A display that includes energy sensors within the display itself is disclosed. An Organic Light Emitting Diode (OLED) can be made to operate both as a light emitter and as an energy detector. When forward biased with an appropriate driving signal, the OLED emits light via electroluminescence, which can be used to make a portion of an image on the display. In another mode, the OLED can detect energy by converting incoming photons or energy into an electrical signal by the photoelectric effect. By operating OLEDs in the display in both emissive and sensing modes, energy that shines on the display, such as from an outside source can be detected at the same time an image is shown. Additionally, a display including OLEDs can detect light energy generated by the display itself.

A tiled display may be formed on a substrate with a plurality of display elements which may be light emitting or non-light emitting display elements. A driver circuit for the display elements may be integrated into the display proximate to the display elements. In one embodiment, a complementary metal oxide semiconductor integrated circuit may form the driver circuit and may be secured within a recess in the same substrate on which said display elements are formed. The integrated circuit and the display elements may then be interconnected using conventional techniques.

An integrated circuit lattice chip for computation of dynamic programming (DP) recursions uses identical nodal processor units arranged in regular lattice form. Interconnections between processor units on the chip are programmable using non-volatile EEPROM connections. The nodal processor units have computing element for generating a distance metric representative of the difference between the i.sup.th and j.sup.th elements of the unknown and prototype vectors that is combined with a maximum partial or minimum cumulative distance metric of preselected set of lower order nodal processors to produce an optimal (maximum or minimum) cumulative distance value for unknown and prototype vector elements with indices equal to or less than (i, j). A network is also provided for identifying the optimal path through the lattice for use in designing a DP classification system.

A digital-to-analog converter includes a plurality of electrically programmable floating gate transistors, each having a electrically programmable threshold voltage. Each of the transistors has its source coupled to ground, its control gate coupled to an output node, and its drain coupled to the output node via one of a plurality of switching circuits. The output node is coupled to a voltage source via a load circuit. An input circuit decodes a digital input signal to selectively generate one of a plurality of control signals at a time in accordance with the digital input signal. Each of the control signals is for one of the switching circuits. When a transistor is coupled to the output node, the voltage level of the output node is equal to the threshold voltage of that transistor. An analog-to-digital converter includes a plurality of electrically programmable floating gate transistors, each having a electrically programmable threshold voltage. Each of the transistors has its source coupled to ground, its control gate coupled to an input analog voltage, and its drain coupled one of a plurality of output nodes. Each of the output nodes is coupled to the voltage source via its respective load circuit. The output circuit generates a digital output signal in accordance with the number of the transistors that are caused to be conducting by the input analog voltage.

An artificial neural network incorporating difference type, non-MP (McCullough-Pitts) neuron cells and a method and apparatus for training this network. More specifically, the output of each neuron cell is a nonlinear mapping of a distance metric of a difference vector and an offset. The difference vector is the difference between an input and a reference vector; the offset is representative of the radius of a hyperspheroidal discriminant function.

A self-apodizing collimator for collimating X-rays for use in VLSI lithography. The paraboloidal collimator uses a graded ML coating to collimate a range of wavelengths along the surface of the paraboloid such that a uniform resist response is provided. In addition, the collimated X-rays have a higher intensity than possible with a system using additional apodizing films.

A method of forming a patterned resist layer on a semiconductor substrate is described. The substrate is coated with a resist layer and placed on a substrate stage in a lithographic printer. The lithographic printer includes a pulsed radiation source that emits a radiation pulse lasting a pulse time and has a recovery time between two consecutive radiation pulses. The printer has a reticle disposed between the radiation source and the resist layer. The substrate is aligned to the reticle. A stepping field of the resist layer is patterned using a plurality of radiation pulses during multiple passes of the reticle over the stepping field. The substrate moves relative to the reticle at a predetermined velocity during each of the radiation pulses. The substrate motion relative to the reticle is configured so that the radiation source emits a radiation pulse when the center of the reticle is over about the center of the stepping field. A substantially patterned resist layer is formed faster and with less misalignment variance compared to the prior art.
