In a DCFL circuit, a high-speed operation is conducted in a stable state regardless of its load capacitance. The circuit includes a buffer circuit. Added to the buffer circuit is a pull-up circuit conducting a pull-up operation for a predetermined period of time when an output potential of the circuit changes from a low level to a high level. A first EFET of the pull-up circuit includes a gate electrode connected to an output terminal of a logic stage, a drain electrode coupled with a positive power source, and a source electrode linked with a drain of a second EFET. The second EFET includes a gate electrode connected to a node linked in series to a resistor element. The resistor is coupled with an input terminal. The second EFET includes the drain electrode connected to a source electrode of the first EFET and a source electrode linked with an output terminal. Due to the operation of the pull-up circuit for a fixed period of time, the propagation delay time can be minimized without increasing the steady state current when the output potential changes from a low level to a high level.

A GaAs substrate is divided at boundary regions of unit cells of FET chips. With such construction, magnitude of curling of the GaAs substrate due to a difference of thermal expansion coefficients between the GaAs substrate and the PHS upon heating during assembling, can be reduced. In a semiconductor device with a PHS, the magnitude of curling of the semiconductor substrate after assembling can be reduced by reducing stress upon assembling, without causing degradation of reliability.

In a state estimating apparatus, an input space quantization section quantizes an input space according to a required precision of output data. A storage section calculates and stores the number of times of occurrence of output data corresponding to each input event in the quantized input space, the mean values of the output data, and the change amounts of the output data. A neighborhood definition section calculates an input space neighborhood satisfying the required precision of the output. A similar case extraction section zooms up the predetermined neighborhood of the input space to the predetermined degree and extracts input case similar to the neighborhood from input case in the input space. A similarity determination section determines the similarity between the new input event and the extracted similar input cases on the basis of the degree of zooming. An estimating section selects input cases corresponding to the similarity from the similar input case, and estimates a value of output data corresponding to the new input event on the basis of the mean value of output data and the mean value of change amounts of the output data.
