Filed: 1993-12-27
Abstract: PURPOSE:To inexpensively obtain an activated carbon having high porosity and adsorption performance by carbonizing a prepleg obtained by impregnating a sheet like fiber base material with a phenolic resin varnish. CONSTITUTION:The prepleg is obtained by impregnating the sheet like fiber base material with the phenolic resin varnish and drying and the objective activated carbon is obtained by carbonizing the prepleg at >=400 deg.C.

IPC: H01L29/78
Filed: 1998-11-20
Abstract: PROBLEM TO BE SOLVED: To suppress thinning and back gate bias effect by forming a punch through stopper layer to be deep in the center beneath a channel region under a gate electrode and to be shallower gradually toward the opposite ends of a channel region. SOLUTION: A punch through stopper layer 27A is formed to be deep in the center beneath a channel region under a gate electrode 4A and to be shallower gradually toward the opposite ends of a channel region. It is formed symmetrically to the channel length direction of the gate electrode 4A. When such a punch through stopper layer 27A is formed, impurity concentration is increased only in a passage causing punch through and equivalent substrate concentration decreases resulting in reduction of back gate bias effect. It is effective for a circuit where the characteristics are invariant even if a voltage is applied while changing the source and drain.
