Inventor: IIZUKA KANJI
IPC: H01L21/3065
Filed: 2005-12-20
Abstract: <P>PROBLEM TO BE SOLVED: To provide a method for controlling the positions and arrangement of quantum dots, and to provide a quantum dot semiconductor device using the method.  <P>SOLUTION: A first semiconductor ultrathin film layer or a natural oxide film is formed on a semiconductor substrate, and the first semiconductor ultrathin film layer or the natural oxide film is evaporated locally using a scanning-type tunnel microscope and/or a scanning-type electron microscope to make a hole until the surface of the substrate is exposed. This process is repeated to prepare a periodical array of holes. Thereafter, after a second semiconductor ultrathin film is grown epitaxially, the first semiconductor ultrathin film layer or the natural oxide film remaining on the semiconductor substrate is evaporated with the second semiconductor ultrathin film by heating. Finally, a third semiconductor ultrathin film is grown epitaxially to form quantum dots whose positions and arrays are controlled. Further, a semiconductor light/electronic device which has the quantum dots whose positions and arrays are controlled in an active layer provides new device characteristic.  <P>COPYRIGHT: (C)2007,JPO&INPIT

Title: Method for controlling mask profile for forming reading sensor
Inventor: CONTRERAS RICHARD J
IPC: H01L21/3065
Filed: 2006-01-10
Abstract: <P>PROBLEM TO BE SOLVED: To provide a method for forming a magnetic reluctance sensor which avoids a shadowing effect of a mask structure during sensor formation.  <P>SOLUTION: A light-sensitive mask 510 is formed to cover a desired sensor are therewith, and reactive ion etching (RIE) is performed to transfer a pattern of the light-sensitive mask 510 onto a low order ARC layer 508. An RIE is performed with platen power of a comparatively high value. Higher platen power increases ion irradiation to a wafer. With this, physical (namely, mechanical) components of material removal increases compared with chemical components. Thus, since the physical components of material removal increases, a removal rate of the light-sensitive mask material increases compared with an ion mill resistive mask. As a result, formation of a spherical or mushroom-like photo-resist mask is avoided. Therefore, a shadowing effect can be avoided during the subsequent manufacturing processes.  <P>COPYRIGHT: (C)2006,JPO&NCIPI
