Title: Mask forming method for x-ray exposure
Inventor: ONO SUMIO
IPC: G03F1/22
Filed: 1985-08-20
Abstract: PURPOSE:To provide a mask for X-ray exposure which can moderate the internal stress, by forming a buffer layer between the mask substrate member and the growth substrate, or on the mask substrate member. CONSTITUTION:Using gas having a composition different from that used when forming an upper layer film (SiN serving as a mask substrate member), a film similar in mechanical natural to the Si substrate is formed. Thereafter, the composition is varied continuously on step by step, and at last an SiN film with a given composition is formed. Using a film with a small stress other than SiN, for example PSG or NSG, etc., as a buffer film and putting it between the mask substrate member and the Si substrate, the stress can be moderated. Concretely, a buffer layer 12 is first formed on the Si substrate 11, and then an upper layer 13 is formed. Thereafter, back-etching forms a mask substrate 14 or 14'. At this time, the thickness of the buffer layer made such that the stress can be sufficiently moderated.

Title: Forming method of semiconductor crystal
Inventor: SAKAI AKIRA
IPC: H01L21/203
Filed: 1993-07-26
Abstract: PURPOSE:To grow a germanium epitaxial layer in a layer type without forming an island structure, by individually irradiating a silicon crystal substrate in a vacuum, with a germanium molecular beam and atomic state hydrogen. CONSTITUTION:A silicon substrate 11 is irradiated with a germanium molecular beam 12 and atomic state hydrogen 13, and germanium is grown on the silicon substrate 11. In this case, the silicon substrate 11 is heated, but surface diffusion of germanium atoms 14 is restrained, because simultaneously supplied hydrogen atoms are attracted on the germanium atoms 14 which have arrived the substrate surface from a molecular beam source. Hence the germanium atoms which arrived the growth surface of the silicon substrate 11 are instantaneously captured by the crystal layer, and epitaxially grown, so that island structure is not formed.
