Abstract: Epitaxial source/drain structures for enhancing performance of multigate devices, such as fin-like field-effect transistors (FETs) or gate-all-around (GAA) FETs, and methods of fabricating the epitaxial source/drain structures, are disclosed herein. An exemplary device includes a dielectric substrate. The device further includes a channel layer, a gate disposed over the channel layer, and an epitaxial source/drain structure disposed adjacent to the channel layer. The channel layer, the gate, and the epitaxial source/drain structure are disposed over the dielectric substrate. The epitaxial source/drain structure includes an inner portion having a first dopant concentration and an outer portion having a second dopant concentration that is less than the first dopant concentration. The inner portion physically contacts the dielectric substrate, and the outer portion is disposed between the inner portion and the channel layer. In some embodiments, the outer portion physically contacts the dielectric substrate.

Abstract: A method for forming a light absorption layer including the following steps is provided. A controlling precursor is wet coated on a base precursor. The band gap of the controlling precursor is larger than that of the base precursor. The controlling precursor is a Group I-III-VI compound, and the Group I-III-VI compound is composed of Cua(In1-b-cGabAlc)(Se1-dSd)2, wherein 0<a, 0?b?1, 0?c?1, 0<b+c?1, and 0?d?1. Then, a heating process is performed so as to make the base precursor and the controlling precursor form the light absorption layer.

Abstract: The invention relative to a positioning device for the scanned object of a scanner may make a positioning function to a document or a book to be scanned. Through designing a positioning element on the shell body of a scanner, a book of many pages may be positioned or secured on the positioning element, which may be designed on the scanning window. According to the size, the form, or the thickness of the book, an appropriate positioning element may be used, and its number is selectively applied. The book is placed on the positioning element, wherein the middle recession part of the book is placed at the top end of the positioning element, by which a bulged-out part is formed and sandwiched into the middle recession part of the book to thereby secure the book in the positioning element.

Abstract: The present invention is to provide a shaft sleeve of a scanner, the scanner having an optical chassis that is capable of moving along the linear direction defined by a guiding rod, comprising: an trunk, a wedging mechanism, and a transmission part. The trunk having a gliding groove capable of connected with the guiding rod. The wedging mechanism provided at one side of the trunk, capable of connecting with the optical chassis. The transmission part provided on the trunk and connected with a driving device, for enabling the truck to move along the linear direction defined by the guiding rod. The optical chassis is capable of choosing a connection with the shaft sleeve to move along the linear direction defined by the guiding rod or the optical chassis is capable of choosing a separation from the shaft sleeve.
