Publication number: 20240121373Abstract: Disclosed are an image display method and a 3d display system. The method is adapted to the 3d display system including a 3d display device and includes the following steps. A first image and a second image are obtained by splitting an input image according to a 3d image format. Whether the input image is a 3D format image complying with the 3D image format is determined through a stereo matching processing performed on the first image and the second image. An image interweaving process is enabled to be performed on the input image to generate an interweaving image in response to determining that the input image is the 3D format image complying with the 3D image format, and the interweaving image is displayed via the 3D display device.Type: ApplicationFiled: May 10, 2023Publication date: April 11, 2024Applicant: Acer IncorporatedInventors: Kai-Hsiang Lin, Hung-Chun Chou, Wen-Cheng Hsu, Shih-Hao Lin, Chih-Haw Tan

Patent number: 8288219Abstract: A stack of two polysilicon layers is formed over a semiconductor body region. A DDD implant is performed to form a DDD source region in the semiconductor body region along a source side of the polysilicon stack but not along a drain side of the polysilicon stack. Off-set spacers are formed along opposing side-walls of the polysilicon stack. A source/drain implant is performed to form a drain region in the semiconductor body region along the drain side of the polysilicon stack and to form a highly doped region within the DDD source region such that the extent of an overlap between the polysilicon stack and each of the drain region and the highly doped region is inversely dependent on a thickness of the off-set spacers, and a lateral spacing directly under the polysilicon stack between adjacent edges of the DDD source region and the highly doped region is directly dependent on the thickness of the off-set spacers.Type: GrantFiled: March 20, 2008Date of Patent: October 16, 2012Assignee: Hynix Semiconductor, Inc.Inventors: Peter Rabkin, Hsingya Arthur Wang, Kai-Cheng Chou

Patent number: 6818504Abstract: Structures and methods for flash memory transistors are formed with self-aligned drain/source contacts. The flash transistors are formed with a plurality of gate layers. An etch resistant layer(s) are deposited on top of the gate layers in the memory array transistors and on the gate layers of peripheral transistors. An additional oxide layer/spacer may be formed on the etch resistant layer to control the resulting transistor junction configuration. As a result within the same process various transistors may be formed satisfying various requirements. Contact holes to the drain and source regions of the memory and peripheral transistors are then formed. The etch resistant layer prevents the contact etchants from completely etching away the protective etch resistant layer surrounding the gate layers. The spacing between the drain/source contacts and the gate layers can be greatly reduced increasing the density of the memory array transistors and reducing chip size.Type: GrantFiled: August 10, 2001Date of Patent: November 16, 2004Assignee: Hynix Semiconductor America, Inc.Inventors: Peter Rabkin, Hsingya Arthur Wang, Kai-Cheng Chou
