Abstract: Correcting light intensity for photolithography may include irradiating light having a first light intensity distribution through a photo mask having a mask pattern to a photosensitive layer on a wafer to form a first pattern corresponding to the mask pattern. A distribution of critical dimensions of the first pattern corresponding to the mask pattern may be determined, and a second light intensity distribution may be determined based on a relation between the first light intensity distribution and the distribution of critical dimensions of the first pattern. Then, light having the second light intensity distribution may be irradiated. Related systems are also discussed.

Abstract: An apparatus and method for providing controlled heating, cooling and motion, in a device such as an active robotic automobile seat, are disclosed. A shape memory alloy (SMA) element, which changes shape upon application of a temperature change to the SMA element, is coupled to a thermoelectric device. Heat flows through the TED upon application of an electrical current through the TED. The apparatus is operable in one of a plurality of modes. In a first mode, a current is applied through the TED to cause a temperature change in the SMA element to change the shape of the SMA element. In a second mode, a current is applied to the TED to cause heat flow in a space adjacent to the apparatus. By controlling application of current to the TED, controlled motion, heating and cooling are achieved in the seat.

Abstract: A semiconductor device having a thyristor-based memory device exhibits improved stability under adverse operating conditions related to temperature, noise, electrical disturbances and light. In one particular example embodiment of the present invention, a semiconductor device includes a thyristor-based memory device that uses a shunt that effects a leakage current in the thyristor. The thyristor includes a capacitively-coupled control port and anode and cathode end portions. Each of the end portions has an emitter region and an adjacent base region. In one implementation, the current shunt is located between the emitter and base region of one of the end portions of the thyristor and is configured and arranged to shunt low-level current therebetween. In connection with an example embodiment, it has been discovered that shunting current in this manner improves the ability of the device to operate under adverse conditions that would, absent the shunt, result in inadvertent turn on, while keeping the standby current of the memory device to an acceptably low level.

Abstract: A circuit for detecting the amount of radio frequency power provided by an amplifier. The circuit contains an array of coupled transistors in two power amplifiers, and a log-detector circuit, all resident on a single semiconductor die. The main power amplifier contains the larger array of transistors to amplify the radio frequency signal for feeding to an antenna, and a secondary power amplifier contains a smaller array of transistors to provide a scaled output that is proportional to the amplified radio frequency signal and is used to control the main power amplifier. The log-detector circuit converts the signal from the secondary power amplifier to a full-wave rectified log-linear DC signal that is logarithmically proportional to the controlling signal. The DC signal output from the log-detector circuit is fed to the main power amp to control it.
