  • Patent number: 9346209
    Abstract: Disclosed are a feedblock multiplier with thickness gradient variation, a feedblock system, a method, and multilayer structure made by the method. The feedblock multiplier combines the functionalities of feedblock and multiplier conventionally used for producing the multilayer structure. The feedblock multiplier includes an input section for feeding fluid materials. A feedblock section is included for dividing the fluid delivered into multiple channels correspondingly. The fluids in the channels are segmented into two or more fluid segments by a segmenting section. The each fluid segment is delivered through corresponding channel-conversion section with thickness-gradient variation in the feedblock multiplier. Each channel-conversion section includes multiple channels with configurable positions. The fluids are then combined in a multiplier section for producing the multilayer structure with overlapped layers. The multilayer structure is outputted from an extruding section.

  • Publication number: 20160137492
    Abstract: The present disclosure relates to method of forming a MEMS device that mitigates the above mentioned difficulties. In some embodiments, the present disclosure relates to a method of forming a MEMS device, which forms one or more cavities within a first side of a carrier substrate. The first side of the carrier substrate is then bonded to a dielectric layer disposed on a micro-electromechanical system (MEMS) substrate, and the MEMS substrate is subsequently patterned to define a soft mechanical structure over the one or more cavities. The dielectric layer is then selectively removed, using a dry etching process, to release the one or more soft mechanical structures. A CMOS substrate is bonded to a second side of the MEMS substrate, by way of a bonding structure disposed between the CMOS substrate and the MEMS substrate, using a low-temperature bonding process.

  • Patent number: 9343656
    Abstract: Methods and apparatuses for a magnetic tunnel junction (MTJ) which can be used in as a magnetic random access memory cell are disclosed. The MTJ comprises a free layer and an insulator layer. The MTJ further comprises a pinned layer with a first region, a second region, and a third region. The second region is of a first length and of a first thickness, and the first region and the third region are of a second length and of a second thickness. A ratio of the first thickness to the second thickness may be larger than 1.2. A ratio of the second length to the first length is larger than 0.5. The first thickness may be larger than a spin diffusion length of a material for the pinned layer. So formed MTJ results in increased tunneling magnetic resistance ratio and reduced critical switch current of the MTJ.
