Abstract: An improved gate structure for a MOSFET device exhibits a reduced level of 1/f noise or “flicker noise”, while maintaining the control of boron penetration into the substrate of the MOSFET device. The gate structure for the MOSFET device includes a gate electrode and a gate oxide layer wherein nitrogen is selectively implanted into the gate oxide/device substrate interface prior to oxidation of the gate oxide layer. The nitrogen is selectively implanted so that the nitrogen is implanted into thin gate oxide regions and masked from thick gate oxide regions so that the benefits of controlling the boron penetration are realized while the 1/f noise is reduced due to the selective implantation of the nitrogen.

Abstract: A windmill apparatus includes: a frame body structure adapted to be positioned on a flat top of a construction; a main shaft vertically installed in the middle of the frame body structure; a first main-shaft sleeve rotatably coupled with a lower part of the main shaft; a belt pulley fixed around a lower end of the first main-shaft sleeve; a rotation control device with a revolving arrangement rotatably installed around the first main-shaft sleeve; a direction control device installed in a closed upper portion of the frame body structure and mechanically coupled with the rotation control device for automatically effecting wind direction change; and a wind direction indicating device rotatably installed on top of the frame body structure and movably coupled with the direction control device for relaying wind direction change therefrom; thereby, wind force can be effectively utilized with minimal manufacturing cost.
