    • PROBLEM TO BE SOLVED: To provide a method of forming an electronic device such as a MOS transistor and the like wherein relatively reduced cost and time-saving processing technology is achieved. SOLUTION: The method of forming an electronic device such as a MOS transistor and the like includes the steps of forming a plurality of semiconductor islands 31, 35 on a substrate 10, printing a first dielectric layer 60 on or over a first subset 31 of the semiconductor islands, and optionally printing a second dielectric layer 65 on or over a second subset 35 of the semiconductor islands. The first dielectric layer 60 contains a first dopant, and the (optional) second dielectric layer 65 includes a second dopant different from the first dopant. The dielectric layers 60, 65, semiconductor islands 31, 35 and the substrate 10 are sufficiently annealed to diffuse the first dopant into the first subset 31 of semiconductor islands and, if present, the second dopant into the second subset 35 of semiconductor islands.

    • 要解决的问题:提供一种形成诸如MOS晶体管等的电子器件的方法,其中实现了相对降低的成本和节省时间的处理技术。 解决方案:形成诸如MOS晶体管等的电子器件的方法包括在衬底10上形成多个半导体岛31,35的步骤,在第一子集上或第一子集上印刷第一介电层60 31,并且可选地在半导体岛的第二子集35上或之上打印第二介电层65。 第一介电层60包含第一掺杂剂,并且(任选的)第二介电层65包括不同于第一掺杂剂的第二掺杂剂。 电介质层60,65,半导体岛31,35和衬底10被充分退火以将第一掺杂剂扩散到半导体岛的第一子集31中,如果存在,则将第二掺杂剂扩散到半导体岛的第二子集35中。 版权所有(C)2008,JPO&INPIT
