Abstract: Some embodiments of the present disclosure relate to a processing tool. The tool includes a housing enclosing a processing chamber, and an input/output port configured to pass a wafer through the housing into and out of the processing chamber. A back-side macro-inspection system is arranged within the processing chamber and is configured to image a back side of the wafer. A front-side macro-inspection system is arranged within the processing chamber and is configured to image a front side of the wafer according to a first image resolution. A front-side micro-inspection system is arranged within the processing chamber and is configured to image the front side of the wafer according to a second image resolution which is higher than the first image resolution.

Abstract: An embodiment of the invention provides a method for a location tracking, applied to a mobile device, an indoor access point (AP) and at least one indoor Internet of Things (IoT) device, comprising: receiving, by the indoor AP, a first set of location information of the mobile device from the mobile device at outdoor, wherein the first set of location information is determined according to a Global Navigation Satellite System (GNSS); determining, by the indoor AP, a second set of location information of the indoor AP according to the first set of location information; determining, by the indoor AP, a third set of location information of the at least one indoor IoT device according to the second set of location information; and transmitting, by the indoor AP, the third set of location information to the at least one indoor IoT device.

Abstract: A superabsorbent polymers and a method of forming the same are provided. The method is processed by adding calcined shell powders to a free radical polymerization. The superabsorbent polymers with more micropores can be obtained. Therefore, absorptivity and permeability for the liquid of the superabsorbent polymers are increased, and diffusibility and liquid conductivity of the superabsorbent polymers are also improved.

Abstract: The invention discloses a small token device, ideally about the size of a key, which can plug into the USB interface of a host computer, which need not be fully trusted, and handle a variety of different security functions. The device is capable of serving as a secure USB hub, and thus can function on a host computer that only has one available USB port. Among the multiple functions that the device can perform include communicating through the internet in a secure manner, storing data in a secure manner, and access secure information through public key (PKI) methods. The invention also allows secure USB peripherals to maintain security while being hooked up to either a non-secure host computer or other non-secure USB peripherals.

Abstract: A semiconductor memory device with internal self-refreshing is provided. The invented memory device has a programmable internal oscillator for controlling a self-refreshing time period. The internal oscillator obviates the need for an external signal for refreshing data stored in the device's memory cells. The pin-out configuration of the device is analogous to the pin-out configuration of an SRAM device, so that the invented device can replace an SRAM device on a circuit board. The self-refreshing time period is programmable to different time periods depending upon the intended use of the device for minimizing power consumption by the device. The oscillator provides an output pulse for incrementing an address counter which generates internal refreshing addresses and also activates a memory word line for memory cell refreshing. A comparator compares an external address and the internal refreshing address generated by the counter.
