  • Publication number: 20240145596
    Abstract: A device includes a fin extending from a semiconductor substrate; a gate stack over the fin; a first spacer on a sidewall of the gate stack; a source/drain region in the fin adjacent the first spacer; an inter-layer dielectric layer (ILD) extending over the gate stack, the first spacer, and the source/drain region, the ILD having a first portion and a second portion, wherein the second portion of the ILD is closer to the gate stack than the first portion of the ILD; a contact plug extending through the ILD and contacting the source/drain region; a second spacer on a sidewall of the contact plug; and an air gap between the first spacer and the second spacer, wherein the first portion of the ILD extends across the air gap and physically contacts the second spacer, wherein the first portion of the ILD seals the air gap.

  • Patent number: 11948820
    Abstract: The present invention provides a latching guide structure arranged inside a door of semiconductor carrier. The latching guide structure comprises an upper latching part, a lower latching part, at least one elastic unit and a driver. Moreover, a first guiding portion of the upper latching part is matched with a second guiding portion of the lower latching part, therefore to define the installation space for the at least one elastic unit. On the other hand, the driver simultaneously actuates an upper actuating unit of the first guiding portion and a lower actuating unit of the second guiding portion to linearly move in reverse direction therebetween. The range of the linear motion of the upper actuating unit and the lower actuating unit represents the compression or extension of the at least one elastic unit, determining to control the open/close status of the upper latching part and the lower latching part.

  • Patent number: 11878009
    Abstract: The present invention relates to a combination of a histone deacetylase (HDAC) inhibitor, chidamide in an acidic salt form, and a nonsteroidal anti-inflammatory drugs (NSAIDs), celecoxib in a basic salt form. The present invention also relates to methods which significantly regulate tumor microenvironment and therefore dramatically improve anti-cancer activity.

  • Patent number: 9061989
    Abstract: A method for producing terephthalic acid comprises the steps of: subjecting methyl acrylate to contact with aluminum chloride so as to form a complex; adding isoprene to the complex to result in a Diels-Alder reaction which is kept at a temperature no higher than 50° C. by cooling so as to obtain a cyclic adduct product; subjecting the cyclic adduct product to separation so as to obtain a cyclic para-precursor; and subjecting the cyclic para-precursor to a chemical reaction so as to obtain terephthalic acid.
