Title: Method for manufacturing semiconductor device
Inventor: OH TAE KYOUNG
IPC: H01L21/336
Filed: 2005-12-30
Abstract: A method for fabricating a semiconductor device is provided to increase the total length of a channel by simultaneously forming a step gate and a recess gate by two recess processes. A first photoresist layer pattern is formed which defines a step gate region where an impurity junction region in the upper part of a semiconductor substrate(100) protrudes. A predetermined depth of the semiconductor substrate is etched by using the first photoresist layer pattern, and the first photoresist layer pattern is removed to form a step gate region. A second photoresist layer pattern is formed on the resultant structure, defining a recess gate region. A predetermined depth of the semiconductor substrate is etched by using the second photoresist layer pattern as a mask, and the second photoresist layer pattern is removed to form the recess gate region. A predetermined thickness of a gate oxide layer(140) is formed on the resultant structure. A stack structure of a gate polysilicon layer(150), a gate metal layer(160) and a gate hard mask layer(170) is formed on the resultant structure and is etched to form a gate pattern. The recess gate region can be formed at both sides of a step gate region having a type that the impurity junction region in the upper part of the semiconductor substrate protrudes.

Title: Medical device lubricant comprising radiation curable silicon material
Inventor: STEUBE GREGORY ALAN
IPC: C08G2/00
Filed: 2003-07-24
Abstract: The invention relates to a lubricant for medical devices. The inventive lubricant uses silicone epoxy and vinyl ether that both rapidly cure when exposed to ultraviolet light or an intense electron beam. The lubricants formulated with these components in combination with a secondary silicone component and a photoinitator offer improved performance when compared to lubricants formulated from the prior art method of using a RTV + silicone fluid materials. The speed of the UV/EB cure of the new components makes lubricants formed from them more compatible with high speed manufacturing processes by eliminating the delay of prior art lengthy cure steps.

Title: Personalized surround sound headphone system
Inventor: SHTEYN EUGENE
IPC: H04R5/027
Filed: 2003-12-04
Abstract: A system and method determines parameters (170) for rendering headphone audio information, based on a user's preferred acoustic rendering in a non-headphone environment. A user configures a loudspeaker-based system for a preferred ambiance. Microphones (150) on a head-mounted device then detect the audio signals received by the user in this environment.
