A method and system of lossless compression of integer data using a novel backward-adaptive technique. The adaptive Run-Length and Golomb / Rice (RLGR) encoder and decoder (codec) and method switches between a Golomb / Rice (G / R) encoder mode only and using the G / R encoder combined with a Run-Length encoder.

Ion implantation is carried out to form a p-well region and a source region in parts of a high resistance SiC layer on a SiC substrate, and a carbon film is deposited over the substrate. With the carbon film deposited over the substrate, annealing for activating the implanted dopant ions is performed, and then the carbon film is removed. Thus, a smooth surface having hardly any surface roughness caused by the annealing is obtained. Furthermore, if a channel layer is epitaxially grown, the surface roughness of the channel layer is smaller than that of the underlying layer. Since the channel layer having a smooth surface is provided, it is possible to obtain a MISFET with a high current drive capability.

A method and system of lossless adaptive Golomb / Rice (G / R) encoding of integer data using a novel backward-adaptive technique having novel adaptation rules. The adaptive G / R encoder and decoder (codec) and method uses adaptation rules that adjust the G / R parameter after each codeword is generated. These adaptation rules include defining an adaptation value and adjusting the G / R parameter based on the adaptation value. If the adaptation value equals zero, then the G / R parameter is decreased by an integer constant. If the adaptation value equals one, then the G / R parameter is left unchanged. If the adaptation value is greater than one, then the G / R parameter is increased by the adaptation value. In addition, the adaptive G / R encoder and method include fractional adaptation, which defines a scaled G / R parameter in terms of the G / R parameter and updates and adapts the scaled G / R parameter to slow down the rate of adaptation.
