  • Patent number: 11698591
    Abstract: An EUV photolithography system utilizes a baseplate of an EUV pod to unload an EUV reticle from a chuck within an EUV scanner. The baseplate includes a top surface and support pins extending from the top surface. The when the reticle is unloaded onto the baseplate, the support pins hold the reticle at relatively large distance from the top surface of the baseplate. The support pins have a relatively low resistance. The large distance and low resistance help ensure that particles do not travel from the baseplate to the reticle during unloading.

  • Patent number: 11693560
    Abstract: An in-memory computing device includes in some examples a two-dimensional array of memory cells arranged in rows and columns, each memory cell made of a nine-transistor current-based SRAM. Each memory cell includes a six-transistor SRAM cell and a current source coupled by a switching transistor, which is controlled by input signals on an input line, to an output line associates with the column of memory cells the memory cell is in. The current source includes a switching transistor controlled by the state of the six-transistor SRAM cell, and a current regulating transistor adapted to generate a current at a level determined by a control signal applied at the gate. The control signal can be set such that the total current in each output line is increased by a factor of 2 in each successive column of the memory cells.

  • Patent number: 11687011
    Abstract: A reticle carrier described herein is configured to quickly discharge the residual charge on a reticle so as to reduce, minimize, and/or prevent particles in the reticle carrier from being attracted to and/or transferred to the reticle. In particular, the reticle carrier may be configured to provide reduced capacitance between an inner baseplate of the reticle carrier and the reticle. The reduction in capacitance may reduce the resistance-capacitance (RC) time constant for discharging the residual charge on the reticle, which may increase the discharge speed for discharging the residual charge through support pins of the reticle carrier. The increase in discharge speed may reduce the likelihood that an electrostatic force in the reticle carrier may attract particles in the reticle carrier to the reticle.

  • Patent number: 11658206
    Abstract: A deep trench structure may be formed between electrodes of a capacitive device. The deep trench structure may be formed to a depth, a width, and/or an aspect ratio that increases the volume of the deep trench structure relative to a trench structure formed using a metal etch-stop layer. Thus, the deep trench structure is capable of being filled with a greater amount of dielectric material, which increases the capacitance value of the capacitive device. Moreover, the parasitic capacitance of the capacitive device may be decreased by omitting the metal etch-stop layer. Accordingly, the deep trench structure (and the omission of the metal etch-stop layer) may increase the sensitivity of the capacitive device, may increase the humidity-sensing performance of the capacitive device, and/or may increase the performance of devices and/or integrated circuits in which the capacitive device is included.
