalline phases (3) on a substrate (1), and a crystal growth step of performing ion implantation in the amorphous semiconductor film (2) with incident ions (Si) with a range larger than the thickness of the amorphous semiconductor film (2). The acceleration energy of the implanted ions is set so that the projected range of incident ions becomes larger than the film thickness of the semiconductor film. A polycrystalline semiconductor film (4) having large and uniform grain sizes can be formed at a low temperature (Figs. 1a, 1b). The ion may be a semiconductor constituting element to be crystallized, a substrate constituting element or a rare gas element. In the specific examples an amorphous silicon film containing crystal phases is deposited by CVD on a glass substrate and this is then implanted by silicon ions. Two or more types of ion may be implanted and reacted to form a transparent compound, e.g oxygen or nitrogen ions which react with silicon ions to form SiO2 or Si3N4. The semiconductor film (2) may also be formed by performing ion implantation on an amorphous semiconductor film on a substrate to partially form crystalline phases (crystal nucleation). Some of the crystalline phases contained in the amorphous film may be converted to amorphous phases. e.g. by irradiation with an ion beam; by forming an SiO2 film serving as a masking film and carrying out the ion implantation on the exposed portions of the amorphous semiconductor film not covered with the masking film under the conditions of forming amorphous phases; or by carrying out ion implantation in the entire film under the conditions not causing crystal growth. <IMAGE>
