Furthermore, a clock skew reduction device 105 changes the driving capability of every cell according to the extraction result of the delay information and accordingly the clock skew is reduced. A clock skew expansion value calculation device 106 calculates to decide the limit of expansion of a clock skew. As a result, every circuit never has a malfunction and also a clock signal skew is expanded while the requested operating speed is satisfied for the circuit.

Title: Reference voltage supplying circuit
Inventor: KOBAYASHI TOMOKO
IPC: H01L27/04
Filed: 1990-03-22
Abstract: PURPOSE:To reduce the threshold voltage dependency and to quickly follow up the variance of a supply voltage by combining first and second complementary reference potentials generating circuits and a third potential generating circuit, which compensates generated potentials and controlling a reference potential driving circuit. CONSTITUTION:The threshold voltage of MOSFETs Q2 and Q3 is denoted as VTN, and that of MOSFETs Q1 and Q4 is denoted as VTP. The reference potential generating circuits A1, B1 cancel the deviation by forming the deviation generated from the reference potential set with the variance in a manufucturing process in the case of the single use to the complementary form and the refer ence potential having less dependency to the voltages VTN and VTP is generated. A reference potential generating circuit C1 compansates the generated potentials of circuits A1 and B2 to control a reference potential driving circuit D1. Thus, the dependency upon threshold voltages of FETs is reduced to quickly follow up the variance of the supply voltage.

Title: Cleaning and drying method for compound
Inventor: KATSURA SHIGEO
IPC: H01L21/304
Filed: 1993-04-01
Abstract: PURPOSE:To obtain a substrate having a surface coated uniformly with thin oxide and free from heavy metal contamination and uneven drying by cleaning the substrate with ultrapure water having low dissolved oxygen concentration and then drying the substrate by spin drying or blow drying. CONSTITUTION:A mirror polished compound semiconductor single crystal substrate is subjected to organic cleaning for removing residual wax used for fixing the substrate or dust particles adhering to the surface. The substrate is then cleaned using ultrapure water where the concentration of dissolved oxygen is 0.5ppm or below to wash out the organic solvent followed by spin drying or blow drying. Consequently, the dissolved oxygen in a water drop is prevented from reacting on GaAs to produce Al2O3, and causing uneven drying. Furthermore, oxide on the surface of the substrate can be made uniform and as thin as 2nm or less thus obtaining a substrate where the surface concentration of heavy metal is 1X10<10>atom/cm<2> after cleaning.
